The 26.2 Update
We would like to thank everyone that worked on this update:

Changes for server owners
Not too much beyond Vanilla changes! Although as per usual, we recommend updating to the latest version of Paper as we do not backport exploit fixes after a new version has been stable for a while.
You may see a “Missing file: /data/minecraft/game_rules.dat” error in the logs - this is expected and safe to ignore, as it stems from single-player-only logic that doesn’t apply to server worlds.
Reminder: World storage format changes
If you haven’t seen the 26.1 announcement and its world storage format changes yet, you should give it a read: https://papermc.io/news/26-1/
For developers
Beds are no longer block entities
Beds are now regular blocks again, which means they lose the ability to hold a PersistentDataContainer. If you had previously stored important data in a bed’s PDC, you need to listen to the new AsyncServerDataFixerRemoveBlockEntityEvent to save this data elsewhere.
Adventure 5
Paper 26.2 ships with Adventure 5, removing API that was previously deprecated. The two most important changes are to BookMeta, which no longer extends Adventure’s Book interface (use its own pages methods instead of the removed builder), and the removal of deprecated ClickEvent/HoverEvent use.
You can find migration docs here.
Reminder: Versioning change
We have replaced the old -R0.1-SNAPSHOT suffix with a much more informative versioning scheme. See the 26.1 announcement for more information.
