This is a list of Java Edition 1.0.0 development versions.
Beta 1.9 Prerelease   is the first pre-release for Java Edition 1.0.0, released on September 22, 2011, which adds nether fortresses, 6 new blocks including nether bricks and some variants, 5 new mobs including villagers, 4 new items including ghast tears, the mushroom island biome and some minor changes.
Initially a pre-release for Beta 1.9, Mojang instead 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.

Unlike the client, the server for this version was not reuploaded.
The original version of the Beta 1.9 Prerelease 3 was released shortly before 14:57 UTC on October 6, and featured a crash issue. The first reupload of Beta 1.9 Prerelease 3 was released at around 14:58 UTC, while the second reupload was released at around 15:08 UTC. One of these reuploads was to remove some code relating to the ender dragon.[which?] This was possibly done to avoid leaking information, as the ender dragon had not yet been announced.

Beta 1.9 Prerelease 4  is the fourth pre-release for Java Edition 1.0.0, released on October 13, 2011, it adds the End dimension, the ender dragon, and moon phases, it also completed the enchanting mechanics, changes fluid placement using buckets, and fixes some bugs.
Beta 1.9 Prerelease 5 is the fifth pre-release for Java Edition 1.0.0, released on October 27, 2011, which adds several new achievements and controls, changes some mobs and the texture of some blocks, and fixes some bugs.
- Several new achievements added.
- Overkill: Deal nine hearts of damage in a single hit

- DIAMONDS!: Acquire diamonds with your iron tools

- The End?: Locate the End
- The End.: Defeat the Ender Dragon
- Local Brewery: Brew a potion
- Into Fire: Relieve a Blaze of its rod
- Return to Sender: Destroy a Ghast with a fireball
- Debug controls (from the pre-re-uploaded version of Beta 1.8 Pre-release):
- F9: Freezes the camera in its current position.
- F6: While also turning back time, enables a strange "bouncy" movement. It locks the player's y coordinate (meaning they cannot jump or fall). It makes the player accelerate relatively slowly when moving. Additionally, the player can also clip into blocks slightly - at a high enough speed, the player can push all the way through a block. Transparent blocks have no clipping whatsoever.
- N and M: Changes the view's rotation clockwise and anti-clockwise, respectively. Hold both keys simultaneously resets the rotation.
- Y and H: Decreases and increases the field of view, respectively. These keys seem to affect the field of view differently to how the FOV option does - the player's hand (or anything the player is holding) will also become stretched as the field of view increases or decreases, which does not happen if the player changes the FOV option in the menu. Holding both keys simultaneously resets the field of view.
- I: Makes the player look up, J looks left, K looks down, and L looks right. These movements are normally done by moving the mouse. This setting cannot be reset by holding any keys simultaneously.
- U and O: Moves the third-person camera forwards and backwards, respectively. This setting cannot be reset by holding both keys simultaneously.
- Scrolling the mouse wheel (which also scrolls the selected slot in the hotbar) rotates the forward, left, right, and back directions.
- In creative mode, using an empty bucket will no longer fill it up when removing fluids with it.
- Fence post selection boxes now resemble their collision boxes.
- Now flowing downwards creates source blocks, instead of flowing water.
- Hostile mobs act neutral in creative mode.
- Entity punch range in creative mode reduced, as a result.
- Now have a new dying animation even though they still do not spawn.
- Their health has been changed to 1 to test this.
- Now spawn on levels 0-40 rather than 0-16, making them much more common.
- The version number once again displays on the top-left of the screen.
