13w39a is the eighth snapshot for Java Edition 1.7.2, released on September 26, 2013.[1] It adds red sand to mesa biomes and allows for more than one enchantment on a book.
The server was reuploaded just over an hour after release.
Additions
Blocks
- Generated on the lowest surface levels of the mesa biome.
- Behaves like normal sand.
- Can be smelted into glass and crafted into TNT, but cannot be crafted into sandstone.
Non-mob entities
- Can only be obtained using
/give @p 422,/give @p hopper_command_blockor/summon MinecartCommandBlock. - Activated by activator rails.
- Run their command every so often as long as they are powered - a command block minecart going across a single powered activator rail at full speed runs its command thrice.
- Can be success-tested while on a detector rail with a redstone comparator next to the rail (just like how the minecart with chest and minecart with hopper can be fill-checked).
Changes
Items
- Can now give multiple enchantments.
World generation
- Orange terracotta generates in place of sandstone, but not in the same type of formation.
General
Logging
- Now done using Log4j 2.
- Default logging location is now in logs/latest.log, older logs are archived in logs/year-months-day-counter.log.gz with GZIP compress. The year is 4 digits, and the month and day are both 2 digits. The counter is the number of startups on the day. The counter is 1 when the first startup of the day and increasing each startup.
- The way logs are saved can be changed, examples: HTML page, database, errors only, no logging at all.

- MC-673 – Sky/lighting doesn't get darker during a thunderstorm.
- MC-1105 – Villagers act like it is raining when they are in the desert, and it rains elsewhere.
- MC-28405 – The saddle equip sound effect does not play when equipping a pig with a saddle.
From the 1.7.2 development versions
