I'm not familiar yet with the automated CI builds, I will go through the process in the next few days. If I understood correctly, you guys have always used that output for the windows releases so far (until Geany 2.0). If so it may be better to stick with that for now as I get to know better your build environments, in particular if you want to release Geany 2.1 soon. Note that I personally have always used MSYS2 for my windows builds but being a rolling distribution I have bumped in some regression a few times. I will investigate to understand if the CI libraries are more stable.
