 # Changelog
 
+## 7.0.8
+* Add support for MC 1.19
+* Add skulk-growth flag and config option
+* Add copper-fade flag
+* Add data packs to report output
+* Add protection for allay inventory slot
+* Categorize allay item pickups under item-pickup flag
+* Categorize dragon egg interaction (teleporting) as building
+* Ignore most NPC-based actions for Player events
+* Optimize handling of tamed animals where the owner was offline (Paper only)
+* Optimize additional InventoryHolder accesses (Paper only)
+* Fix an exception that occurred when plugins created portals with non-player entities
+* Fix possible error when using Paper's entity origin API
+* Update bstats and squirrelid libs
+
+## 7.0.7
+* Add rock-growth flag for budding amethyst and pointed dripstone.
+* Add /rg migrateheights command. See https://worldguard.enginehub.org/en/latest/regions/commands/#migrate-region-heights
+* Add regions.set-parent-on-claim config (set to a region id for /rg claim to automatically assign the parent region).
+* Add `-i search` and `-s` flags to /rg list, -c to /rg teleport.
+* Fix an error in blacklist logging caused by non-player actions (eg on-dispense)
+* Treat unknown causes as known if using paper-entity-origin config option.
+* Improve lightning strike handling from channeling tridents (PaperMC only).
+* Ignore an error caused by lingering player references of offline players.
+* Add red sand to no-physics-sand.
+* Fix potion splash events being cancelled if no entities were affected.
+
+## 7.0.6
+
+* Add support for 1.17 blocks/items, drop support for 1.16.
+* Add use-dripleaf flag for "toggling" big dripleaf blocks.
+* Fix support for fully negative-height regions.
+* Fix crop-growth config option.
+* Be more rigorous with protecting blocks against dispenser behaviors.
+* Fix handling of lingering splash potion effects.
+* Handle other-explosion flag consistently for block-like entities (armor frames etc.)
+* Allow inheriting values for all flags (previously wasn't used for things like teleport.)
+* Region commands that defaulted to the region the player was standing in no longer check parents.
+* Fix child regions being unlinked when redefining a parent region.
+
+## 7.0.5
+
+* Add a use-anvil flag and exclude it from the use flag (since they can break on use.)
+* Add nonplayer-protection-domains flag which allows merging region borders from the perspective of pistons, saplings, etc.
+* Expand crop-related options (crop-growth, etc) to sweet berry bushes, nether wart, and bamboo.
+* Add a config option (`mobs.block-vehicle-entry`) to prevent non-players from entering vehicles.
+* Add a UUID flag (for developers/API usage).
+* Add map query methods with fallback flag (for developers/API usage).
+* Add `on` and `off` optional arguments for `/rg toggle-bypass` command.
+* Add additional timings info for session handlers.
+* Fix sponge-simulation clearing NBT from blocks. Note that if you are using sponge simulation you should switch to something like CraftBook as the feature will be removed from WorldGuard in a future (major) version.
+* Fix the `/rg` command showing up as unknown client-side to players without bypass perms.
+* Fix error propagation from third-party flag loading causing WG to error.
+* Fix a (harmless) exception that occurred when swapping armor slots to the offhand slot.
+* Fix empty lines being sent on enderpearl/chorus-fruit teleport if the deny messages were empty.
+* Fix an issue with falling blocks when using max-priority-association.
+* Fix performance issues with third-party plugins querying protection for offline players.
+* Fix dispensing shulkers over region boundaries.
+* Fix iron door interaction being denied as if it were a regular door.
+* Fix being able to enter/exit regions with the flag denied by using entity mounting functions in other plugins.
+
 ## 7.0.4 (including beta1)
 
 * Add support for MC 1.16. Dropped support for previous versions.
@@ -13,6 +74,7 @@
 * Fix ride flag being checked on striders that didn't have saddles.
 * Add config option to have /rg bypass toggled off on login.
 * Developer changes: Methods taking names in Domains are now explicitly deprecated (was previously just a javadoc comment.); These will eventually be removed: there is no reason to use names over UUIDs. Offline players and NPCs alike have stable UUIDs.
+* Also for developers; The new `com.sk89q.worldguard.protection.util.WorldEditRegionConverter` class has some useful static methods to convert to and from WorldEdit's Region and WorldGuard's ProtectedRegion classes.

+Compiling
+=========
+
+You can compile WorldGuard as long as you have some version of Java greater than or equal to 17 installed. Gradle will download JDK 17 specifically if needed,
+but it needs some version of Java to bootstrap from.
+
+Note that if you have JRE 17 installed, Gradle will currently attempt to use that to compile, which will not work. It is easiest to uninstall JRE 16 and
+replace it with JDK 17.
+
+The build process uses Gradle, which you do *not* need to download. WorldGuard is a multi-module project with three modules:
+
+* `worldguard-core` contains the WorldGuard API
+* `worldguard-bukkit` is the Bukkit plugin
+* `worldguard-libs` contains library relocations
+
+## To compile...
+
+### On Windows
+
+1. **Shift** + **right click** the folder with WorldGuard's files and click "Open PowerShell window here".
+2. `gradlew build`
+
+### On Linux, BSD, or Mac OS X
+
+1. In your terminal, navigate to the folder with WorldGuard's files (`cd /folder/of/worldguard/files`)
+2. `./gradlew build`
+
+## Then you will find...
+
+You will find:
+
+* The core WorldGuard API in **worldguard-core/build/libs**
+* WorldGuard for Bukkit in **worldguard-bukkit/build/libs**
+
+If you want to use WorldGuard, use the `-dist` version.
+
+(The -dist version includes WorldGuard + necessary libraries.)
+
+## Other commands
+
+* `gradlew idea` will generate an [IntelliJ IDEA](http://www.jetbrains.com/idea/) module for each folder.
+* `gradlew eclipse` will generate an [Eclipse](https://www.eclipse.org/downloads/) project for each folder.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
+#       Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+#       and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+#       see the in-line comments for details.
+#
+#       There are tweaks for specific operating systems such as AIX, CygWin,
+#       Darwin, MinGW, and NonStop.
+#
+#   (3) This script is generated from the Groovy template
+#       https://github.com/gradle/gradle/blob/HEAD/subprojects/plugins/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+#       within the Gradle project.
