Please note that:
1) Please, backup your full server before upgrading to v2.8.9;
2) Regenerating an island reports the time it took in the serverlog for now.

Changes in 2.8.9:
Version 2.8.9 contains mostly changes under the hood, and updates the biomes in chunk regeneration to use the new 1.16 Nether biomes. The way we hook into Multiverse changed to prevent the watchdog from throwing warnings when booting the server for the first time.

Changes affecting players:
All sign types can now be used as challenge signs.

Please report all the issues you experience in the Discussions-section on the forums or on Github. Include the full server log and possibly a timings report if there are performance issues.
