Java Edition Classic 0.0.13a

0.0.13a was a version of Classic released on May 22, 2009, at 18:34 UTC.

A version called "0.0.13a" is available in the launcher. However, it has many differences from the version called 0.0.13a in 2009, which appeared to support regular terrain, whereas the launcher version strictly uses flat terrain. Additionally, 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. This may mean that the version from the launcher is in fact an early testing version of 0.0.13a solely intended for testing level size, and the release of 0.0.13a remains lost.

Bugs

 * Level saving sometimes does not work.
 * The reason is because Opera and older versions of Java did not support a workaround Notch made to allow connecting to a host from an applet in LWJGL.

 * Despite the surface being flat in the launcher version, caves with lava lakes can still spawn underground.
