Old Alpha

Many historical versions in the Minecraft launcher are labeled 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.
* 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.
