Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitHub with WP-CLI:
wp plugin install https://github.com/ronalfy/disable-plugin-and-theme-updates/archive/refs/heads/master.zipUpdates itself. It ships its own updater, so new versions appear under Dashboard → Updates.
WordPress - Disable Plugin and Theme Updates
Ready for testing. Use at your own risk, although feedback is much appreciated.
Docs coming soon. Promise!
