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.

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".

Notable Bugs: (Complete bug list)

  • Big Trees, Birches and Pines spawn only very rarely (a rare example can be found in seed "12w08a", a pine will appear at x and z coordinates 300).

  • Fixed crash when mobs were spawned above block 255.

Notable Bugs: (Complete bug list)

  • max-build-height in the server.properties file doesn't exactly correspond to the real height limit when playing. For example, setting it to 200 will allow players to build until the level 208. So 248 is sufficient to limit it to 256.
  • When higher than the render distance, one can see the sun below at midnight.
  • In SMP, hearts do not appear above Villagers when they are in "Love Mode" and try to repopulate a village.

  • Jungle Leaves seem to drop very few saplings (SSP, untested in SMP) (Bug?)
  • Lit Redstone Lamp block drops when mining a powered redstone lamp. Does not stack with normal unlit Redstone Lamp Block.

  • Pickaxes enchanted with Silk Touch no longer cause Glass to drop itself when broken. (Bug?).
  • Taiga biomes do not spawn trees anymore.
  • Swamp biomes spawn very few trees.

    • Wolves won't always follow the player after being tamed.

12w05a[20] 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. [21] 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.

12w04a[23] January 26, 2012

Notable Bugs: (Complete bug list)

  • Cats, Ocelots, Zombies, Wolves, and Skeletons that get on non-full-height blocks will spin in circles.
  • Ocelots become stuck in fences when they run into them.
  • Zombies will sometimes stand still and track you only with their eyes.
  • Visible lines between rows of blocks.
  • A thrown Bottle o' Enchanting in SMP will not appear.

  • The left side of most mobs' heads will change to white when taking damage.
  • The left side of a Creeper's head does not have light effects applied to it. (Noticeable under light level 7.)
  • Zombies and Skeletons don't know the difference between water and lava when attempting to avoid sunlight. This is probably due to them only attempting to go to areas with low skylight levels, of which both water and lava have.
  • A fire charge that is shot from a dispenser into water will not go out, making fire be possible underwater.
  • Even when it's raining, zombies and skeletons will still occasionally attempt to avoid sunlight.
  • World generates floating chunks.

12w03a[24] January 19, 2012

Notable Bugs: (Complete bug list)

  • In the inventory screen, the player's head will face different directions depending on which way the player is facing in-game.
  • Zombies nearly always spin on axis when unable to reach the player.
  • Jungle Biomes seem to put much more strain on the GL rendering engine, causing low framerates and out of memory errors.
  • Some leaves generated as part of Jungle Biomes will begin to decay immediately, as they are outside the required range of any wood needed.
  • The saplings dropped from jungle tree leaves have the same sprite as the normal oak tree saplings and don't grow a jungle tree but an oak tree.
  • The height of a Wolf's tail being used to gauge health is broken.
  • Attempting to feed a Wolf with any meat will both heal them and put them in love mode.
  • Some torches in the stronghold libraries will not correctly align with the chandelier (being one block off).
  • Wolves attack Creepers.
  • Some entities will at times act as if they are not present, even though they are. They cannot be interacted with, and clicking on them will cause things behind them to activate, as if they weren't there. These are not the same as the "ghost entities" bug that existed previously, as the entities in question are actually there and can often be interacted with both before and after this bug is observed.

Beta 1.9 Pre-releases

Considered the "Lost Update",[30] 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.
