Who wants to cut the release? I'm happy to do so later today, if no one else intends to. :)

[pradyunsg]

Let's also include #344, and then I'll cut the release. :)

[di]

#344 has been merged, thanks!

[pradyunsg]

ACK. I'll make a release sometime this week. :)

[mattip]

@pradyunsg ping?

[yoav-orca]

@pradyunsg do you plan to release soon?

[di]

I think Pradyun is probably pretty busy with the upcoming pip release, and I doubt additional notifications from this issue is going to help.

Might be time to add some release automation via https://github.com/pypa/gh-action-pypi-publish to make this process simpler in the future.

[pradyunsg]

I'll come around to this this week -- I plan to include this in the upcoming pip release too. :)

[brettcannon]

@di see #339. 😁

[pradyunsg]

It's up! https://pypi.org/project/packaging/20.5/

Now, to update pip's vendoring and prepare for pip 20.3! :)
