CommitFest 2017-09 - How do I know what commit to apply patches to

Hello PostgreSQL hackers,

I was diving into CommitFest 2017-09 <https://commitfest.postgresql.org/14/>
to help review some patches, but I was not sure which version / git commit
/ git tag of the PostgreSQL repo I should be checked out to in order to
correctly apply / test these patches. Is there a place within the
CommitFest where it says what version to have checked out?

Thank you,
Ryan
