If you have a Zig project that is pinned on Zig 0.13.0, now is a great time to upgrade to the latest master branch release. Our goal during Release Month is to ensure everyone gets a smooth upgrade, so if that is not the case for you, please speak up!

So I did, and I found there were quite a few changes done to the std library on the build side, which inevitably breaks some libraries.
These changes include switching std.builtin.Type.Struct to std.builtin.Type.@"struct", for example.

I couldn't figure out all the changes, but this should be looked into in Zig-ImGui.
