-## [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))
-
-### 🐛 Bug fixes
-
-- [build-tools] 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))
-- [build-tools] 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))
-- [build-tools] 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))
-- [build-tools] 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))
-- [build-tools] 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))
-- [worker] Run package-manager version queries in parallel during worker preparation. ([#4710](https://github.com/expo/eas-cli/pull/4710) by [@gwdp](https://github.com/gwdp))
-- [worker] Start the Xcode version check in the background during worker tool preparation. Apply the Xcode 26.0 upload workaround when the query finishes, without delaying job startup. ([#4707](https://github.com/expo/eas-cli/pull/4707) by [@gwdp](https://github.com/gwdp))
-- [build-tools] 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))
-- [eas-cli] Remove the Free plan build limit guidance experiment for coding agents from `eas build`. ([#4757](https://github.com/expo/eas-cli/pull/4757) by [@williamgrosset](https://github.com/williamgrosset))
-- [worker] Allow jobs to skip installing the CocoaPods cache proxy with EAS_BUILD_DISABLE_COCOAPODS_CACHE_PLUGIN=1. ([#4709](https://github.com/expo/eas-cli/pull/4709) by [@gwdp](https://github.com/gwdp))
-- [build-tools] 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))
-- [build-tools] 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))
-
-### 🧹 Chores
-
-- [simulator-launcher] Add the state, request command and service helpers for the warm Simulator launcher. The package stays private until #4722 adds its CLI entry point. ([#4766](https://github.com/expo/eas-cli/pull/4766) 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))
-- [eas-cli] Add `simulator:logs` to read and follow logs from an iOS simulator session and download saved logs after it stops. ([#4545](https://github.com/expo/eas-cli/pull/4545) by [@gwdp](https://github.com/gwdp))
-
-### 🐛 Bug fixes
-
-- [build-tools] 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))
-- [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] Fix simulator control action help routing and show help when a flag is incomplete. ([#4681](https://github.com/expo/eas-cli/pull/4681) 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))
-
-### 🧹 Chores
-
-- [eas-cli] Run the GraphQL schema and generated code check on pull requests to any base branch, including stacked pull requests. ([#4763](https://github.com/expo/eas-cli/pull/4763) by [@wschurman](https://github.com/wschurman))
-
-## [26.0.0](https://github.com/expo/eas-cli/releases/tag/v26.0.0) - 2026-10-26

-
-### 🎉 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))
-- [build-tools] 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))
-- [build-tools] 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))

-### 🐛 Bug fixes
-
-- [eas-cli] Regenerate graphql code. ([#4692](https://github.com/expo/eas-cli/pull/4692) by [@wschurman](https://github.com/wschurman))
-- [build-tools] 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))
-- [build-tools] 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))

-- [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))
-- [worker] Retry Node.js installation without the internal Node.js cache mirror when the first attempt fails, while preserving other configured mirrors. ([#3452](https://github.com/expo/eas-cli/pull/3452) by [@sjchmiela](https://github.com/sjchmiela))
-- [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))
-- [worker] Mask secrets in every field of uploaded job log records, such as logged errors, not only in log messages. ([#4698](https://github.com/expo/eas-cli/pull/4698) by [@brentvatne](https://github.com/brentvatne))

 # @expo/build-tools
 
-## 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))

-
-- 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))
