Remake
Main article: Minecraft Classic (JavaScript 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.[7]
Trivia
- Notch planned to refactor the version naming system after this version, removing the second 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.[2] However, this version was never actually given this name outside of this example.
- This format was also used somewhat in Beta.
- Despite being the last Multiplayer test version, Multiplayer is still accessible in late classic until it no longer functions in Indev.
