YES YES YES! Finally, good chats!
Fixed:
    Chat history and much better chat editing
    A few new decoration blocks
    “Back” and “Quit” buttons to OutOfMemoryScreen
    Made cats more realistic (read: probably annoying). I hope it’s enough to cancel out any joy you may receive from the previous feature!
    Added a “minimal” debug menu for testing with. Shift+F3 to hide the graphs.
    Made placing half blocks on existing half blocks (to make a full block) easier
    Limit framerate on menu screens, no longer uses 100% cpu and make my computer melt
    Fixed fatal crash for converted worlds to anvil, when there’s blocks at max height
    Fixed an old bug with signs clearing text while you’re editing them in SMP
    Fixed crash when logging in while there are blocks at maxheight at spawn
    Fixed TNT ghosts in multiplayer
    Fixed storage minecarts dropping enchanted items
    Fixed crashes on invalid server addresses when joining a server
    Fixed entities being uninteractable if they existed at login (Multiplayer)
    Fixed dupe exploit with paintings
    Fixed furnaces and dispensers dropping enchanted items
    Fixed the “flickering” of chat as it vanishes off the screen
    Fixed text rendering over items in the container screens
    Fixed exploit with jungle saplings (turns other saplings into jungle ones)
    Fixed launcher opening minecraft dir if the path contains a space
    Fixed an off-by-one lighting bug
    Fixed block transmuting (turning one block into another via pistons)
    Fixed placing mushrooms in daylight, where they can’t survive
    Fixed redstone lamps dropping powered block items when destroyed while on
    “save-all” (server) now works even when you have toggled “save-off”
    Fixed turning half-blocks into full-blocks while you’re standing on them
    Fixed seed displaying in F3 debug when the seed is unknown (multiplayer)
    Fixed villager texture changing clientside per profession
    Fixed falling off ledge corners while holding shift
