+# Changesets
+
+Every PR that changes a package adds a changeset: a Markdown file in this directory that names the changed packages, the bump type, and a one-line summary for the changelog. Do not edit `CHANGELOG.md` files. The release generates them from the changesets.
+
+## Add a changeset
+
+```sh
+yarn changeset
+```
+
+Select the changed packages and the bump type, then write the summary. Commit the new file with your PR. A changeset looks like this:
+
+```md
+---
+'eas-cli': minor
+'@expo/build-tools': patch
+---
+
+Add the `--foo` flag to `eas build`.
+```
+
+Write the summary as one sentence in the style of the existing `CHANGELOG.md` entries. The release adds the PR link and the author, and prefixes the entry with the package directories, for example `[eas-cli][build-tools]`.
+
+## Bump types and changelog sections
+
+All packages share one version. The highest bump in all changesets sets the next version. Each entry goes into the root `CHANGELOG.md` section for its highest bump:
+
+| Bump    | Root `CHANGELOG.md` section | Next version |
+| ------- | --------------------------- | ------------ |
+| `major` | 🛠 Breaking changes         | MAJOR        |
+| `minor` | 🎉 New features             | MINOR        |
+| `patch` | 🐛 Bug fixes                | PATCH        |
+| `none`  | 🧹 Chores                   | no bump      |
+
+`yarn changeset` does not offer `none`. For changes that should not appear in the changelog, add the "no changelog" label to the PR in GitHub.
+
+The "no changelog" label skips the changeset check, but not the `CHANGELOG.md` check. A PR that edits a `CHANGELOG.md` file always fails. Dependabot PRs skip the changeset check.
+
+See [RELEASING.md](../RELEASING.md) for how a release uses the changesets.

-### 🛠 Breaking changes
+## [27.10.0](https://github.com/expo/eas-cli/releases/tag/v27.10.0) - 2026-11-13
 
 ### 🎉 New features
 
+- [build-tools] Add the experimental `experimental_emulator_capture_version` input to `eas/start_android_emulator`. The Android Emulator then preloads that version of the `expo-emulator-capture` agent and uses the lavapipe renderer, and later steps start expo-device-hub with the emulator capture on. When the agent cannot install, the emulator starts as before. Only web preview sessions support the capture for now, so other session types fail with an error when the input is set. ([#4827](https://github.com/expo/eas-cli/pull/4827) by [@krystofwoldrich-agent](https://github.com/krystofwoldrich-agent))
+- [eas-cli] Add `eas simulator:devices` to list the devices Expo suggests for a simulator session. ([#4879](https://github.com/expo/eas-cli/pull/4879) by [@brentvatne](https://github.com/brentvatne))
+
 ### 🐛 Bug fixes
 
+- [build-tools] Retry the first ngrok tunnel open of a device run session up to two times when ngrok rejects it with ERR_NGROK_802. The first open now waits 19 seconds instead of 15, so a tunnel that opens late is kept instead of closed. Startup can be cancelled during the retries, and a preview tunnel stops retrying when its session host finishes. ([#4874](https://github.com/expo/eas-cli/pull/4874) by [@szdziedzic](https://github.com/szdziedzic))
+- [eas-cli] Include the parent CLI command in telemetry to distinguish nested commands from direct usage. ([#4876](https://github.com/expo/eas-cli/pull/4876) by [@davidmokos](https://github.com/davidmokos))
+- [build-tools] Run worker SSH sessions as detached upterm sessions that reconnect on their own under the same session ID, and stop them with `upterm session stop`. ([#4857](https://github.com/expo/eas-cli/pull/4857) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+- [build-tools] Run the command a client passes with `eas workflow:ssh <id> <command>` in worker SSH sessions, in the build directory. ([#4863](https://github.com/expo/eas-cli/pull/4863) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+- [build-tools] Always download upterm for worker SSH sessions instead of using an `upterm` found on `PATH`. ([#4859](https://github.com/expo/eas-cli/pull/4859) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+
 ### 🧹 Chores
 
+- [eas-cli][build-tools] Bump Node.js to 22.23.5 to fix the CVEs in the [November 2026 Node.js security releases](https://nodejs.org/en/blog/vulnerability/november-2026-security-releases). ([#4889](https://github.com/expo/eas-cli/pull/4889) by [@ramonclaudio](https://github.com/ramonclaudio))
+
+## [27.9.0](https://github.com/expo/eas-cli/releases/tag/v27.9.0) - 2026-11-12
+
+### 🎉 New features
+
+- [eas-cli] Warn about Expo Simulators and EAS Workflows outages from status.expo.dev before `eas simulator:start` creates a session, and describe degraded performance and maintenance correctly in all outage warnings. ([#4873](https://github.com/expo/eas-cli/pull/4873) by [@szdziedzic](https://github.com/szdziedzic))
+
+## [27.8.0](https://github.com/expo/eas-cli/releases/tag/v27.8.0) - 2026-11-12
+
+### 🎉 New features
+
+- [eas-cli] Tell accounts without EAS Simulator access that it is available on the Starter, Production, and Enterprise plans and link to the billing page, instead of pointing at the waitlist. `simulator:availability --json` now returns `billingUrl` instead of `waitlistUrl`. ([#4866](https://github.com/expo/eas-cli/pull/4866) by [@szdziedzic](https://github.com/szdziedzic))
+
+### 🐛 Bug fixes
+
+- [build-tools] Point expo-device-hub at the scrcpy server copy in the `turtle-v2` bucket in Android device sessions, so a failed GitHub release download no longer fails the session. expo-device-hub falls back to GitHub when the copy is missing. ([#4848](https://github.com/expo/eas-cli/pull/4848) by [@sjkim-expo](https://github.com/sjkim-expo))
+- [build-tools] Fix black iOS session preview artifacts on multi-display Simulators by capturing the active display through serve-sim. ([#4777](https://github.com/expo/eas-cli/pull/4777) by [@gwdp](https://github.com/gwdp))
+
+  Skip automatic previews on older serve-sim versions that cannot exclude them from idle activity.
+
+- [build-tools] Report flow tags with the Maestro test results of jobs that run `maestro-runner`. The tags are read from the runner's `report.json`. ([#4853](https://github.com/expo/eas-cli/pull/4853) by [@hSATAC](https://github.com/hSATAC))
+- [build-tools] Send the session preview size to `preview-upload-session` and refresh it when the size changes. ([#4864](https://github.com/expo/eas-cli/pull/4864) by [@hirbod](https://github.com/hirbod))
+- [eas-cli] Remove the "Android emulator support is still in development" warning from `eas simulator`. ([#4870](https://github.com/expo/eas-cli/pull/4870) by [@szdziedzic](https://github.com/szdziedzic))
+- [build-tools] Send the width, height and source of simulator session screenshots (manual, agent-device and Argent, including Argent screenshot diffs) as artifact metadata, read from the image header. ([#4858](https://github.com/expo/eas-cli/pull/4858) by [@hirbod](https://github.com/hirbod))
+- [eas-cli][build-tools][eas-build-job] Fix sizes of 102.4 GB and larger being printed with a value about a million times too large, and share one `formatBytes` helper between `eas-cli` and `build-tools`. ([#4854](https://github.com/expo/eas-cli/pull/4854) by [@vonovak](https://github.com/vonovak))
+- [eas-cli] Package local Simulator app bundles for upload when the host supports gzip tar archives, and reject unsupported IPA and ZIP installs before uploading. ([#4684](https://github.com/expo/eas-cli/pull/4684) by [@gwdp](https://github.com/gwdp))
+
+  Fix packaging stalls for app bundles containing hard links and clean temporary archives when interrupted. Local app directories and `.tar.gz`/`.tgz` files require a host advertising archive support.
+
+- [eas-cli] Remove the `[EXPERIMENTAL]` label from `eas simulator` commands, except `eas simulator:egress` and the `--egress` flag. ([#4869](https://github.com/expo/eas-cli/pull/4869) by [@szdziedzic](https://github.com/szdziedzic))
+
+## [27.7.2](https://github.com/expo/eas-cli/releases/tag/v27.7.2) - 2026-11-10
+
+### 🐛 Bug fixes
+
+- [eas-cli] Add `--log-source` to `eas simulator` to select which Android logs a session records. ([#4823](https://github.com/expo/eas-cli/pull/4823) by [@vonovak](https://github.com/vonovak))
+- [build-tools] Start SSH session shells in the job's build directory instead of the worker's directory. ([#4843](https://github.com/expo/eas-cli/pull/4843) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+- [eas-cli] Show that the ssh session has ended, instead of saying SSH was not enabled, when `eas workflow:ssh` is given the ID of a finished build. ([#4842](https://github.com/expo/eas-cli/pull/4842) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+- [eas-cli] Show the ID argument and examples in `eas workflow:ssh --help`. ([#4829](https://github.com/expo/eas-cli/pull/4829) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+
+## [27.7.1](https://github.com/expo/eas-cli/releases/tag/v27.7.1) - 2026-11-10
+
+### 🐛 Bug fixes
+
+- [eas-cli][eas-json][build-tools][eas-build-job][steps][local-build-plugin][worker][simulator-launcher] Update `node-forge`, `tar`, `nanoid`, `minimatch`, `joi`, `ajv`, `yaml`, and `zod` to versions with fixes for published security advisories. ([#4847](https://github.com/expo/eas-cli/pull/4847) by [@tchayen](https://github.com/tchayen))
+- [build-tools] Strip the GitHub repository access token from the git remote before a sandbox agent starts. ([#4826](https://github.com/expo/eas-cli/pull/4826) by [@sswrk](https://github.com/sswrk))
+
+## [27.7.0](https://github.com/expo/eas-cli/releases/tag/v27.7.0) - 2026-11-10
+
+### 🎉 New features
+
+- [eas-cli] Add `--git-branch` and `--git-commit-hash` to `eas workflow:run` to record the branch and commit of the uploaded project. ([#4815](https://github.com/expo/eas-cli/pull/4815) by [@hSATAC](https://github.com/hSATAC))
+
+### 🐛 Bug fixes
+
+- [build-tools] Record Android emulator output and, when selected, device logcat during simulator sessions, and upload the last 20 MiB of each as a session artifact. ([#4822](https://github.com/expo/eas-cli/pull/4822) by [@vonovak](https://github.com/vonovak))
+- [eas-cli] Stop spinners from flickering when their text wraps onto a second line, such as the `simulator:start` queue message in a narrow terminal. ([#4850](https://github.com/expo/eas-cli/pull/4850) by [@brentvatne](https://github.com/brentvatne))
+
+## [27.6.0](https://github.com/expo/eas-cli/releases/tag/v27.6.0) - 2026-11-10
+
+### 🎉 New features
+
+- [build-tools] Reuse compatible prefetched Appium and XCUITest files without removing them during cleanup. Resolve explicit package versions, including `latest`, and reuse prepared tools only when they match. Use the launcher's runtime serve-sim version for warm adoption and recordings, including prereleases. ([#4837](https://github.com/expo/eas-cli/pull/4837) by [@gwdp](https://github.com/gwdp))
+- [eas-cli] Add the `--property key=value` flag to `eas observe:events` to filter events by a property value. ([#4812](https://github.com/expo/eas-cli/pull/4812) by [@Ubax](https://github.com/Ubax))
+- [simulator-launcher] Prepare pinned Appium, XCUITest and WebDriverAgent files with `prefetch`. ([#4836](https://github.com/expo/eas-cli/pull/4836) by [@gwdp](https://github.com/gwdp))
+- [simulator-launcher] Add `simulator-launcher prefetch` to cache Expo Go downloads. ([#4834](https://github.com/expo/eas-cli/pull/4834) by [@gwdp](https://github.com/gwdp))
+- [simulator-launcher] Use caller-supplied serve-sim, agent-device and Argent versions and include exact version inputs in claims. ([#4845](https://github.com/expo/eas-cli/pull/4845) by [@gwdp](https://github.com/gwdp))
+- [simulator-launcher] Add `simulator-launcher warmup` so consumers can warm up Simulators, install Expo Go and prepare native tool caches. The command stops its tools and shuts down the selected Simulators before returning. ([#4838](https://github.com/expo/eas-cli/pull/4838) by [@gwdp](https://github.com/gwdp))
+
+### 🐛 Bug fixes
+
+- [build-tools] Stop waiting for `com.apple.datamigrator` to exit before an iOS Simulator on iOS 27.2 or later counts as ready; there it stays resident, so the wait never finished. Earlier runtimes keep the wait. Take the readiness screenshot from the first integrated screen when the device lists several, so the iPhone Duo on iOS 27.2 passes the check. ([#4816](https://github.com/expo/eas-cli/pull/4816) by [@hSATAC](https://github.com/hSATAC))
+- [eas-cli] Stop suggesting other event names in `eas observe:events` when an event name with `--session-id`, `--app-version`, `--build-number`, or `--update-id` returns no events. ([#4813](https://github.com/expo/eas-cli/pull/4813) by [@Ubax](https://github.com/Ubax))
+- [build-tools] Require the sandbox worker token for sandbox jobs and remove the sandbox GraphQL fallback. ([#4808](https://github.com/expo/eas-cli/pull/4808) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+- [vm-tools] Run the macOS VM-tools service with interactive scheduling so Simulator startup and preview processes avoid launchd's default CPU and I/O throttling. ([#4833](https://github.com/expo/eas-cli/pull/4833) by [@gwdp](https://github.com/gwdp))
+
+## [27.5.0](https://github.com/expo/eas-cli/releases/tag/v27.5.0) - 2026-11-05
+
+### 🎉 New features
+
+- [eas-cli] Import ordered action configurations with `eas simulator:control --import` and show progress for each action. ([#4686](https://github.com/expo/eas-cli/pull/4686) by [@gwdp](https://github.com/gwdp))
+- [eas-cli] Reuse simulator control connections with `--keep-alive` or `simulator:control:connection open`. Set an idle timeout, inspect the connection, or close it without stopping the simulator session. Keep-alive currently supports macOS and Linux. ([#4791](https://github.com/expo/eas-cli/pull/4791) by [@gwdp](https://github.com/gwdp))
+- [eas-cli] Start simulator sessions from saved settings and apply control actions after readiness. ([#4687](https://github.com/expo/eas-cli/pull/4687) by [@gwdp](https://github.com/gwdp))
+- [eas-cli] Run `eas simulator` commands also as `eas simulators`, `eas emulator` and `eas emulators`, for example `eas emulators:start` or `eas simulators:list`. These aliases are hidden from help. ([#4794](https://github.com/expo/eas-cli/pull/4794) by [@szdziedzic](https://github.com/szdziedzic))
+- [eas-cli] List `eas workflow:ssh` in `eas --help`. ([#4793](https://github.com/expo/eas-cli/pull/4793) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+
+### 🐛 Bug fixes
+
+- [build-tools] Stop an agent-device session that is still starting up when it is stopped. ([#4666](https://github.com/expo/eas-cli/pull/4666) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Stop an Appium session that is still starting up when it is stopped. ([#4668](https://github.com/expo/eas-cli/pull/4668) by [@gwdp](https://github.com/gwdp))
+  Report temporary-directory cleanup failures when Stop interrupts Appium installation.
+- [build-tools] Stop an Argent session that is still starting up when it is stopped. ([#4667](https://github.com/expo/eas-cli/pull/4667) by [@gwdp](https://github.com/gwdp))
+- [eas-cli] Find the personal account by its owner instead of assuming that its name equals the username. ([#3922](https://github.com/expo/eas-cli/pull/3922) by [@byronkarlen](https://github.com/byronkarlen))
+- [build-tools][worker] Use the sandbox worker token for sandbox jobs when www provides one, and keep Expo credentials out of the commands of those jobs. ([#4807](https://github.com/expo/eas-cli/pull/4807) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+- [eas-cli] Show the Expo Simulators hint after a successful build from November 12 instead of November 10. ([#4817](https://github.com/expo/eas-cli/pull/4817) by [@williamgrosset](https://github.com/williamgrosset))
+- [build-tools] Stop a web-preview session that is still starting up when it is stopped. ([#4669](https://github.com/expo/eas-cli/pull/4669) by [@gwdp](https://github.com/gwdp))
+
+### 🧹 Chores
+
+- [build-tools] Extract the worker API client core from the device run session worker API client. ([#4806](https://github.com/expo/eas-cli/pull/4806) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+
+## [27.4.1](https://github.com/expo/eas-cli/releases/tag/v27.4.1) - 2026-11-04
+
+### 🐛 Bug fixes
+
+- [simulator-launcher][build-tools] Wait for a starting warm Simulator launcher before claiming its session, instead of falling back to a cold start. ([#4810](https://github.com/expo/eas-cli/pull/4810) by [@gwdp](https://github.com/gwdp))
+
+## [27.4.0](https://github.com/expo/eas-cli/releases/tag/v27.4.0) - 2026-11-03
+
+### 🎉 New features
+
+- [simulator-launcher][build-tools] Add `eas/start_warm_appium_remote_session`, which runs the Appium session on the warm Simulator, or starts cold. An `appium` claim stops the unused tools first, so WDA does not share the Simulator with the agent-device runner. ([#4735](https://github.com/expo/eas-cli/pull/4735) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Add warm iOS session steps (`eas/start_warm_serve_sim_remote_session`, `eas/start_warm_agent_device_session`, `eas/start_warm_argent_remote_session`). They run the existing session on the warm Simulator, or start cold. `eas/start_agent_device_session` also accepts `install_app_path` and `launch_app_identifier`. ([#4723](https://github.com/expo/eas-cli/pull/4723) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Update the app version and build number from the final application archive, so the build shows the values the native build resolved. ([#3499](https://github.com/expo/eas-cli/pull/3499) by [@kadikraman](https://github.com/kadikraman))
+
+### 🐛 Bug fixes
+
+- [build-tools] Upload the final agent-device session artifacts before stopping the daemon, including sessions that reuse a warm Simulator. ([#4750](https://github.com/expo/eas-cli/pull/4750) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Add internal helpers that claim the warm Simulator through the launcher and adopt it on the warm serve-sim. Skip the Expo Go install when the warm Simulator already has the same Expo Go version. ([#4724](https://github.com/expo/eas-cli/pull/4724) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Recover warm Simulator recordings when their MP4 exists before the shutdown manifest is ready. ([#4789](https://github.com/expo/eas-cli/pull/4789) by [@gwdp](https://github.com/gwdp))
+- [eas-cli] Show the Expo Simulators hint after a successful build from November 10 instead of November 5. ([#4801](https://github.com/expo/eas-cli/pull/4801) by [@williamgrosset](https://github.com/williamgrosset))
+
+### 🧹 Chores
+
+- [build-tools] Move iOS Simulator startup behind a shared session host contract. ([#4752](https://github.com/expo/eas-cli/pull/4752) by [@gwdp](https://github.com/gwdp))
+
+## [27.3.0](https://github.com/expo/eas-cli/releases/tag/v27.3.0) - 2026-11-02
+
+### 🎉 New features
+
+- [eas-build-job] Add optional Observe error context to workflow jobs. ([#4787](https://github.com/expo/eas-cli/pull/4787) by [@AbbanMustafa](https://github.com/AbbanMustafa))
+
+### 🐛 Bug fixes
+
+- [eas-cli] Bump `@expo/apple-utils` to `2.3.0` to fix iOS capability sync when App Store Connect rejects enabling, disabling or changing a capability. ([#4790](https://github.com/expo/eas-cli/pull/4790) by [@douglowder](https://github.com/douglowder))
+- [eas-cli] Keep already linked App Groups, Merchant IDs and iCloud containers when capability sync links another identifier. ([#4584](https://github.com/expo/eas-cli/pull/4584) by [@ceydaakin](https://github.com/ceydaakin))
+- [worker] Mask secrets in every record the worker process writes to its stdout: the build log records and the worker's own records. ([#4782](https://github.com/expo/eas-cli/pull/4782) by [@hSATAC](https://github.com/hSATAC))
+- [worker][build-tools] Stop warmup in the background for jobs that do not use the warm Simulator, so job setup does not wait for it. Before build-tools boots or clones a Simulator, it waits until the launcher's state file records that cleanup finished, and fails if cleanup does not finish in time. ([#4721](https://github.com/expo/eas-cli/pull/4721) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Recover unhealthy device-session tunnels without changing their URLs and block further traffic when shutdown starts, even if ngrok cleanup times out. ([#4526](https://github.com/expo/eas-cli/pull/4526) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Stop sending the SSH host when registering an SSH session. ([#4784](https://github.com/expo/eas-cli/pull/4784) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+
+## [27.2.0](https://github.com/expo/eas-cli/releases/tag/v27.2.0) - 2026-10-29
+
+### 🎉 New features
+
+- [build-tools] Use single-device previews when the session already has a valid device ID. ([#4733](https://github.com/expo/eas-cli/pull/4733) by [@gwdp](https://github.com/gwdp))
+- [eas-cli] Add an experiment that suggests Expo Update to coding agents after a build when the Free plan account is within 5 builds of the platform limit. ([#4758](https://github.com/expo/eas-cli/pull/4758) by [@williamgrosset](https://github.com/williamgrosset))
+- [eas-cli] Add `eas observe:traces` to list request trace spans (or a summary of span names and counts), `eas observe:trace` to display one trace as a span tree, and span rows in the `eas observe:session` timeline. ([#4772](https://github.com/expo/eas-cli/pull/4772) by [@kadikraman](https://github.com/kadikraman))
+- [simulator-launcher] Accept a comma-separated list of warm Simulators in `EXPO_SIMULATOR_DEVICE`; the first is the default. One serve-sim serves every listed device on one port. After the default device is ready, warmup preinstalls the latest stable Expo Go from one download and tries to disable apsd on the other devices, until a job claims one. A claim can select any listed device and reports its preinstalled Expo Go. ([#4764](https://github.com/expo/eas-cli/pull/4764) by [@gwdp](https://github.com/gwdp))
+- [simulator-launcher] Add `@expo/simulator-launcher`, which warms an iOS Simulator at VM boot and hands it to one EAS job (`start`, `claim`, `prepare-tools`, `stop`). ([#4722](https://github.com/expo/eas-cli/pull/4722) by [@gwdp](https://github.com/gwdp))
+- [eas-cli] Show a one-time Expo Simulators hint after a successful build. ([#4768](https://github.com/expo/eas-cli/pull/4768) by [@FiberJW](https://github.com/FiberJW))
+- [vm-tools] Add a macOS startup script loader that runs `/usr/local/share/vm-tools/startup.sh` once per VM boot. ([#4725](https://github.com/expo/eas-cli/pull/4725) by [@gwdp](https://github.com/gwdp))

+
+## [27.1.0](https://github.com/expo/eas-cli/releases/tag/v27.1.0) - 2026-10-28
+
+### 🎉 New features
+
+- [eas-cli] Display queued workflow runs: `workflow:run --wait` and `workflow:status` show a run waiting for its concurrency group and the run blocking it, and `workflow:cancel` includes queued runs in its selection list. ([#4258](https://github.com/expo/eas-cli/pull/4258) by [@hSATAC](https://github.com/hSATAC))
+- [eas-cli] Upload the workflow files that `uses` jobs reference, including nested ones, when running a local workflow file with `eas workflow:run`. ([#4769](https://github.com/expo/eas-cli/pull/4769) by [@sswrk](https://github.com/sswrk))
+
+### 🐛 Bug fixes
+
+- [build-tools] Explain App Store Connect error 90189 as a duplicate build number. ([#3461](https://github.com/expo/eas-cli/pull/3461) by [@sjchmiela](https://github.com/sjchmiela))
+- [eas-cli] Fail the command when EAS CLI cannot pull environment variables from EAS servers, instead of continuing without them. ([#4774](https://github.com/expo/eas-cli/pull/4774) by [@wschurman](https://github.com/wschurman))
+- [eas-cli] Format the generated root changelog before committing a release. ([#4773](https://github.com/expo/eas-cli/pull/4773) by [@gwdp](https://github.com/gwdp))
+- [build-tools][worker] Put the `NPM_TOKEN` registry credential in the builder's npm user config on EAS Build (`~/.npmrc`, or the file `NPM_CONFIG_USERCONFIG` names), where pnpm 10.34.2+ and 11.5.3+ still expand `${NPM_TOKEN}` (they ignore it in a project-level `.npmrc`). Explain what to change when the project's pnpm version needs a newer Node.js than the build runs, including when eas.json sets `node` or `pnpm`. ([#4729](https://github.com/expo/eas-cli/pull/4729) by [@hSATAC](https://github.com/hSATAC))
+- [build-tools] Install `@expo/repack-app` for the `eas/repack` step with npm in a sandbox that sees only `PATH` and its own `HOME`, so the build machine's npm and Yarn configuration cannot break the install, fetch it through the EAS npm cache when the job uses one, and show the installer output in the build log. The step no longer looks the version up separately before installing. When the npm cache fails, the install retries against the public registry like the project install does; the `eas/run_agent` agent CLI install shares the same helper and gains the same retry. ([#4728](https://github.com/expo/eas-cli/pull/4728) by [@hSATAC](https://github.com/hSATAC))
+- [eas-cli] Honor the `--non-interactive` flag in `workflow:cancel`; it was parsed but never applied, so automation could hang on the interactive picker. ([#4258](https://github.com/expo/eas-cli/pull/4258) by [@hSATAC](https://github.com/hSATAC))
+- [eas-cli] Stop reporting a finish time for workflow runs that have not finished: `workflow:runs` reports `finishedAt` only for runs in a final status. ([#4258](https://github.com/expo/eas-cli/pull/4258) by [@hSATAC](https://github.com/hSATAC))
+
+## [27.0.0](https://github.com/expo/eas-cli/releases/tag/v27.0.0) - 2026-10-27
+
+### 🛠 Breaking changes
+
+- [eas-cli] Write the reason a command failed to stderr, next to the `command failed.` line, instead of to stdout. A program that reads the reason from stdout must read stderr instead. ([#4592](https://github.com/expo/eas-cli/pull/4592) by [@vonovak](https://github.com/vonovak))
+
+### 🎉 New features
+
+- [eas-cli] Send the `permissions.account.role` from the build profile to request a role for the build's `EXPO_TOKEN`. ([#4734](https://github.com/expo/eas-cli/pull/4734) by [@wschurman](https://github.com/wschurman))

+- [build-tools] Run Appium through the prepared Full Disk Access helper when available on macOS. ([#4622](https://github.com/expo/eas-cli/pull/4622) by [@gwdp](https://github.com/gwdp))
+- [eas-cli] Show permission guidance, including `permissions.account.role` in eas.json, when a build request fails with an authorization error. ([#4760](https://github.com/expo/eas-cli/pull/4760) by [@wschurman](https://github.com/wschurman))
+- [eas-cli] Print the notice about eas-cli in project dependencies only when stderr is a terminal, so programs that read stderr get the command's error. ([#4591](https://github.com/expo/eas-cli/pull/4591) by [@vonovak](https://github.com/vonovak))
+- [eas-cli] Show account roles and credential permission limits in `eas login` when you are already logged in. ([#4759](https://github.com/expo/eas-cli/pull/4759) by [@wschurman](https://github.com/wschurman))
+- [build-tools] Identify the build or application archive when a download fails, and explain when the archive is no longer available. ([#4703](https://github.com/expo/eas-cli/pull/4703) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Run apsd setup in the background without delaying iOS app launch or preview readiness. ([#4706](https://github.com/expo/eas-cli/pull/4706) by [@gwdp](https://github.com/gwdp))

+- [eas-cli] Require explicit `host:` simulator-host upload paths and report missing local files. ([#4683](https://github.com/expo/eas-cli/pull/4683) by [@gwdp](https://github.com/gwdp))
+
+  Missing local absolute paths now require the `host:` prefix. Actions that require upload IDs accept local files and reject host paths with an explanation.
+
+- [build-tools] Handle a device session stopped during startup as normal cleanup instead of reporting a startup error. ([#4716](https://github.com/expo/eas-cli/pull/4716) by [@gwdp](https://github.com/gwdp))
+- [build-tools] Support idle timeouts for iOS web-preview-only sessions, resetting the timer when preview input arrives. ([#4731](https://github.com/expo/eas-cli/pull/4731) by [@gwdp](https://github.com/gwdp))

+
+### 🎉 New features
+
+- [eas-build-job][build-tools] Export `validateAndroidLaunchOptions` and `quoteAndroidShellCommand` from `@expo/eas-build-job`, so Android launch arguments can be checked for NUL characters and length before a simulator session starts, and check them before the emulator boots in agent-device sessions. ([#4696](https://github.com/expo/eas-cli/pull/4696) by [@brentvatne](https://github.com/brentvatne))
+- [eas-json] Add `permissions.account.role` to build profiles to request a role for the build's `EXPO_TOKEN`. ([#4732](https://github.com/expo/eas-cli/pull/4732) by [@wschurman](https://github.com/wschurman))

+- [eas-cli] Read the app config fewer times in `eas build` and other project commands. An iOS build now runs `expo config` 2 times instead of 6. ([`78ba760`](https://github.com/expo/eas-cli/commit/78ba76001b67c9971236af1a1d02e46c2f82d24a) by [@vonovak](https://github.com/vonovak))
+- [build-tools][steps] Stop printing workflow hook parsing messages in build logs: native builds showed them under an "Unknown build phase" group, and custom builds warned about unknown hook keys and hooks on steps that never run. ([#4717](https://github.com/expo/eas-cli/pull/4717) by [@hSATAC](https://github.com/hSATAC))

+- [eas-cli] Share one GraphQL client between the project ID check and the command, so commands send one fewer app query. ([#4646](https://github.com/expo/eas-cli/pull/4646) by [@vonovak](https://github.com/vonovak))
+- [eas-cli] Show why a simulator session failed in `eas simulator:get`, and add an `errors` array to its `--json` output. For an unknown error, `simulator:start` and `simulator:get` now show the failed step's error from the session logs. ([#4694](https://github.com/expo/eas-cli/pull/4694) by [@brentvatne](https://github.com/brentvatne))
+- [eas-cli] Show why a simulator session failed in `eas simulator:start`, such as an unknown `--device` name, instead of only the session status. ([#4693](https://github.com/expo/eas-cli/pull/4693) by [@brentvatne](https://github.com/brentvatne))

-   - Breaking changes → MAJOR
-   - New features → MINOR
-   - Otherwise → PATCH
-3. GitHub Actions workflow handles release automation
+1. Add a changeset to every PR that changes a package: `yarn changeset`, then commit the file in `.changeset/`. Never edit `CHANGELOG.md` files; the release generates them. See `.changeset/README.md`
+2. All packages share one version. The highest changeset bump wins:
+   - `major` → MAJOR (🛠 Breaking changes)
+   - `minor` → MINOR (🎉 New features)
+   - `patch` → PATCH (🐛 Bug fixes)
+   - `none` → no bump (🧹 Chores)

 ## Choosing the next version
 
-As stated above, the next EAS CLI version is chosen automatically based on the existing changelog entries under the unreleased section in **CHANGELOG.md**.
+The changesets in `.changeset/` choose the next version. All packages share one version (a changesets `fixed` group), and the highest bump in all changesets wins:
 
-The algorithm works as follows:
-
-- If there are any entries in the "🛠 Breaking changes" section, bump the MAJOR version.
-- Otherwise, if there are any entries in the "🎉 New features", bump the MINOR version.
+- If any changeset has a `major` bump, bump the MAJOR version.
+- Otherwise, if any changeset has a `minor` bump, bump the MINOR version.
 - Otherwise, bump the PATCH version.
+
+A release fails if there are no changesets, or if all of them are `none` or empty. To force a bump, merge a changeset with that bump type. See [`.changeset/README.md`](./.changeset/README.md) for how to write a changeset.
+
+## What a release writes
+
+`yarn release` (`scripts/src/versionPackages.ts`) does these steps:
+
+1. Reads the changesets and computes the new version.
+2. Runs `changeset version`. This bumps every `package.json`, writes each package's `CHANGELOG.md`, and deletes the changesets.
+3. Sets the version in `lerna.json`, updates `yarn.lock`, and regenerates `packages/eas-cli/README.md`.
+4. Adds the new section to the root `CHANGELOG.md`. The GitHub release and the Slack message use this section.
+5. Commits `vX.Y.Z`, tags it, and pushes. A dry run stops before this step.
+
+The tag push starts the [release workflow](./.github/workflows/release.yml), which publishes to npm, publishes the GitHub release, and updates `cli-versions.json`.
+
+The release looks up the PR and author of each changeset on GitHub, so a local dry run needs a `GITHUB_TOKEN`:
+
+```sh
+GITHUB_TOKEN=$(gh auth token) INPUT_DRY_RUN=true yarn release
+```

+# @expo/build-tools
+
+## 27.10.0
+
+### Minor Changes
+
+- Add the experimental `experimental_emulator_capture_version` input to `eas/start_android_emulator`. The Android Emulator then preloads that version of the `expo-emulator-capture` agent and uses the lavapipe renderer, and later steps start expo-device-hub with the emulator capture on. When the agent cannot install, the emulator starts as before. Only web preview sessions support the capture for now, so other session types fail with an error when the input is set. ([#4827](https://github.com/expo/eas-cli/pull/4827) by [@krystofwoldrich-agent](https://github.com/krystofwoldrich-agent))
+
+### Patch Changes
+
+- Retry the first ngrok tunnel open of a device run session up to two times when ngrok rejects it with ERR_NGROK_802. The first open now waits 19 seconds instead of 15, so a tunnel that opens late is kept instead of closed. Startup can be cancelled during the retries, and a preview tunnel stops retrying when its session host finishes. ([#4874](https://github.com/expo/eas-cli/pull/4874) by [@szdziedzic](https://github.com/szdziedzic))
+- Run worker SSH sessions as detached upterm sessions that reconnect on their own under the same session ID, and stop them with `upterm session stop`. ([#4857](https://github.com/expo/eas-cli/pull/4857) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+- Run the command a client passes with `eas workflow:ssh <id> <command>` in worker SSH sessions, in the build directory. ([#4863](https://github.com/expo/eas-cli/pull/4863) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+- Always download upterm for worker SSH sessions instead of using an `upterm` found on `PATH`. ([#4859](https://github.com/expo/eas-cli/pull/4859) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+
+## 27.9.0
+
+No changes in this release.
+
+## 27.8.0
+
+### Patch Changes
+
+- Point expo-device-hub at the scrcpy server copy in the `turtle-v2` bucket in Android device sessions, so a failed GitHub release download no longer fails the session. expo-device-hub falls back to GitHub when the copy is missing. ([#4848](https://github.com/expo/eas-cli/pull/4848) by [@sjkim-expo](https://github.com/sjkim-expo))
+- Fix black iOS session preview artifacts on multi-display Simulators by capturing the active display through serve-sim. ([#4777](https://github.com/expo/eas-cli/pull/4777) by [@gwdp](https://github.com/gwdp))
+
+  Skip automatic previews on older serve-sim versions that cannot exclude them from idle activity.
+
+- Report flow tags with the Maestro test results of jobs that run `maestro-runner`. The tags are read from the runner's `report.json`. ([#4853](https://github.com/expo/eas-cli/pull/4853) by [@hSATAC](https://github.com/hSATAC))
+- Send the session preview size to `preview-upload-session` and refresh it when the size changes. ([#4864](https://github.com/expo/eas-cli/pull/4864) by [@hirbod](https://github.com/hirbod))
+- Send the width, height and source of simulator session screenshots (manual, agent-device and Argent, including Argent screenshot diffs) as artifact metadata, read from the image header. ([#4858](https://github.com/expo/eas-cli/pull/4858) by [@hirbod](https://github.com/hirbod))
+- Fix sizes of 102.4 GB and larger being printed with a value about a million times too large, and share one `formatBytes` helper between `eas-cli` and `build-tools`. ([#4854](https://github.com/expo/eas-cli/pull/4854) by [@vonovak](https://github.com/vonovak))
+
+## 27.7.2
+
+### Patch Changes
+
+- Start SSH session shells in the job's build directory instead of the worker's directory. ([#4843](https://github.com/expo/eas-cli/pull/4843) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+
+## 27.7.1
+
+### Patch Changes
+
+- Update `node-forge`, `tar`, `nanoid`, `minimatch`, `joi`, `ajv`, `yaml`, and `zod` to versions with fixes for published security advisories. ([#4847](https://github.com/expo/eas-cli/pull/4847) by [@tchayen](https://github.com/tchayen))
+- Strip the GitHub repository access token from the git remote before a sandbox agent starts. ([#4826](https://github.com/expo/eas-cli/pull/4826) by [@sswrk](https://github.com/sswrk))
+
+## 27.7.0
+
+### Patch Changes
+
+- Record Android emulator output and, when selected, device logcat during simulator sessions, and upload the last 20 MiB of each as a session artifact. ([#4822](https://github.com/expo/eas-cli/pull/4822) by [@vonovak](https://github.com/vonovak))
+
+## 27.6.0
+
+### Minor Changes
+
+- Reuse compatible prefetched Appium and XCUITest files without removing them during cleanup. Resolve explicit package versions, including `latest`, and reuse prepared tools only when they match. Use the launcher's runtime serve-sim version for warm adoption and recordings, including prereleases. ([#4837](https://github.com/expo/eas-cli/pull/4837) by [@gwdp](https://github.com/gwdp))
+
+### Patch Changes
+
+- Stop waiting for `com.apple.datamigrator` to exit before an iOS Simulator on iOS 27.2 or later counts as ready; there it stays resident, so the wait never finished. Earlier runtimes keep the wait. Take the readiness screenshot from the first integrated screen when the device lists several, so the iPhone Duo on iOS 27.2 passes the check. ([#4816](https://github.com/expo/eas-cli/pull/4816) by [@hSATAC](https://github.com/hSATAC))
+- Require the sandbox worker token for sandbox jobs and remove the sandbox GraphQL fallback. ([#4808](https://github.com/expo/eas-cli/pull/4808) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+
+## 27.5.0
+
+### Patch Changes
+
+- Stop an agent-device session that is still starting up when it is stopped. ([#4666](https://github.com/expo/eas-cli/pull/4666) by [@gwdp](https://github.com/gwdp))
+- Stop an Appium session that is still starting up when it is stopped. ([#4668](https://github.com/expo/eas-cli/pull/4668) by [@gwdp](https://github.com/gwdp))
+  Report temporary-directory cleanup failures when Stop interrupts Appium installation.
+- Stop an Argent session that is still starting up when it is stopped. ([#4667](https://github.com/expo/eas-cli/pull/4667) by [@gwdp](https://github.com/gwdp))
+- Use the sandbox worker token for sandbox jobs when www provides one, and keep Expo credentials out of the commands of those jobs. ([#4807](https://github.com/expo/eas-cli/pull/4807) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+- Stop a web-preview session that is still starting up when it is stopped. ([#4669](https://github.com/expo/eas-cli/pull/4669) by [@gwdp](https://github.com/gwdp))
+
+## 27.4.1
+
+### Patch Changes
+
+- Wait for a starting warm Simulator launcher before claiming its session, instead of falling back to a cold start. ([#4810](https://github.com/expo/eas-cli/pull/4810) by [@gwdp](https://github.com/gwdp))
+
+## 27.4.0
+
+### Minor Changes
+
+- Add `eas/start_warm_appium_remote_session`, which runs the Appium session on the warm Simulator, or starts cold. An `appium` claim stops the unused tools first, so WDA does not share the Simulator with the agent-device runner. ([#4735](https://github.com/expo/eas-cli/pull/4735) by [@gwdp](https://github.com/gwdp))
+- Add warm iOS session steps (`eas/start_warm_serve_sim_remote_session`, `eas/start_warm_agent_device_session`, `eas/start_warm_argent_remote_session`). They run the existing session on the warm Simulator, or start cold. `eas/start_agent_device_session` also accepts `install_app_path` and `launch_app_identifier`. ([#4723](https://github.com/expo/eas-cli/pull/4723) by [@gwdp](https://github.com/gwdp))
+- Update the app version and build number from the final application archive, so the build shows the values the native build resolved. ([#3499](https://github.com/expo/eas-cli/pull/3499) by [@kadikraman](https://github.com/kadikraman))
+
+### Patch Changes
+
+- Upload the final agent-device session artifacts before stopping the daemon, including sessions that reuse a warm Simulator. ([#4750](https://github.com/expo/eas-cli/pull/4750) by [@gwdp](https://github.com/gwdp))
+- Add internal helpers that claim the warm Simulator through the launcher and adopt it on the warm serve-sim. Skip the Expo Go install when the warm Simulator already has the same Expo Go version. ([#4724](https://github.com/expo/eas-cli/pull/4724) by [@gwdp](https://github.com/gwdp))
+- Recover warm Simulator recordings when their MP4 exists before the shutdown manifest is ready. ([#4789](https://github.com/expo/eas-cli/pull/4789) by [@gwdp](https://github.com/gwdp))
+
+## 27.3.0
+
+### Patch Changes
+
+- Stop warmup in the background for jobs that do not use the warm Simulator, so job setup does not wait for it. Before build-tools boots or clones a Simulator, it waits until the launcher's state file records that cleanup finished, and fails if cleanup does not finish in time. ([#4721](https://github.com/expo/eas-cli/pull/4721) by [@gwdp](https://github.com/gwdp))
+- Recover unhealthy device-session tunnels without changing their URLs and block further traffic when shutdown starts, even if ngrok cleanup times out. ([#4526](https://github.com/expo/eas-cli/pull/4526) by [@gwdp](https://github.com/gwdp))
+- Stop sending the SSH host when registering an SSH session. ([#4784](https://github.com/expo/eas-cli/pull/4784) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+
+## 27.2.0
+
+### Minor Changes
+
+- Use single-device previews when the session already has a valid device ID. ([#4733](https://github.com/expo/eas-cli/pull/4733) by [@gwdp](https://github.com/gwdp))
+
+### Patch Changes
+
+- Explain missing background task identifiers reported by App Store Connect. ([#3465](https://github.com/expo/eas-cli/pull/3465) by [@sjchmiela](https://github.com/sjchmiela))
+- Explain App Store Connect NOT_AUTHORIZED responses in the shared API client. ([#3462](https://github.com/expo/eas-cli/pull/3462) by [@sjchmiela](https://github.com/sjchmiela))
+- Explain App Store Connect UNEXPECTED_ERROR responses in the shared API client. ([#3467](https://github.com/expo/eas-cli/pull/3467) by [@sjchmiela](https://github.com/sjchmiela))
+- Explain missing app icons reported by App Store Connect, including codes 90022 and 90023, while preserving Apple’s validation details. ([#3466](https://github.com/expo/eas-cli/pull/3466) by [@sjchmiela](https://github.com/sjchmiela))
+- List failed Google Play commit attempts in order, including network failures, when the outcome is uncertain. ([#4660](https://github.com/expo/eas-cli/pull/4660) by [@sjchmiela](https://github.com/sjchmiela))
+- Fix a five-minute cleanup delay when a device session is canceled during startup and its screen recorder fails before connecting. ([#4761](https://github.com/expo/eas-cli/pull/4761) by [@gwdp](https://github.com/gwdp))
+- Handle TURN requests for a stopped device session without reporting a warning. ([#4762](https://github.com/expo/eas-cli/pull/4762) by [@gwdp](https://github.com/gwdp))
+- Preserve indented and incomplete Xcode compiler errors in formatted build logs, including the final diagnostic when logging stops. ([#4365](https://github.com/expo/eas-cli/pull/4365) by [@sjchmiela](https://github.com/sjchmiela))
+
+## 27.1.0
+
+### Patch Changes
+
+- Explain App Store Connect error 90189 as a duplicate build number. ([#3461](https://github.com/expo/eas-cli/pull/3461) by [@sjchmiela](https://github.com/sjchmiela))
+- Put the `NPM_TOKEN` registry credential in the builder's npm user config on EAS Build (`~/.npmrc`, or the file `NPM_CONFIG_USERCONFIG` names), where pnpm 10.34.2+ and 11.5.3+ still expand `${NPM_TOKEN}` (they ignore it in a project-level `.npmrc`). Explain what to change when the project's pnpm version needs a newer Node.js than the build runs, including when eas.json sets `node` or `pnpm`. ([#4729](https://github.com/expo/eas-cli/pull/4729) by [@hSATAC](https://github.com/hSATAC))
+- Install `@expo/repack-app` for the `eas/repack` step with npm in a sandbox that sees only `PATH` and its own `HOME`, so the build machine's npm and Yarn configuration cannot break the install, fetch it through the EAS npm cache when the job uses one, and show the installer output in the build log. The step no longer looks the version up separately before installing. When the npm cache fails, the install retries against the public registry like the project install does; the `eas/run_agent` agent CLI install shares the same helper and gains the same retry. ([#4728](https://github.com/expo/eas-cli/pull/4728) by [@hSATAC](https://github.com/hSATAC))
+
+## 27.0.0
+
+### Patch Changes
+
+- Keep the launched app open when an Appium iOS session starts. ([#4699](https://github.com/expo/eas-cli/pull/4699) by [@gwdp](https://github.com/gwdp))
+- Run Appium through the prepared Full Disk Access helper when available on macOS. ([#4622](https://github.com/expo/eas-cli/pull/4622) by [@gwdp](https://github.com/gwdp))
+- Identify the build or application archive when a download fails, and explain when the archive is no longer available. ([#4703](https://github.com/expo/eas-cli/pull/4703) by [@gwdp](https://github.com/gwdp))
+- Run apsd setup in the background without delaying iOS app launch or preview readiness. ([#4706](https://github.com/expo/eas-cli/pull/4706) by [@gwdp](https://github.com/gwdp))
+- Handle a device session stopped during startup as normal cleanup instead of reporting a startup error. ([#4716](https://github.com/expo/eas-cli/pull/4716) by [@gwdp](https://github.com/gwdp))
+- Support idle timeouts for iOS web-preview-only sessions, resetting the timer when preview input arrives. ([#4731](https://github.com/expo/eas-cli/pull/4731) by [@gwdp](https://github.com/gwdp))
+
+## 26.0.0
+
+### Major Changes
+
+- Remove legacy artifact type exports and route workflow uploads through workflow storage without file-type categories. Preserve workflow uploads and Maestro reports. ([#4719](https://github.com/expo/eas-cli/pull/4719) by [@sjchmiela](https://github.com/sjchmiela))
+
+### Minor Changes
+
+- Stop sandboxes after an optional maximum duration measured from readiness. ([#4702](https://github.com/expo/eas-cli/pull/4702) by [@sjchmiela](https://github.com/sjchmiela))
+- Unify signed URL uploading to a single implementation and use it everywhere. ([#4712](https://github.com/expo/eas-cli/pull/4712) by [@AHGIJMKLKKZNPJKQR](https://github.com/AHGIJMKLKKZNPJKQR))
+
+### Patch Changes
+
+- Default Android emulators to 4 GiB of RAM to reduce ADB disconnects during large transfers. Retain the 2 GiB default for API 34 and below outside interactive device sessions, and preserve explicit emulator configuration overrides. ([#4727](https://github.com/expo/eas-cli/pull/4727) by [@sjchmiela](https://github.com/sjchmiela))
+- Export `validateAndroidLaunchOptions` and `quoteAndroidShellCommand` from `@expo/eas-build-job`, so Android launch arguments can be checked for NUL characters and length before a simulator session starts, and check them before the emulator boots in agent-device sessions. ([#4696](https://github.com/expo/eas-cli/pull/4696) by [@brentvatne](https://github.com/brentvatne))
+- Retry transient failures when reporting that a device run session has started. ([#4680](https://github.com/expo/eas-cli/pull/4680) by [@gwdp](https://github.com/gwdp))
+- Retry the build lookup and the archive download of `eas/download_build` on transient failures, and name the failure cause in the build log. ([#4690](https://github.com/expo/eas-cli/pull/4690) by [@hSATAC](https://github.com/hSATAC))
+- Stop printing workflow hook parsing messages in build logs: native builds showed them under an "Unknown build phase" group, and custom builds warned about unknown hook keys and hooks on steps that never run. ([#4717](https://github.com/expo/eas-cli/pull/4717) by [@hSATAC](https://github.com/hSATAC))
+
+## 25.3.0
+
+### Minor Changes
+
+- Let serve-sim boot, install and launch Argent iOS sessions. ([#4602](https://github.com/expo/eas-cli/pull/4602) by [@gwdp](https://github.com/gwdp))
+- Let serve-sim boot, install and launch Appium iOS sessions. ([#4603](https://github.com/expo/eas-cli/pull/4603) by [@gwdp](https://github.com/gwdp))
+- Upload the screen recording session manifest as a JSON artifact alongside each video. ([#4689](https://github.com/expo/eas-cli/pull/4689) by [@gwdp](https://github.com/gwdp))
+
+### Patch Changes
+
+- Quote Android launch arguments and URLs for the device shell in simulator sessions, so values with spaces or shell characters reach `am start` as one argument; pass raw values and remove any shell quoting added as a workaround. ([#4695](https://github.com/expo/eas-cli/pull/4695) by [@brentvatne](https://github.com/brentvatne))
+- Wait up to five minutes for Google Play to finish processing an uploaded bundle before giving up on the edit commit. ([#4700](https://github.com/expo/eas-cli/pull/4700) by [@hSATAC](https://github.com/hSATAC))
+- Reset the device run session idle timer on iOS Simulator preview input. ([#4691](https://github.com/expo/eas-cli/pull/4691) by [@gwdp](https://github.com/gwdp))
+- Forward captured Simulator traffic through the local egress proxy. ([#4598](https://github.com/expo/eas-cli/pull/4598) by [@gwdp](https://github.com/gwdp))
+
+## 25.2.0
+
+### Minor Changes
+
+- Let serve-sim boot, install and launch agent-device iOS sessions with the local-egress guard. ([#4544](https://github.com/expo/eas-cli/pull/4544) by [@gwdp](https://github.com/gwdp))
+
+## 25.1.1
+
+### Patch Changes
+
+- Call www only through the device run session worker API in device run session jobs, and remove their GraphQL fallbacks. ([#4638](https://github.com/expo/eas-cli/pull/4638) by [@szdziedzic](https://github.com/szdziedzic))
+
+## 25.1.0
+
+### Minor Changes
+
+- Pass the `cors_origins` session input to serve-sim and expo-device-hub as `--cors-origin` origins, so a third party page can call the preview host API, for example with `@expo/hub-client`. ([#4657](https://github.com/expo/eas-cli/pull/4657) by [@krystofwoldrich](https://github.com/krystofwoldrich))
+- Pass the `frame_ancestors` session input to serve-sim and expo-device-hub as `--frame-ancestor` origins, so a third party can embed the preview host. ([#4655](https://github.com/expo/eas-cli/pull/4655) by [@krystofwoldrich](https://github.com/krystofwoldrich))
+
+### Patch Changes

+For serve-sim-owned iOS session startup, build-tools passes the guard through

+serve-sim adds its capability loader.

 Failure semantics: a missing library, a failed `launchctl setenv`, or a failed
 self-check fails the session, since a `--egress local` session without the
 guard would silently leak. Only an unwritable event log is a warning, because

-# RecordSim
-
-Small Swift library for non-exclusive iOS Simulator screen recording.
-
-It implements one recording path:
-
-1. Listen to SimRenderServer framebuffer callbacks.
-2. Copy the live `IOSurface` immediately into an owned `CVPixelBuffer`.
-3. Feed one continuous `AVAssetWriter`.
-4. Emit Apple HLS/CMAF-style fragmented MP4 segments.
-
-The output is suitable for uploading while recording. `session.json` contains
-the ordered segment metadata needed to build a playlist later.
-
-## Output
-
-```text
-session/
-  init.mp4
-  session.json
-  segments/
-    segment-000000.m4s
-    segment-000001.m4s
-```
-
-`init.mp4` is the fMP4 initialization segment. Individual `.m4s` files are not
-standalone MP4 files. `session.json` stores the wall-clock timestamp for the
-first video frame plus the metadata needed to build a playlist: HLS version,
-target duration, media sequence, `initSegment`, and the ordered `segments` array
-with file path and duration for each media segment.
-
-## CLI
-
-```bash
-swift run record-sim \
-  --udid <BOOTED_SIMULATOR_UDID> \
-  --output /tmp/sim-recording \
-  --segment-duration 120 \
-  --fps 30 \
-  --bitrate 30000000 \
-  --codec h264
-```
-
-For sparse 2h sessions, `--segment-duration 120` is a reasonable default: about
-60 media objects plus the init segment. The recorder appends a single duplicate
-hold frame near each segment boundary when the simulator is idle, so long idle
-periods still produce uploadable segments without encoding idle frames at 60fps.
-Use `--segment-duration 0` to write one continuous `recording.mp4` instead of
-`init.mp4` plus media segments.
-
-Frame timestamps use monotonic host time, not wall-clock time. The recorder also
-probes the framebuffer seed once per second; if the surface changes without
-callbacks for 5 seconds, it captures that frame and rewires the private callback
-registration.
-
-## Library
-
-```swift
-let recorder = SimulatorRecorder(
-  configuration: SimulatorRecordingConfiguration(
-    deviceUDID: udid,
-    outputDirectory: sessionDirectory,
-    segmentDuration: 120
-  )
-)
-
-recorder.onSegment = { segment in
-  // Enqueue upload of segment.url.
-}
-
-try recorder.start()
-try recorder.waitUntilFirstFrame()
-// ...
-let manifest = try recorder.stop()
-```
-
-`session.json` contains the precise wall-clock time for video PTS zero. In
-segmented mode it also contains the init segment and ordered media segment
-file/duration entries; in single-file mode it points at `recording.mp4`.
