0.0.13a[1] is a version of Java Edition Classic released on May 22, 2009 at 17:42, which added level saving for players with accounts and made changes.[2][3][note 1] This version is not archived or available in the launcher.
An early development version of 0.0.13a, mislabelled as its released counterpart, is available in the launcher. It was used for testing the world size, and can only generate flat terrain, instead of the actual terrain used in the full release. Many features from 0.0.12a are still present, such as using the "generating level" screen from that version instead of the one from 0.0.13a.
