Java Edition 1.0.0/Development versions
This is a list of Java Edition 1.0.0 development versions.
Beta 1.9 Prerelease
Beta 1.9 Prerelease[1][2][3] is the first pre-release for Java Edition 1.0.0, released on September 22, 2011,[4] which adds Nether fortresses, 6 new blocks including Nether bricks and some variants, 5 new mobs including villagers and blazes, 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.

Beta 1.9 Prerelease 5
Beta 1.9 Prerelease 5 is the fifth pre-release for Java Edition 1.0.0, released on October 27, 2011,[20] which adds several new achievements and controls, changes some mobs and the texture of some blocks, and fixes some bugs.
Additions
General
- Several new achievements added.
- Overkill: Deal nine hearts of damage in a single hit
- Enchanter: Use a book, obsidian and diamonds to construct an enchantment table
- Librarian: Build some bookshelves to improve your enchantment table
- DIAMONDS!: Acquire diamonds with your iron tools
- We Need to Go Deeper: Build a portal to the Nether
- The End?: Locate the End
- The End.: Defeat the Ender Dragon
- Local Brewery: Brew a potion
- Into Fire: Relieve a Blaze of its rod

- "The End." achievement is impossible.
- Debug controls (from the pre-re-uploaded version of Beta 1.8 Pre-release):
- F9: Freezes the camera in its current position.
- F6: 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) also becomes 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.

- Added
/toggledownfall.
