v8.0.0

• #231 via #232: Remove custom setup.cfg
  parser handling, allowing the project (including sdist)
  to build/run on setuptools 41.4. Now building cheroot
  requires setuptools 30.3 or later (for declarative
  config support) and preferably 34.4 or later (as
  indicated in pyproject.toml).

v7.0.0

• #224: Refactored "open URL" behavior in cheroot.test.webtest to
  rely on retry_call.
  Callers can no longer pass raise_subcls or ssl_context
  positionally, but must pass them as keyword arguments.

v6.6.0

• Revisit #85 under #221. Now backports.functools_lru_cache is only
  required on Python 3.2 and earlier.
• cherrypy/cherrypy#1206 via #204: Fix race condition in threadpool
  shrink code.

  under PowerPC.

v6.5.7

• #198 via 9f7affe: Fix race condition when toggling stats counting
  in the middle of request processing.

• Improve post Python 3.9 compatibility checks.

• Fix support of abstract namespace sockets.

v6.5.6

• #218 via #219: Fix HTTP parser to return 400 on invalid major-only HTTP version in Request-Line.

v6.5.5

• #99 via #186: Sockets now collect statistics (bytes read and written) on Python 3 same as Python 2.

• cherrypy/cherrypy#1618 via #180: Ignore OpenSSL's 1.1+ Error 0 under any Python while wrapping a socket.

  under Python 3.

  dist metadata.

• #95: Fully integrate :py:mod:trustme into all TLS tests.
  Also remove all hardcoded TLS certificates.

• #42: Remove traces of :py:mod:unittest and
  :py:mod:ddt usage.

• Fix invalid input processing in
  :py:func:cheroot._compat.extract_bytes.

• Fix returning error explanation over plain HTTP for PyOpenSSL.

• Add a fallback for :py:func:os.lchmod where it's missing.

• Avoid traceback for invalid client cert with builtin
  :py:mod:ssl adapter.

• Avoid deprecation warning with :py:class:OpenSSL.SSL.Connection.

• Fix socket wrapper in PyOpenSSL adapter.

• Improve tests coverage:

  • Client TLS certificate tests

  • :py:func:cheroot._compat.extract_bytes

  • Peercreds lookup

v6.5.3
