This article is about publicly-released development versions for the PC. For the stable versions' history, see Version history.

Starting in the period between Beta 1.7.3 and Beta 1.8, Mojang began to publicly release testing versions of full updates in order to get major feedback, especially for bug reporting, so that the official update is considerably more stable. While these versions were public, they were not auto-installed by the game and are completely optional.

In Beta, these versions went under the tag of "Pre-Release", candidates subject to release for 1.0.0 as "RC#", and post-1.0.0 were given a name under a special syntax (see below).

To install a development version, simply download the minecraft.jar file, place "minecraft.jar" in your .minecraft/bin/ directory and run Minecraft as usual. For GNU/Linux, some extra work needs to be done to get the 1.3 snapshots going.

Note: This is not a page for reporting bugs; they should be posted on the relevant Known bugs page instead.

Weekly Snapshots

The format for the snapshots is YYwWWx.[1]

YY is the two-digit year, WW is the two-digit week number within the year, and x is a unique identifier, starting with "a", in case there is more than one release per week, and "w" simply stands for "week".

    • Sometimes when pushing someone off a cliff they do fall - you are not meant to be able to push people as of 12w23a.
    • It appears to be a server-side feature only, yet has not been applied to the client so far, as you can still push mobs or other entities in singleplayer.
    • It also appears to be a PvP-only feature. In SMP, you can still push mobs and entities too.
  • When standing still in the same place as another player the other player glitches about.[4]
  • When the player sleeps in a bed, setting his/her spawnpoint, destroying the bed, dying, and clicking respawn will not reset the spawn point. This is most likely due to a workaround made for the /spawnpoint command.
  • Zombies will not burn in the sun (Really a bug?).
  • Some users experience a layering issue with Chests and Ender Chests where the bottom portion shows through the top portion, appearing bugged[5].
  • You see the block select line through the book of the enchantment table.
  • Leggings are the wrong size for the character model.
  • Sometimes superflat worlds spawn default world chunks.

1.3.1 Pre-release July 30, 2012

  • When a Dragon Egg teleports from being touched to a location not directly touching the ground, it will appear as a Lava source block until settling.[15]

  • Allowed those connected to a player's LAN network to join SP games
    • The player can now use “/publish” to open your single-player game for LAN players to join. This is still very much work in progress, so it lacks some necessary settings such as what game mode players will get, and if they should be able to use cheats or not.

    • Added the /tp command from multiplayer to singleplayer, allowing teleporting between players.
  • The player can now place Levers on the underside of blocks, upside-down.[33]

12w05a[61] February 2, 2012

  • There were actually two versions of this snapshot, and the original version is no longer available. The second version would technically have been 12w05b, but since it was released so soon after the original 12w05a, jeb decided to simply replace 12w05a, and the version released the next day was named 12w05b.[62] The original 12w05a had a bug where the game would crash when right-clicking a sitting cat empty-handed, and it also had some griefing in the translation. It is for these reasons that the snapshot was updated so soon.

Beta 1.9 Pre-releases

Considered the "Lost Update",[72] a full version under the name "Beta 1.9" never came. Instead, Mojang opted to delay the release of this update until MineCon 2011 and release it under the name "Minecraft 1.0.0". This decision was made after a few development versions tagged as Beta 1.9 were already sent out, so the name Beta 1.9 was kept for all of the development versions in the gap between Beta 1.8.1 and Minecraft 1.0.0, other than the Release Candidates.
