I would almost increase this priority due to Blender 4.2 LTS is released.
(I had to downgrade blender to keep yusing CAS Sketcher)

What error did you face? It should already work, the remaining points here are for documentation and improvements for the installation through the new extension system.

Hi im not an old user. just try to use your add on based on a video tutorial. when im trying to enable it im getting this error. i just tried manualy copy files to location.

cannot import name 'bl_info' from 'bl_ext.user_default.CAD_Sketcher' (C:\Users\User\AppData\Roaming\Blender Foundation\Blender\4.2\extensions\user_default\CAD_Sketcher|init.py)

Where did you download the addon from? Try it with the latest version from github please.

With 4.2 there's now also the extension system. Did you also try to install it though this?

Hi, I tried through the extension system, still get the same error.

Posted the traceback. From what I can see the problem seems to be that the utilities script can't access the global variable bl_info. If I comment out the check that gets the version number from the variable and instead let it get the version from the manifest. It works fine. Hope this helps:)
