Java Edition Alpha v1.0.0

Alpha v1.0.0 is the first Alpha version of the game, released on June 30, 2010. It was originally labeled as "Minecraft Infdev" at the top left corner while playing in a world; Notch retroactively decided this version would be named Alpha v1.0.0 upon the release of Alpha v1.0.1.

On June 29, 2010, about 19 hours before the official release, there was a downloadable version to test the offline client.

Fixes
