Hi, just want to let you know, that I managed to make the newer Cinny version to work with our old morph Webengine. This took downgrading of matrix-dsk and some patching. The RC for Cinny UT based on Cinny 4.10.0 can be downloaded here https://github.com/Danfro/cinny-ut/releases.
I made releases for focal (.1RC) and for noble (.nRC).
Here it seems to work fine, please let me know if you hit any new issues. I know, we still have plenty of old issues.
