Alpha v1.0.0 is the first Alpha version of the game, released on June 30, 2010.[1] It was the second of two versions released on June 30, 2010, and was labeled "Minecraft Infdev";[2][3] Notch retroactively decided this version would be named Alpha v1.0.0 upon the release of Alpha v1.0.1.[4]

On June 29, 2010, about 19 hours before the official release, there was a downloadable version to test the offline client.[5]
