Minecraft wiki entry for Version_formats, associated text: Originally subtitled Pocket Edition, versions in this development phase took the form of a "v" followed by three numbers: phase, major, and minor, followed by the word "alpha". The phase number during Alpha was 0, and the major and minor numbers incremented each release (when the major version number was incremented, the minor version was reset to 0). Development builds in this phase were labeled as their parent version followed by "build" and the build counter. For example, v0.14.0 alpha build 1 was the first build for Alpha version 0.14.0.
