+# 3.11.5
+- PHPStan and PHPUnit are now managed as Composer dev dependencies.
+- Core code is now analyzed using PHPStan level 6 (full, including iterable types checking).
+- Improved type information available to PHPStan in many areas.
+- Mass-removal of useless PHPDoc.
+- Fixed incorrect documentation of `Internet::getURL()`, `Internet::postURL()` and `Internet::simpleCurl()`.
+- Fixed crash on use of case-mismatched recursive command aliases.
+- Basic build instructions are now provided in `BUILDING.md`.
+- `build/server-phar.php` now uses GZIP compression on created phars, providing a 75% size reduction.
+- `ClientboundMapItemDataPacket` now uses `MapDecoration` objects for decorations instead of associative arrays.
+- Updated Composer dependencies to get bug fixes in `pocketmine/nbt` and other libraries.
+- Packages `pocketmine/classloader` and `pocketmine/log` are now required; these provide classes previously part of `pocketmine/spl`. This change has no effect on API compatibility.
