Basically we never silently delete reported bugs (by respect for the time spent to do the report) so some old one can still be around if:
it’s a niche bug (ie: having a small impact)
it takes too much time to fix
we don’t know how to fix it
A few years ago, I decided as a personal challenge to get the reported bugs count below 100 for the compiler, all platforms included. It took time but I guess it should be the case once 6.21 final lands !
8th is very actively developed with active bug tracker. There is a new release about once a month, usually with almost all the reported bugs fixed and some nice features added. Last month Nuklear graphics backend got updated from SDL2 to SDL3.
