brotli/CHANGELOG.md
Evgenii Kliuchnikov 9686382ff3 PY: continue renovation of extension 
Fixed unchecked malloc for "tail" input data.
Fixed inconsistencies in docstrings.

Rewritten "growable buffer" to C-code, so it could run without acquiring GIL.

Breaking changes:
 - native object allocation failures now handled at object creation time
 - some lower level exceptions (e.g. OOM) are not shadowed by brotli.error
