Ah, good catch. I just zipped my dev folder with the plugin (the .idea folder is not useless but you don't need it, right!). Thanks for fixing that!

Hello Daniel,
It works perfectly, thank you, it's great, I'm really pleased.
I've tested all the online or installable systems for tracking, but your plugin remains the safest solution for being informed of an update, it's on the site and sees all the available updates, which isn't the case with Watchful for example.
I saw that the files in the installation archive were in a subfolder and that for this reason the translation string in the xml file was not read. There is also a useless .idea folder with files.
As I've also adapted the FR language files, I'm sending you the cleaned-up archive with these new FR files.
Thanks again

Please try CUpdater 3 and let me know if it works fine on j4.

Hello Daniel,
I'm taking the liberty of repeating Stefan's question because I haven't found an equivalent. I've worked with Watchful since it was created, but it has never detected all the extensions, and only your plugin is capable of doing that.
That's why I'd be very interested in a version for Joomla 4, even with a subscription.
Thank you for your reply.
