Hello, today I will explain you the whole history of Minecraft from the cave game tech test to the last classic, 0.30. Beware, it's a list. A long list.
Cave Game Tech Test (Shortened CGTT, often called pre-0.0.0) was the first ever Minecraft version that we know of. It had 2 blocks, grass and cobblestone, and also cave generation. It was made 10.5.2009.
Rd-132211 is a version available in the launcher, provided to Mojang by Ez, the ex-wife of Notch and the first player to play Minecraft other than Notch. It was made 13.5.2009.
Rd-132328 is a version made 13.5.2009. It added the human mob to Minecraft. It is in the launcher.
Rd-20090515 is a version made on 15.5.2009. Not much is known of it, but it possibly added better terrain generation. It is not in the launcher, trying to play it plays another Rd.
Rd-160052 was made on 16.5.2009, and added dirt, stone and wooden planks. It is in the launcher.
Rd-161348 added saplings. It was released on 16.5.2009, 13 hours after Rd-160052. It is playable in the launcher.
Unconfirmed versions mentioned in the irc logs, 15.5.2009:
Mc-161607 made it work in a "applet"
is currently totally unknown.
Mc-161616 changed the mouse code.
Mc-161648 possibly added the version number (0.0.1a)
0.0.2a for sure added the version number.
0.0.3a added caves.
If these versions existed, it would mean that the last Rds were development versions.
The existance of 0.0.5a, 0.0.6a, 0.0.7a and 0.0.8a is completely unknown.
This post will be continued soon with 0.0.9a, that was the first version released for testing.
