First of all, congratulation on the recent release of the 2.4.0 version!
I noticed that jogl-cg was not present on the 2.4.0 release, whereas it was available in v2.4.0-rc-20210111. Is this intended? I have not noticed any disclaimer of depreciation for this library. The native libjogl_cg was also removed.
There have been no issue so far to make the existing code run with 2.4.0 version combined with v2.4.0-rc-20210111 version for jogl-cg, but I noticed that this specific RC was removed from the jogamp repositories (while it is still available from other repositories).
