The getentropy() + function is blocking to generate very good quality entropy, os.urandom() + doesn't need such high-quality entropy. -- Issue #25688: Fixed file leak in ElementTree.iterparse() raising an error. +- Issue #25182: The stdprinter (used as sys.stderr before the io module is + imported at startup) now uses the backslashreplace error handler. -- Issue #23914: Fixed SystemError raised by unpickler on broken pickle data. +- Issue #25131: Make the line number and column offset of set/dict literals and + comprehensions correspond to the opening brace. -- Issue #25691: Fixed crash on deleting ElementTree.Element attributes. +- Issue #25150: Hide the private _Py_atomic_xxx symbols from the public + Python.h header to fix a compilation error with OpenMP.

Patch by Dingyuan Wang. +Library +------- + +- Issue #25626: Change three zlib functions to accept sizes that fit in + Py_ssize_t, but internally cap those sizes to UINT_MAX. This resolves a + regression in 3.5 where GzipFile.read() failed to read chunks larger than 2 + or 4 GiB. The change affects the zlib.Decompress.decompress() max_length + parameter, the zlib.decompress() bufsize parameter, and the + zlib.Decompress.flush() length parameter. - Issue #25583: Avoid incorrect errors raised by os.makedirs(exist_ok=True) when the OS gives priority to errors such as EACCES over EEXIST.
