Chase the Skies compatibility!

This update brings:

• Compatibility with 1.21.5 - 1.21.6
• Enhanced API

Bug Fixes:

• Now the uninstall should deactivate the datapack correctly.
• The timer should not be negative if you subtract too much time.

We have a hard time bringing you the updates for all versions from 1.15 to the newest ones, Mojang changes the system a lot and complicates the process, but we have been able to do it just for you, we appreciate very much if you can support us through Ko-fi :)
