Yeah, if you started using `git-master` around ~7 years ago, it hasn't broken ever since. The last breaking release was v4.0 in 2016, but it was in development for years before that in the git-master branch. 3.5->4.0 was a pretty nasty upgrade process since we had to nuke a lot of the unsustainable things one last time (https://awesomewm.org/apidoc/documentation/17-porting-tips.m...).
Glad it works for you!
