Yes, please do this

indeed. keep releases on modrinth up to date.

I've already switched to zoomify but I would gladly switch back to logical zoom if it was updates were maintained on there

The build for 1.19.1 is now on Modrinth. There was a bug which prevented the 1.19 version being published. It's here: https://modrinth.com/mod/logical-zoom
