To be honest I hope libtiff build patches, ffmpeg-5.1.patch999 and ffmpeg filters build fix for new ffmpeg will find their way in, because they fix build breakage on Andrea's updated Arch.
The compile for these patches works but I have not done any testing yet.  Since Andrea has tested successfully, I still would feel more comfortable if I could also.

My "early quit from filetiff/filetga/filepng" patches might wait for more testing (notably I hope they does not leak file descriptors or such, I only tested on short, less than minute video).

On further plans ... May be if ffmpeg 6.1 fails to materialize in first half of september we will go with 6.0, preparing new plugin info and such? So far ffmpeg.git was  not worse than 5.1 for me but seeking in mkv might be different (it was different in MPlayer).

Other updates might include x265 git (aarch64 stuff, build warning with new nasm fixed), libjpeg-turbo 3.0.0/3.0.1, libtiff 4.5.1, removal of openjpeg (ffmpeg.git removed support for it, and we does not use it directly), adding lcms2 lib so ffmpeg can use it ...

Also, I wonder if optipng run over our icons (or even pngquant, at least on those we have svg source for) might be useful? Standard set of icons weight nearly 8mb and stuffed directly into executable ....

But this is just reminder about ideas I have, my vision and visual taste  not good enough for saying definitively about icon quality before/after.

Will comment on the rest of this later.
