Plugin status

Please read this: https://www.e-dynamics.be/wordpress/forums/topic/security-release/

(it is also mentioned in this forum)

They don’t (I verified several other plugins I use, a well-known management plugin, wp core, and some other event plugins), but since they had no vulnerability to solve, they are not required to refactor the code … it’s a pity that WP plugin-managers require a complete code refactoring and refuse me to release at least the security fix. Anyway, the plugin is still existing and maintained, but one can consider it a “premium” plugin now (albeit free, but no longer hosted on wp.org).
While I hope you reconsider, I understand your point of view. It’s a free world and a free plugin after all 🙂

I’m using https://github.com/YahnisElsts/plugin-update-checker for updates, and since that plugs into site_transient_update_plugins , it should be no problem.
