[Twisted-Python] Twisted 21.2.0rc1 Release Candidate Announcement

[Craig Rodrigues]

It's time for another Twisted release!

There are two major announcements for this release:

- *Python 2.7 support has been dropped*.  Twisted 21.2.0 supports Python
3.5 and higher only
- *This will be the last Twisted release to support Python 3.5*.

Twisted 21.2.0rc1 brings the following:
- twist dns --pyzone now works on Python 3
- twisted.web.twcgi now works on Python 3
- all tests pass on all platforms on Python 3.8, including asyncio tests on
Windows
- tests pass on Python 3.9 (thanks to Michał Górny)
- type hints, as specified in PEP 484, are now used in functions throughout
the codebase
- mypy (static type checker) is now run over the codebase during CI to help
detect problems, and help improve the use of types
- code in is now formatted with Black (thanks to Tom Most)
- many CI and automation improvements (thanks to Adi Roiban and Thomas
Grainger)
- many more fixes (225 tickets closed!)


You can install by running this command:

  python -m pip install Twisted==21.2.0rc1

The full tarball is available at:
https://pypi.org/project/Twisted/21.2.0rc1/#files

The full NEWS file with all changes is at:

Please test it, and let me know how your applications fare, good or bad!
If nothing comes up, 21.2 will release very soon.

[Twisted-Python] Release instructions: `tox -e towncrier` does not work?

[Craig Rodrigues]

In
https://github.com/twisted/twisted/commit/0ad24679b168370bf0d695825170a7532bf0698f#diff-4fd162cb9fc2878b140dcc9d9d364f9f60d404a76ebda2c10518810ffe63852dL115

Adi Roiban changed one of the steps the release documentation to run a
command:

*tox -e towncrier*

but that tox target does not exist.

Does Adi or someone else have that tox target in a patch lying
around somewhere?

For now I can manually run *towncrier *manually outside of tox.

[Twisted-Python] Release blocker: Use latest pydoctor release ?

[Craig Rodrigues]

Hi,

This ticket: Use latest pydoctor release,
https://twistedmatrix.com/trac/ticket/10068

is marked as a release blocker.

Has that been resolved or is there more work that needs to be done to fix that?
