Hello all,
I've pushed untested support for 1.19. Dev builds are available from Actions runs, hoping to make time to test and draft a release tonight.

Note that this build contains changes slated for v4.2.0, most notably the removal of the player cache. This is largely consistent with old behavior, but due to the new, more reliable viewer tracking, player inventories close when the player exits the server even if offline viewing is allowed. This is actually due to part of the internal logout process and is not triggered by OpenInv. As Spigot has no way to determine why an inventory was closed, I'm not yet sure how we'll handle it.

Full changelog (as of this posting) is here: 4.1.10...866ad3
Untested 4.2.0-SNAPSHOT supporting 1.19 can be obtained from this artifact https://github.com/Jikoo/OpenInv/suites/6831855241/artifacts/263225132

OI is affected by https://hub.spigotmc.org/jira/browse/SPIGOT-7035. Historically this means people will complain about chat spam for the next several months if I don't apply the fix myself. I suppose this is an opportunity to return to supporting CB as the minimum software. Seems like an unnecessary pain, but such is working with NMS.

https://github.com/Jikoo/OpenInv/releases/tag/4.2.0 is now available for those of you who aren't hindered by restrictive hosts. For those of you who are, the build was uploaded to CF and will be available when approved.
