1.18.x support will be for the most recent stable 1.18 release (for instance, despite 1.18.2 currently having snapshots, if support was to be released today, it'd be for 1.18.1 with 1.18.2 tentatively supported).

Hopefully this wont require too much of a major refactor, and therefor 1.17 and 1.18 support will be able to be maintained simultaneously.
