v0.3.0
Download feedland-rivers-0.3.0.zip below — this is the installable plugin package.
The "Source code (zip)" and "Source code (tar.gz)" links further down are GitHub's raw repo checkout, not the plugin package: wrong root folder name, and includes dev-only files (composer.json, CLAUDE.md, etc.) that don't belong in a WordPress install and will produce spurious Plugin Check errors.
