This page documents unreleased versions.
While there is proof of these versions' existence, they were never released to the public.
Blog posts and YouTube videos by Notch were posted showing in-development features later included in 0.26 SURVIVAL TEST and later releases.
Performance improvements (October 13, 2009)
- Terrain rendering optimizations make the game render as much as 40% faster.
- However, the pre-rendering code for entities still significantly slows down the game.
Explosions update (October 20, 2009)
Word of Notch post, YouTube video
- Creeper explosions no longer destroy stone or stone-like blocks.
- Explosions leave black smoldering particle effects over the affected area.
- Optimized resource usage by making far-away entities invisible; the distance they are visible in depends on entity size.
- Removed background gradient from GUIs.

Rain test (October 22, 2009)
- Rain
- Dynamic and bounces around.
- Created by pressing F5.[verify]

Dirt slab test (October 22, 2009)
- Half-sized dirt block test.
- Dirt slabs replaced dirt upon generation.
- Slabs caused the tile they are in to be darkened.
- Cannot be climbed or made into double slabs yet.
- You cannot break blocks behind the slabs, as their hitbox is that of a full block.
Rain fix (October 22, 2009)
- Thinner rain.
- Ceilings prevents rain from falling through.
-
Rain in this version, from Notch's blog.
Inventory mockup (October 23, 2009)
- A mockup was made in a graphics editor over the screenshot from the previous post.
Slab progress (October 23, 2009)
Word of Notch post, YouTube video
- Half block nearly finished.
- Dirt is no longer converted to dirt slabs on worldgen.
- The player can now properly climb up slabs.
- No longer cause adjacent blocks to be darkened.
- The top layer of water is now fully bright.

Spider test (October 23, 2009)
Word of Notch post, YouTube video
- Spider test (originally were passive, as seen in the picture by Notch, but were later given a new AI).
- Mushrooms only spawn underground.
- Slabs have a new hitbox, allowing blocks behind them to be broken.[verify]
New blocks (October 23, 2009)
- Mossy cobblestone, TNT, block of iron, bookshelf, and bricks.
- New gold block, gold ore texture.
- Creative inventory may have been temporarily enabled in order to obtain exact numbers of the new blocks (notice the random nature of the blocks placed versus the empty hotbar).
