- Issue #6466: now distutils.cygwinccompiler and distutils.emxccompiler
|
||||
uses the same refactored function to get gcc/ld/dllwrap versions numbers.
|
||||
It's `distutils.util.get_compiler_versions`. Added deprecation warnings
|
||||
for the obsolete get_versions() functions.
|

|

- Issue #6433: fixed issues with multiprocessing.pool.map hanging on empty list
|

- Issue #6314: logging: Extra checks on the "level" argument in more places.
