The October 31, 2021 CinGG releases are at:

GIT for Cinelerra-GG has the following changes from 10/01/2021-10/31/2021
The instructions for using AppImage in the file, README_appimage.txt, was updated by Terje.
Cineform, DPX, MXF additional render formats have been provided as used in ffmpeg by Andrea.
Title video plugin now correctly fades in/out as reported by Camille. This bug had been around a
  very long time (see BT #559) with the fix now done by a Freelancer.
Many plugins were being reloaded in the AppImage on every start which could take awhile on some
 computers. MatN has expertly fixed this and changed that of the Cinelerra_plugins also. Note that
 any time a new release/build is started for the first time, it will always reload the plugins but each
 subsequent usage of that image will no longer require reloads as long as you use the same .bcast5.
Andrew-R contributions:
 Opus and aom thirdparty libraries have had the examples and extras deleted to save build time.
 In support of Android/Termux CinGG compile, patches for libwepb and libaom have been added.
 Defaults for mxf render format have now been established.
Hungarian translation as created using google with a 90% automated procedure is now available. To
