There are now updated AppImages, Release Notes, and PDF/HTML manuals on the website and Andrey's packages are up to date at:         https://github.com/einhander/cin-gg-packages/releases
Release notes included below with some concern for the Speed mod as noted with no real concern for Blur and Titler.

GIT for Cinelerra-GG has the following changes from 04/01/2025-04/302025

Blend Algebra and Blend Program plugins:
An additional SYSLIB Blend Program of tone_mapping.bp has been created by Andrea
 for tonemapping an HDR media and report its values within the range (0, 1.0). For usage, reference
 Example 6 in the file at:
   https://cinelerra-gg.org/download/testing/BlendPluginExamples/Examples.txt
 For netBSD, modifications were added by Andrew to fix shebang-perl and to not use ldl in Makefile.
Other small changes include:
4.0 cmake requires 3 patches that Andrew has provided and Andrea had discovered/tested on Arch for
  x265 and libsvtav1.
A speed bug has been found and was described reproducibly by Lukas. A one line change to auto.C
  seems to fix it, but it is unknown if reverting that line will lead to a previously diagnosed problem
  reoccuring.
The old version of ffnvcodec (Video codec SDK) which was 10.0.26.0 was added back to the source as
  ffnvcodec-old.tar.xz to accommodate versions before the updated version of ffnvcodec for 12.2.72.0
  was installed as the default.
Blur and Titler plugins were modified so that these plugins can be used in combination with others (e.g.
 Blue Banana) without introducing the clipping into the process. Andrew provided the mod and
 Andrea tested it to ensure it worked without clipping and IgorB tested to make sure there was no
 impact to current usage of Blur and the Titler.
Tiff was updated from 4.6.0t to 4.7.0.
