0.0.23a_01 is a version of Java Edition Classic released on July 11, 2009, at 14:35 UTC. It is the last version of Middle Classic. This version is not available in the launcher, but has been archived elsewhere. After this version, Notch changed the version naming system to resemble the one used from 0.24_SURVIVAL_TEST onwards, by which this version would be called "0.23_1" (or "0.23_01"; the actual versions used a zero-padded hotfix number).

Changes

Gameplay

Controls

• Added a keymapping to control render distance.
  • Players can once again press F to toggle render distance.

Remake

To celebrate 10 years of Minecraft, a JavaScript remake of this version was uploaded to the Minecraft website and made it possible to play multiplayer with up to 9 others through the browser. This version can be played at classic.minecraft.net for free.

Trivia

• Notch planned to refactor the version naming system after this version, removing the first zero and the "a", becoming the format "<major version>.<release number>[_<patch number>]". As an example, since this was the most recent version at the time, "0.0.23a_01" would be called "0.23_1" with such a system. However, this version did not actually use this name in-game. Additionally, the numbering that was actually used zero-padded the revision number.
  • This format was also used somewhat in Beta.
• It has previously been rumored that Notch did not use LWJGL for Minecraft until after this version. However, this is a confusion from the fact that he switched from pure Java to LWJGL specifically for a small game he was working on for a game competition during the middle of July 2009, and Minecraft has actually used LWJGL from the very beginning of its development, including the previously unreleased pre-Classic versions.
