v2.1.1

Updates the bundled update checker library to 5.7 and makes releases publish themselves. No breaking changes — upgrading is a drop-in replacement and needs no action on a site.

Changed

• Releases publish themselves once the version bump is merged: when a version without a tag reaches main, the release workflow creates the vX.Y.Z tag on that commit and publishes the GitHub Release, so a release no longer needs a tag pushed by hand. The release notes are now the version's section of this changelog, followed by GitHub's list of merged pull requests, so the update details a site shows for a new version describe what changed rather than listing pull request titles.
• yahnis-elsts/plugin-update-checker 5.6 → 5.7, the library that delivers plugin updates from GitHub Releases. The upstream release replaces wp_redirect() and htmlentities() with wp_safe_redirect() and esc_html(), adds an opt-in autoupdate field, and drops Bitbucket OAuth 1 support, which this plugin does not use (it only talks to GitHub). 5.7 renames the library's versioned namespace from v5p6 to v5p7, so the enableReleaseAssets() setup in smoxy.php now names v5p7; the package was installed into a WordPress site and the updater was confirmed to load. No action is needed on a site.
