+- 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.
