&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;A couple of development versions of 0.0.12a were developed between May 18 and May 19, 2009. &lt;br /&gt;

===Additions===&lt;br /&gt;
* Server development started.&lt;br /&gt;
** Added basic code such as handling basic client connections and message sending.&lt;br /&gt;
&lt;br /&gt;
===Trivia===&lt;br /&gt;
* The version number is still &amp;quot;0.0.11a&amp;quot;.&lt;br /&gt;
* There are no known gameplay differences between this version and [[Minecraft:Java Edition Classic 0.0.11a|0.0.11a]].&lt;br /&gt;
* This version is available in the launcher, mislabeled as &amp;quot;c0.0.11a&amp;quot;.&lt;br /&gt;
** It was added to the launcher along with several other versions on August 6, 2013.&lt;br /&gt;

{{Unreleased version|section=1}}&lt;br /&gt;
[[File:0.0.12a-dev2.png|thumb|right]]&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;[https://web.archive.org/web/20110302000432/https://notch.tumblr.com/post/109669296/ok-multiplayer-was-boring-but-heres-water Word of Notch post]&amp;#039;&amp;#039;&amp;#039;, &amp;#039;&amp;#039;&amp;#039;[https://www.youtube.com/watch?v=jwgXo3LYKaU YouTube video (reupload)]&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Additions&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
** [[Minecraft:Bedrock]]&lt;br /&gt;
*** Unobtainable to the [[Minecraft:player]].&lt;br /&gt;
*** Cannot be broken, placed against or otherwise selected.&lt;br /&gt;
*** Surrounds the map on all four sides two blocks below ocean level, and also the bottom of the world.&lt;br /&gt;
** [[Minecraft:Water]]&lt;br /&gt;
*** It was originally opaque, rendered as a full block and on the same layer as all other blocks (meaning it had shadows).&lt;br /&gt;
*** The player can swim in it, but mobs move under it at full speed. Swimming underwater was fast at first, as seen in the video. &lt;br /&gt;
*** Spreads from the world border on world generation to fill any empty space next to it. &lt;br /&gt;
** World border&lt;br /&gt;
*** An infinite ocean and invisible barrier now surrounds the map, making it impossible to fall off the world.&lt;br /&gt;
** Pressing F now cycles between four levels of render distance. &lt;br /&gt;
** Pressing N generates a new level, but without a level generation screen.{{Verify|couldn&amp;#039;t find anything about this in the IRC logs}} Mobs also don&amp;#039;t spawn on level reset. &lt;br /&gt;
* &amp;#039;&amp;#039;&amp;#039;Changes&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
** New terrain generator&lt;br /&gt;
*** Terrain is more messy, with more bumps visible on the surface.&lt;br /&gt;
*** Terrain now generates in islands. &lt;br /&gt;
*** No blocks can generate on ocean level, the terrain is always one block above it.&lt;br /&gt;
*** Dirt with access to sunlight will not become grass block upon world generation if below ocean level.&lt;br /&gt;
&lt;br /&gt;
=== Trivia ===&lt;br /&gt;
* Water was made transparent before the release of [[Minecraft:Java Edition Classic 0.0.12a|0.0.12a]]. To do this, Notch had to make it render on a new layer, which is why it lost its shadows. Water would stay without shadows until the release of [[Minecraft:Java Edition Classic 0.0.14a 08|0.0.14a_08]]. &lt;br /&gt;
* The terrain generation source files for this version can be found in the 0.0.13a jar provided in the launcher. When ported to [[Minecraft:Java Edition Classic 0.0.13a|0.0.13a]], it is possible to see how the terrain worked. There are variables to enable/disable the water spreading from the borders, the uniform dirt layer, and blocks being able to generate on ocean level.&lt;br /&gt;
&lt;br /&gt;
== Lava test (May 19, 2009) ==&lt;br /&gt;
{{Unreleased version|section=1}}&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;[https://web.archive.org/web/20200217031836/https://notch.tumblr.com/post/110143855/lava-it-flows-its-very-uncommon-on-the-surface Word of Notch post]&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
[[File:Classic 0.0.12a.jpg|thumb|right]]&lt;br /&gt;
&lt;br /&gt;
* [[Minecraft:Lava]]&lt;br /&gt;
** Translucent.&lt;br /&gt;
** Added shortly before the full release of [[Minecraft:Java Edition Classic 0.0.12a|0.0.12a]], as the screenshot of it posted on Notch&amp;#039;s blog is from May 19th, 2009 at 21:09 UTC (an hour and a half before the version was released).&lt;br /&gt;
* [[Minecraft:Water]]&lt;br /&gt;
** Is now translucent and no longer renders as a full block.&lt;br /&gt;
** Now generates within the world instead of spreading from the world border upon the world&amp;#039;s creation.&lt;br /&gt;
