- Added a button for the scheduler editor to the koth editor.
- Some fixes.

- Some compatibility fixes for <1.20.4 version.

- More fixes to make modelengine compatible. (hopefully the last one)

- Fixed a bunch of reported issues (and fixed modelengine support)

- Fixed signs not working
- Fixed villager guis not working.
- Note: ModelEngine is currently incompatible with this version of the plugin. If you are using it, please consider using the last version before the 1.21.5 support or wait a few days until we fix it!

- Added 1.21.5 support. (supported versions: https://docs.artillex-studios.com/supported-versions.html)
- Important: There are some major internal changes to our core api, (AxAPI) so there might be some issues. Please report any unexcepted behaviour at https://github.com/Artillex-Studios/Issues/
- Fixed placeholder issues with score koths & now the timeLeft placeholder works again in the capture koth start message.

- The plugin now requires 1.20 or a newer version. + There is no 1.21.5 support just yet (more info: https://docs.artillex-studios.com/supported-versions.html)

- Fixed that the /koth stop command sent the "koth ended" webhook twice.

- The scheduler editor is back and has been fully rewritten! It is now available with the /axkoth schedulers command.
- We have also created an in-depth tutorial on how to use schedulers, hopefully this helps everyone who had difficulties with it. Check it out here: https://docs.artillex-studios.com/axkoth-creating-schedulers.html

- Added 1.21.4 support
- Fixed some issues with commands on 1.21+ versions
- Improved the throughput of the packet entity system by a large margin (faster holograms)
