Java What changed in 13w47e

Everything below is measured by comparing the game files of 13w47d with 13w47e — not copied from patch notes.

Minecraft did not ship a data generator until January 2018, so there is no registry of blocks and items to compare for a build this old. What is below is read from the game’s own client.jar: the text the game displays, and the textures, models and sounds it ships. New blocks and items almost always show up in both.

KeyText
stream.unavailable.archMismatchThe custom java version used to launch Minecraft has a different architecture than the one used to run the launcher. Please make sure these are the same, either 32-bit or 64-bit for both.

Development cycle

This build was part of the run-up to 1.7.3. Everything tested here landed in that release.
