Btw I've recently backported several fixes to 1.7.x branch:
[[[
*) Fix attempt to free invalid memory on exit when apr_app is used
on Windows. [Ivan Zhakov]
*) Fix double free on exit when apr_app is used on Windows. [Ivan Zhakov]
*) Fix a regression in apr_stat() for root path on Windows. [Ivan Zhakov]
]]]
And CMake/GitHub Actions stuff.
