Bug fixes

• Fixed a flaw where internally unhandled exceptions could crash the
  worker threads and eventually starve the server of its processing
  resources. It is no longer and issue and the unhandled errors are
  now logged and suppressed except for a few expected exceptions that
  are used for normal interruption requests.

• Fixed compatibility with Python 3.8 in the built-in TLS adapter that
  relies on :pypython:ssl.

  Modern Python versions communicate specialized exceptions
  :pyssl.SSLEOFError and :pyssl.SSLZeroReturnError where the older
  versions errored out in a very generic way.

  These news snippets can link one or more issues or pull requests,
  and be of one or more of the following categories:

  • bugfix: A bug fix for something we deemed an improper
    undesired behavior that got corrected in the release to match
    pre-agreed expectations.
  • feature: A new behavior, public APIs. That sort of stuff.
  • deprecation: A declaration of future API removals and breaking
    changes in behavior.
  • breaking: When something public gets removed in a breaking
    way. Could be deprecated in an earlier release.
  • doc: Notable updates to the documentation structure or build
    process.
  • packaging: Notes for downstreams about unobvious side effects
    and tooling. Changes in the test invocation considerations and
    runtime assumptions.
  • contrib: Stuff that affects the contributor experience. e.g.
    Running tests, building the docs, setting up the development
    environment.
  • misc: Changes that are hard to assign to any of the above
    categories.

Contributor-facing changes

• Started type-checking the project with MyPy against a range of
  versions instead of just one — Python 3.8–3.12 -- by @webknjaz.

  Related commits on GitHub:

• The project how has a .git-blame-ignore-revs letting GitHub know
  which auto-formatting revisions to ignore. It is also possible to
  integrate it locally, if one wants to do so.

• The project adopted the autopep8 tool to assist with automatic
  code formatting. It is chosen over black because it is less
  intrusive which is important to the maintainer as it promotes
  inclusivity. autopep8 is integrated into the pre-commit check
  runner and is configured to only correct 8 violations, avoiding
  changes to compliant snippets.
