We still support old (EOL) versions of macOS and Linux, so Windows 7 should still be supported (within reason). I will do a test with a newer version of mingw and see what happens, if this creates more issues than it’s worth we just drop Windows 7 support in 2.3.15.
We still support older macOS versions because older mac hardware cannot run the newest versions. This is not true of Windows hardware: all hardware that supported Win7 also supports Win10. We especially don’t want to introduce bugs in the Win builds.
