Adding Changelog Entries

When adding changelog entries to published packages (devtools_shared, devtools_app_shared, and devtools_extensions), follow these rules:

• Check Publication State: Never add an entry to an already published version (e.g. # 12.1.0). You MUST check which versions are published on pub.dev (e.g., at https://pub.dev/packages/<package_name>/versions) before determining section headers! If a version is not yet published, it should be suffixed with the next numeric -wip tag (e.g., ## 0.5.1-wip) or follow the existing convention in the file, such as (not released). You should also match the existing header level (H1 or H2) used for versions in that file. Avoid generic placeholder headers like # WIP!
• New Version Headers: If a version bump is required, you MUST first use the instructions in updating-package-versions to update the package version in pubspec.yaml, and then add a new header to the changelog file with the new version (e.g., ## 0.5.1-wip) before adding your entries.
• Accurately Distinguish Packages: Ensure that the cleanups or edits applied to a specific package's changelog entries belong strictly to that package path (e.g., changes in devtools_app do not warrant entries in devtools_shared).
• Conciseness and Accuracy: Describe clearly what was changed and why. Avoid generic descriptions without context, such as "Fixes missing deprecation message". Indicate specifically what was added or removed.
• User visible changes ONLY: Only add entries in the changelog if the change is meaningful to consumers of the package. Do not include internal refactoring notes or other trivial changes that users do not care about.
