Release libgweather 3.90.0 (snapshot)
Is it porrenct versioning?
3.90 is lower than 40.0 as version.
So if it is for upcomming Gnome 42 version should be for exampel 42.0.apha1 https://discourse.gnome.org/t/new-gnome-versioning-scheme/4235
The versioning scheme is not meant for libraries, like that topic clearly explains.
Additionally, libgweather 4.0 (which is going to be released for GNOME 42, in March) is an API break release; as I recommend in my blog post and in the topics/issues on Discourse that I link from there, libgweather 4.0 should be packaged as libgweather4 or gweather-4, as it is going to be parallel installable with the older libgweather 3.x (and 40.0, which was sadly released with a weird version bump instead of continuing with the 3.x cycle).
