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.

 * The terrain is no longer always a full block above water.
 * Lava on top of water will always produce stone
 * The block being used is once again shown in the top right corner
 * The world generating screen now shows darker dirt.

Bugs

 * Transparency issue with water.
 * Water does not work outside the map.
 * 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.

Differences between 0.0.13a-launcher and the original

 * The world is originally square and only becomes long when a new level is generated. The original has normal terrain.
 * Despite the surface being flat, caves with lava lakes can still spawn underground.
 * The Generating Level screen shows lighter dirt in the launcher version. This is left over from 0.0.12a_03.
 * The launcher version has other features left over from 0.0.12a
