As of this writing Catalina is still in public beta. Nobody should load a public beta, much less this one, onto their house servers. If you have already done so I am supplying a hardened and notarized version of the app for running on Catalina.
As of XTension version 9.4.21 the following plugins are unavailable on Catalina. Do NOT upgrade your server if you require any of these plugins. I am rebuilding these as people let me know which ones they are still using but do not have time frames when they will be available yet.
Do not update to Catalina if you need any of those plugins. Additionally please let me know via email if you are still using any of the plugins not already scheduled for an update so I can add them to my list.
