After a while i take a look to the SailfishOS development again (
https://gitlab.com/sailfishos-porters-ci/cosmocom-ci/-/jobs/1247327268).
I seems that a version 4.0.1.48 was build 8 month ago. But tt seems that there is no further development for SailfisOS on cosmo :-(.
Did any one installed the latest build succsessful on the cosmo? I tried installation without success (after a few reboots it stops al the boot logo).
