  • The following mobs can not move through Nether Portals on their own, and must be captured with a Capture Net or bucketed and brought through manually. This is being done to prevent mass lag from smaller entities jumping in and out of portals. Despite some of these not moving much, I just went ahead and removed it from all smaller entities as a safety net.

### Note from the author, me, crispytwig :-)

It's definitely been a while, thanks for your patience! Please report any bugs you find in the port and I will try to address them as soon as possible.

With that being said, going forward, updates will likely not be as frequent as they used to, but I will be trying to maintain this more. In the future I'd like to add more animals from the Bedrock version, but I primarily want to focus on compatibility for other mods so I can focus on creating new content.

This version is 1.0.0 _(I know, after 5.0?)_ because it marks the first major update for Naturalist after our Bedrock port, and this will now serve as the baseline for the mod going forward. With that set, I want to properly start putting out things like hotfixes. Thank you again!

  • Removed unused content.
