 - Fixed some issues with multiple consecutive commas inside quotes in form responses.
 - Fixed server crash when the manifest json does not contain a json object in a resource pack.
 - Ender pearls no longer collide with blocks that do not have any collision boxes.
+
+# 3.9.6
+- Updated Composer dependencies to their latest versions.
+- Prevent clients repeating the resource pack sequence. This fixes error spam with bugged 1.12 clients.
+- `Internet::simpleCurl()` now includes the PocketMine-MP version in the user-agent string.
+- Spawn protection is now disabled by default in the setup wizard.
+- Default difficulty is now NORMAL(2) instead of EASY(1).
+- Fixed crashing on corrupted world manifest and unsupported world formats.
+- Fixed `/transferserver` being usable without appropriate permissions.
+- `RegionLoader->removeChunk()` now writes the region header as appropriate.
+- Fixed performance issue when loading large regions (bug in header validation).
+- Fixed skin geometry being removed when the JSON contained comments.
+- Added new constants to `EventPacket`.
+- Added encode/decode for `StructureTemplateDataExportRequestPacket` and `StructureTemplateDataExportResponsePacket`.
+- Fixed broken type asserts in `LevelChunkPacket::withCache()` and `ClientCacheMissResponsePacket::create()`.
+- `types\CommandParameter` field `byte1` has been renamed to `flags`.
+- Cleaned up public interface of `AvailableCommandsPacket`, removing fields which exposed details of the encoding scheme.
+- Improved documentation for the following API methods:
+  - `pocketmine\item\Item`:
+    - `addCreativeItem()`
+    - `removeCreativeItem()`
+    - `clearCreativeItems()`
+  - `pocketmine\level\Explosion`:
+    - `explodeA()`
+    - `explodeB()`
+- Fixed various cosmetic documentation inconsistencies in the core and dependencies.
