v20.5.0

## Why

The Expo dashboard route for device run sessions moved to the simulator sessions surface, so EAS CLI should send users to that page and use the simulator-session terminology in user-facing output.

## How

- Add a dashboard URL helper that points device run sessions at `/simulator-sessions/{id}`.
- Update `eas simulator:{start,get,list}` output and JSON to expose `deviceRunSessionUrl` using the simulator sessions route.
- Update user-facing simulator command copy from "device run session" to "simulator session".

## Test Plan

CI should pass.

 ### 🧹 Chores
 
+## [20.4.0](https://github.com/expo/eas-cli/releases/tag/v20.4.0) - 2026-06-25
+
+### 🎉 New features
+
+- [eas-cli] New command `observe:session` for inspecting events by session ID. ([#3868](https://github.com/expo/eas-cli/pull/3868) by [@douglowder](https://github.com/douglowder))
+- [eas-cli] Add tiered build-credit usage warnings (approaching/at/over) before each build, lowering the warning threshold to 80% to match email notifications. ([#3882](https://github.com/expo/eas-cli/pull/3882) by [@sarahlane8](https://github.com/sarahlane8))
+
+### 🐛 Bug fixes
+
+- [eas-cli] Fix `eas update --channel` failing with "Channel has no branches associated with it" when the channel was auto-created by a build. A branch with the channel's name is now created and linked, matching the behavior for a channel that doesn't exist yet. ([#3891](https://github.com/expo/eas-cli/pull/3891) by [@gwdp](https://github.com/gwdp))
+
+## [20.3.0](https://github.com/expo/eas-cli/releases/tag/v20.3.0) - 2026-06-18
+
+### 🎉 New features
+
+- [eas-cli] Add `eas account:audit [ACCOUNT_NAME]` command to view an account's audit logs. ([#3863](https://github.com/expo/eas-cli/pull/3863) by [@keith-kurak](https://github.com/keith-kurak))

+
+### 🐛 Bug fixes
+
+- [eas-cli] `eas integrations:posthog:connect` no longer aborts when `npx expo install` reports an error (for example, on a dynamic app config); it finishes writing the environment variables and prints any remaining manual steps. ([#3877](https://github.com/expo/eas-cli/pull/3877) by [@gwdp](https://github.com/gwdp))

+- [eas-cli] Add support for non-interactive `eas update:rollback [GROUP_ID]`. The given update group must be the latest for its branch and runtime version; the previous update group is republished, or a roll back to the embedded update is published if there is none.

+All changes should be validated before committing. At minimum run package-level tests (e.g. `jest-unit`)
+for touched code, then run type checks/linting and format the repo:
 
 ```bash
+yarn fmt            # Apply Oxfmt formatting
 yarn typecheck      # Validate TypeScript types
