OK. I don’t see anything critical, but I’m not one of the developers. Maybe opening a new topic would be useful, as the generic “3.8.0 released” topic may not draw much attention.
As for your log contents, I see the “Pango-CRITICAL” messages, but here is someone that also has them, and it appeared to me that their darktable was functioning properly:
I think the
36,149997 LUA ERROR : cannot open C:\Users\User\AppData\Local\darktable\luarc: No such file or directory
line is harmless (that file would exist if you installed Lua plugins, but those are not essential to using darktable).
So, please open a new topic, maybe others will be able to help more. Attach your log there, too.
