+#### Maintain Releases and Project Listings
+
+Update versions and the verification date in `_data/releases.yml` using [RubyGems](https://rubygems.org/gems/grape/versions). Confirm that each versioned README or upgrade-guide tag exists. The default branch may describe an unreleased version; do not advertise that as a published release. Keep current, previous, and legacy release lines distinct without implying identical support policies.
+
+List only non-archived projects with recent substantive maintenance. Inspect default-branch commits, compatibility work, releases, and runnable setup instructions rather than relying on repository metadata timestamps or an isolated automated workflow bump. Apply the same standard to third-party integrations and examples, retain canonical repository links, and let each project define its own supported versions.
+
+Keep historical talks and tutorials clearly labeled rather than presenting them as current setup guidance. Preserve existing page paths and the `CNAME` custom domain. Keep Markdown paragraphs on one line.
