Comment:
When updating parso, I looked at jedi but didn't catch the breaking changed introduced in `PosixPath`; I mistakenly assumed the only critical change was a drop in py2 support, which wouldn't matter since we only build it for py3. Sorry for the mistake. The jedi maintainer keeps promising an 0.18.0 release "in a matter of weeks", but it seems to have been delayed by several weeks, so this is the right move now.

Also, `revision=1` is appropriate here. There was never a `python3-parso-0.7.1_1` because I dropped the py3 subpackage from `python-parso` when moving from 0.7.0 to 0.7.1.
