Hi, I'm currently using 1.19.2 until other mods catch up to updating to 1.19.3. That may be a while, so I was wondering if you'd be willing to make the newest updates compatible with all 1.19 versions, or at least 1.19.2

Not possible since 1.19.3 is actually more like 1.20.0, mojang is just stupid and apparently has no idea how version numbers work anymore.
I did however backport the fix to 1.19.2 in v0.10.1
