Release 7.0.18

* Synchronize YamlRegionFile#saveAll

This prevents multiple invocations of the method from intersecting, which could potentially cause the .tmp file to be overwritten before being renamed, thus corrupting the region storage

* Synchronize on the class instead of the instance

I didn't realize it before, but it looks like there is at least one instance of YamlRegionFile per world, so synchronizing on the instance wouldn't necessarily help.

 # Changelog
 
+## 7.0.18
+
+* Add lava-harden flag for cobblestone/stone/obsidian/basalt forming.
+* Replace PigZapEvent on Paper to avoid startup warnings.
+* Avoid unnecessary NPC checks to improve performance in some situations.
+* Filtered "multiple regions" messages in commands to only show regions that the player has permission to use the command on.
+* Fixed potential corruption that can occur in extreme region / slow hardware setups where it hasn't finished saving by the next save attempt.
+
+## 7.0.17
+
+* Fix cocoa not being treated as a crop in relevant flags.
+* Fix overlapping game mode flags sometimes not storing the expected previous game mode.
+* Replace PaperLib functionality that doesn't behave as expected on MC 26.1+.
+
+## 7.0.16
+
+* Update to 1.21.11.
+* Added experimental Folia support.
+* Workaround an issue where some item/block names aren't adequately translated by the client.
+* Workaround a duplication bug in Paper.
+
+## 7.0.15
+
+* Update to 1.21.10
+* Improve region file loading compatibility with NIO Java APIs
+
+## 7.0.14
+
+* Update to 1.21.5
+* Fix hopper minecarts not being able to take items from containers in protected regions.
+* Fix hopper minecarts not being able to take items from other hopper minecarts in protected regions.
+* Fix non-members being able to leash boats in protected regions.
+* Use new knockback event on Paper servers to better handle mace knockback in pvp and some other knockback situations.
+
+## 7.0.13
+
+* Update to 1.21.4
+* Remove max-stack-size bypass in stack command
+* Fix a falling block metadata leak. (May still be problematic on Spigot, use Paper.)
+* Fix flame enchant being blocked as entity damage on the arrow itself.
+* More Paper-specific performance enhancements for hoppers.
+* Fix block-windcharge-explosions config option not doing anything.
+* Improvements to fishing rod protection.
+* More aggressive vehicle protection (vehicle-destroy now needs to be allowed for various non-destructive damage).
+* Move decorated pot usage from interact to chest-access.
+
+## 7.0.12
+
+* Fix a change in the default behavior of explosion flag handling.
+
+## 7.0.11
+
+* Add support for MC 1.21.
+* Add wind-charge-burst flag which is checked along with `use` (for the interaction) or `pvp` (for the knockback).
+* Add breeze-charge-explosion flag for breeze charges (i.e. from the mob, not player wind charges).
+* Add moisture-change flag and config options.
+* Fix an error if a player logged in to an unloaded world.
+* Fix chest boat usage always being counted as ride.
+* Consider potions thrown by mobs as mob-damage.
+* Workaround spigot no longer sending block change events when a book is placed on a lectern.
+* Improve accuracy of target blocks in blacklist/build-perms events.
+
 ## 7.0.10
 
 * Add support for MC 1.20.5 and 1.20.6, drop support for other 1.20 versions
