+## General
+- `tools/convert-world.php` now writes errors to stderr and sets the proper exit code.
+- Explosions now use the standard mechanism for processing block updates. Previously, it used a special mechanism due to prohibitively poor efficiency of the standard algorithm. Since these inefficiencies have now been addressed, explosions can now be consistent with everything else, with minimal performance impact.
+- Command usage strings are no longer automatically translated (use `Translatable` instead of bare string keys).
+- Command description strings are no longer automatically translated (use `Translatable` instead of bare string keys).
+## Fixes
+- `ItemFactory->isRegistered()` no longer crashes when given negative item IDs.
+- Furnaces now continue to operate after reloading the chunk they were contained in.
+
+## API changes
+- The following API methods have been added:
+  - `Liquid->getMinAdjacentSourcesToFormSource()`: returns how many adjacent source blocks of the same liquid must be present in order for the current block to become a source itself
+  - `Player->getPlayerInfo()`
+- `Liquid` minimum-cost flow calculation code has been extracted to `MinimumCostFlowCalculator`.
