+# 3.9.4
+- Fixed a memory leak when scheduled updates were pending on a chunk being unloaded.
+- Fixed plugin detection in crashdumps. Previously `src/pocketmine` anywhere in the path would cause the error to be considered a core crash, regardless of the preceding path.
+- Fixed entity metadata types for 1.12. The SLOT type was removed and a COMPOUND_TAG type added. This change involves changes to internal API which may break plugins. **See the warning at the top of this changelog about API versioning.**
+- Fixed random and base populator amounts of trees and tallgrass never being initialized. This bug had no obvious effect, but may have become a problem in future PHP versions.
+- The following internal methods have been marked as `@deprecated` and documentation warnings added:
+  - `Entity->getBlocksAround()`
+  - `Entity->despawnFrom()`
+  - `Entity->despawnFromAll()`
+- Fixed plugin `softdepend` not influencing load order when a soft-depended plugin had an unresolved soft dependency of its own.
+- Fixed endless falling of sand on top of fences.
