Added support for lattice blocks to connect vertically with specific blocks other than fence (including themselves)
Fixed torch placement on lattices by adding some "isSideSolid" support
Made pickaxe effective on rails
Fixed rails to be placed on lattice
Added Endermen
No special spawn rules, same as zombie, skeleton, and creepers
Damaged by water
Teleport away from sunlight
Attacks when looked at (unless creative mode), or when attacked first
5% chance of spawning with End Stone block
Won't attack from being looked at while carrying End Stone, until after it's placed
Can have block moving disabled on options GUI, or disable Endermen altogether
Added End Stone
Can spread to adjacent blocks when placed by Endermen
Only spreads at night
Only spreads to unobstructed neighboring grass, dirt, gravel, or sand
Emits particles until spread capability is expended (when metadata = 0)
Spread can be disabled in options GUI
Fixed MCP to target Java 6
Removed restrictions on where fence can be placed
Added saving whether you're in creative/flight/god mode
Allowed torches to be placed on fences
Prevented mouse click from carrying over into game when exiting menus
Changed texture on back of dual furnace to connect
Made fence connect to solid blocks
Added wooden lattice blocks, interconnectable with fence, recipe is like the fence but turned vertically
Added ability to specify item damage after item count in /give command
Made bow shoot infinite arrows when in creative mode
Made F3 debug screen toggle on/off rather than holding it
Reworked mob spawner internals a bit, and gave them a GUI if you're in creative mode
Made axe work on fence and lattice
Added /killall command, kills all entities within the specified radius, 8 blocks by default
Added dual furnace, create by right-clicking a side of a furnace while holding another
Added furnace recipe: iron ingot + redstone = redstone-infused ingot
Added furnace recipe: cobblestone + redstone = redstone-infused cobblestone (has no purpose, mostly a test block)
Avoid crash on player load for items that don't exist
Added ambient occlusion to block rendering (aka "smooth lighting", isn't perfect, can be disabled in options)
Fixed rendering of grass block as item

Prevented map toggle from activating when a GUI is active
Made mobs not attack you in creative mode
Fixed render brightness of inside of hopper to account for light level
Added crafting recipe guide to crafting table GUI, click edge of GUI to slide out
Reduced mob reach similar to later versions, particularly useful for zombies
Added rudimentary (and incomplete) minimap, toggle with M
Adapted beta's leaf decay since Mojang disabled alpha's due to a loop bug
Added "/tp [x] [y] [z]" command to teleport, substitute a coordinate with a non-numeric value to keep the current one
Made pickaxe effective against bricks
