With raisng the API version we also knew that user would not like and complain about it.
But more worse would be a crashing client. This was to avoid.
So what you and user can do is to contact the plugin author to update their plugins. And search for them on Github etc.
Our plugins (Control, Gamepad & Joystick, LUA, ClientQuery) are updated.
The G15 plugin won’t get any update and was removed from our myTS page for 1-2 years already.
All mentioned here already and a thing that happened in the past already.
In future it won’t get worse.
Acually there is no development happening on TS3 (excludes the bugs or issues that appeared with it).
