1. Update Platform & Dependency Parameters

gradle.properties:
- Update dartPluginVersion to the latest public Dart plugin release version. Fetch the latest version from JetBrains Marketplace (e.g. via curl -s "https://plugins.jetbrains.com/api/plugins/6351/updates?size=1" | jq -r '.[0].version' or by checking JetBrains Marketplace Dart Plugin) and set dartPluginVersion in gradle.properties to that version (e.g., dartPluginVersion= 508.0.0).
- If dropping support for older platform versions, update sinceBuild to the new lower bound (e.g., sinceBuild=252). Note: untilBuild is omitted for open-ended platform compatibility.
New Platform Version Compatibility & Baselines:
- When supporting/verifying a new platform release (e.g., IntelliJ 2026.3 / build 263):
  - Update the verification loop in tool/github.sh (for version in ...; do).
  - Run ./tool/update_baselines.sh to generate or update the plugin verifier baseline files in tool/baseline/<version>/verifier-baseline.txt.
JxBrowser License Key:
- Ensure resources/jxbrowser/jxbrowser.properties is present (copy from local environment if creating a new git worktree).

2. Fix API & Dependency Compatibility

Check for compilation errors or API signature changes introduced by the updated dependencies (e.g., websocket/DTD exception handling changes in FlutterInitializer.java and FlutterApp.java).
Run ./gradlew testClasses to confirm the codebase compiles against updated dependencies.

3. Update Changelog (`CHANGELOG.md`)

Compatibility Changes PR:
- Document compatibility updates under ### Changed in CHANGELOG.md with the PR reference (e.g., - Removed upper build constraint (\untilBuild`) for open-ended platform compatibility. (#9063)`).
Release Version Bump:
- Rename ## Unreleased to ## <VERSION>.0.0 (e.g., ## 95.0.0).
- Ensure all user-facing changes since the last release are categorized and tagged with PR numbers.
- Insert a fresh empty ## Unreleased block at the top with:
```
## Unreleased

### Added

### Changed

### Removed

### Fixed
```

4. Build & Validation

Run ./gradlew testClasses to verify Java/Kotlin compilation.
Run ./gradlew verifyPluginStructure to validate plugin.xml structure.
Run ./gradlew test to ensure all unit tests pass.
Run ./gradlew buildPlugin -Prelease -PversionedName to build the prospective release plugin zip artifact (Flutter-<VERSION>-<COMMIT>.zip) in build/distributions/.
Upload Prospective Zip: Manually upload the generated release zip (Flutter-<VERSION>-<COMMIT>.zip) from build/distributions/ to the team's Google Drive folder (e.g. DevExp Flutter Releases) for team-wide manual testing prior to public publishing.

5. Manual Testing Checklist

Perform manual sanity checks across every supported platform version (e.g. IntelliJ IDEA 2025.3, 2026.1, 2026.2 and Android Studio 2025.3 / Meerkat):

Create New Project: Verify new Flutter project wizard succeeds.
Open Existing Project: Verify existing Flutter project opens cleanly.
Run & Debug: Run app, hit breakpoints, and inspect variables.
Hot Reload & Hot Restart: Perform Hot Reload (⚡) and Hot Restart on a running app.
DevTools: Open DevTools tool windows (Inspector, Memory, Network, etc.).
Version-Specific Features: Verify any release-specific fixes or changes (e.g. Flutter SDK path changes in Settings, DTD theme synchronization, EAP installation compatibility).
