- Added a number of sound events, but the sound effects are not added yet.
- Added new step sound for silverfish.
- Added three new sound effects for zombies.
- Added new sounds for zombie pigmen.
- Added bat sounds.
- Falling sand now properly “pops” when falling on non-solid blocks (such as torches).
- The redstone repeater lock mechanism is now slightly more stable / predictable. It’s still not 100% as Mojang wants it, but fixing it completely will require bigger changes planned for Minecraft 1.5.

- Updated translation files.
1 bug fixed
