Java Edition 13w12~

13w12~ were two debug snapshots for Java Edition 1.5.1 that attempted to fix an issue with the frame rate dropping significantly when using smooth lighting. The first debug snapshot was unsuccessful, however the second debug snapshot was successful in fixing this bug. The first snapshot was released on Mojira as a "temporary snapshot", which is why these snapshots do not follow regular naming conventions.

These snapshots were only released as clients; no corresponding server was released. However, these snapshots share their protocol version number with snapshots 13w09c through 13w11a, meaning that 13w12~ can connect to servers running any of those snapshots.

Fixes

 * 1 bug fixed
 * – FPS drop due to smooth lighting.

Trivia

 * The first upload of this version holds the record for the least amount of changes in a snapshot, changing nothing.
 * The reupload of this version ties the record for the least amount of changes with 20w08a, at one bug fix.
 * This is the only snapshot that breaks the naming convention set by every other snapshot, since it doesn't include a letter at the end of it.
