+# 5.39.3
+Released 27th January 2026.
+
+## Fixes
+- Character limit for writable books has been raised to 512 to accommodate vanilla oddities. (@Gaprix)
+- Fixed `Player->isSneakPressed()` not updating correctly when releasing the sneak key while in forced-crouch state. (@leolee3914)
+- Fixed `ZippedResourcePack` not validating manifest header UUIDs, fixing incorrect crash attribution on `PlayerResourcePackOfferEvent` (and if plugins used reflection on `ResourcePackManager`, which they really shouldn't be - use the provided APIs!). (@dktapps)
+- Fixed biomes not being set in `flat` world generation. (@remminiscent)
+- Fixed key validation for self-signed authentication JWTs. (@dktapps)
+- Fixed query interface incorrectly rejecting tokens if the expected token was negative. (@NopeNotDark)
+
+## Documentation
+- Added information about PHPStan and PHPUnit to contributing guidelines to assist new contributors. (@dktapps)
+- Crash reporting is now properly disabled on GitHub Actions runners. (@dktapps)
+- The `SECURITY.md` file now recommends submitting a private report on the GitHub repository's Security tab. The security email inbox should only be used if you're unable to use GitHub. (@dktapps)
