Stale comment

Risk assessment: Very Low

The current diff only adds a May 21 changelog entry to changelog.mdx (19 inserted lines). It doesn’t modify production codepaths, configuration, navigation, infrastructure, API behavior, auth/permissions, or security boundaries. I also didn’t find a CODEOWNERS file requiring owner review for this path.

The PR already has an approval from this automation, so I did not add a duplicate approval. No risk increase found in the current update.

New documentation references deprecated persistent browsers feature

Low Severity

This new changelog entry introduces a reference to "persistent browsers," which falls under the project rule that flags any new documentation mentioning "persistent sessions" (the rule explicitly lists "persistent browser sessions" as an example). While the intent here is to announce the EOL of the feature, the rule states these references in new documentation are to be removed or omitted. The migration guidance could be rephrased to avoid naming the deprecated concept directly.
