Why no new release after 2020?

[Bruce Wen]

Now, I started to use Python 3.11

The python-language-server latest version is 0.36.2. It requires jedi<0.18.0,>=0.17.2 and parso<0.8.0,>=0.7.0.
So, I cannot use grammar 311 provided by parso in 2021 (https://github.com/davidhalter/parso/blob/master/parso/python/grammar311.txt).

Anybody knows why no release after 2020?
