Old Alpha

Many versions in the Minecraft launcher are labelled as "old_alpha", despite not all actually being from the Alpha development phase (though this may be due to a more general use of the software development term "alpha"). This term may refer to:


 * Pre-classic, the first private development phase of Minecraft.
 * Java Edition pre-Classic mc-161607, called "minecraft alpha" by Notch.
 * Classic, originally named "Minecraft Alpha".
 * Indev, where Minecraft was now "in development".
 * Infdev, infinite world generation development.
 * Alpha, the development phase of Minecraft preceding Beta.
