Notch: Ok, I'll be mature (= boring) and finish 1.5 first. But I'm going home the second it's out.

I am very excited by this release, as rumors of powered track boosters have been rampant., but... I assume Broonie will not immediately upgrade to 1.5 when its released? He will probably want to try 1.5 on his test system to make sure the protection and Moderator plugins all still work before pushing the upgrade to the live server.

So, I'm not going to immediately update minecraft till I know CF|UK has updated the server, as updating wipes out previous versions.

Also, I highly recommend everyone backup their existing minecraft folder prior to the update. It can be found on Win7 systems in the %appdata% path:

C:\Users\[username]\AppData\Roaming\.minecraft

I am excited for the update not because of those track system but for weather (maybe broonie will not install that or something) ! piston ! and also ACHIEVEMENTS !

I cant wait
It will make weather and ive always wanted to be a storm chaser
Plus easy to get vook porkchop from zapped pigs

PEESTAANZZ!!! AAAGh!!!! fdF!!!

Seriously. Pistons. omfg.

Wait, is pistons coming already? I thought that wasn't until a later update. And weather? Bah! It'll probably cause more lag than it'd be wroth.

Oh yeah...I remember now. He said it wouldn't' be in time for 1.5 but hopes for at least the exit of Beta on 11/11

Whenever I hear pistons, I imagine a bunch of glass tubes running throughout the server.
Beam me up Scotty!

its OUT

Not too bad, it doesn't keep track of what you have done though, ie. you need to chop down a tree. Lol.

In other words, we're going to have messages popping up each time we cut a tree?

No, only the first time you cut a tree after the update.

I'll bet there's going to be loads of bugs for SMP.

This update will NOT have pistons. In fact, they are only 'in talks' with the guy who made the pistions mod. Nothing has been set in stone yet. However, the current update does have weather, and also the ability to have pigs get turned to zombie pigmen when struck by lightning, as well as pigs drop cooked pork if they are on fire when they die. Also, many other smaller things, like achievements (bleh), powered tracks/detectors (yay), and various tweeks to performance and video interface scaling. Also, and this is probably the one I'm most excited about, holding shift while clicking an item/stack in a chest or dispenser moves it instantly to your inventory, and the reverse is true as well. I can't tell you how many times I've wanted to move a storage chest and thought "oh hell no" at the thought of all that dragging/dropping. I do enough of that in the game already. This should relieve some of that mouse hand fatigue.

No, it will not. I cried quietly to myself when I found this out. Then found this out:

1.5_02 (Server only update)
April 20, 2011
Bug Fixes:

• Game no longer crashes from "internal server error" created by bugs in 1.5_01's Server in SMP
  
• Players no longer get the "dirt screen" when taking something out of the Workbench

New Bugs:

• You can place objects on the Crafting Table when there is snow on it.

1.5_01
April 20, 2011
Bug Fixes:

• Blocks can now be placed on Snow / Water.
  
• Rain no longer goes through translucent blocks.
  
• Pumpkin inventory texture is now fixed. Before, it was backwards.

New Bugs:

• Many different activities will crash SMP with an "internal server error". In SMP, it is very difficult to do almost anything.
  
• On some servers if a block is placed on a snow block, the action will be immediately reversed and the snow block will return and the placed block will be added back to your inventory. (May only happen when snowing)
  
• In SSP lightning on Steps is broken. Step turns black (on newly placed steps).
  Rain now falls through Water.

1.5
April 19, 2011

• Added Weather.
  
• Added Statistics and Achievements.
  
• New Items (Detector rail, Powered Rail, Birch and Pine/Spruce Saplings).
  
• New Item Web. (Cannot be found naturally).
  
• Holding SHIFT+Click on something in a chest will immediately move the selected item(s) into your inventory and vice-versa.
  
• Birch and Pine/Spruce trees now drop Birch and Pine/Spruce saplings, respectively.
  
• Large performance improvements.
  
• Crafting a ladder now produces 2 ladders.
  
• If lightning strikes a pig, it becomes a Zombie Pigman.
  
• If lightning strikes a Creeper, it becomes electrified and will have a much more powerful explosion.
  
• New settings in options:
  
  • Ability to change GUI size (Small, Normal, Large, Auto).
    
  • Advanced OpenGL (Occlusion Culling: doesn't render blocks that the player can't "see", helps performance in cards that support it).
  
  
• Items can now be smelted with Saplings with the same smelting power as Sticks.
  
• Dropped items in flowing water move faster than before.
  
• Pigs that die by burning now drop cooked porkchops upon death.
  
• Redstone dust can be placed on snow.
  
• Wolves are more common, even in Non-Taiga/Forest biomes.
  
• Unarmed damage was increased from 0.5 <3 to 1 <3.
  
• If you resize the window (no-fullscreen) after typing in the world name and the seed, they both will be reset to "New World" and a blank seed.

Bug Fixes:

• You are only 'on' a ladder (can climb it/fall slowly) if your lower half is in the ladder block, rather than any part of you. It is no longer possible to climb a one-block gap in a ladder, or a ladder that starts at eye level.
  
• On fancy graphics, the sides of grass blocks are now biome-specific and match the shade on the top.
  
• You can now move through flowing water at previous speed.
  
• Wolves have a better understanding of doors. They will go through doors most of the time, but will sometimes get
• stuck on the 3 pixel thickness of the door. They will eventually back up for another go at the opened door.
  
• The lighting on portals and ice has been fixed (previously had triangles on the blocks) when using Smooth Lighting.
  
• On SMP, the health of wolves are now synchronized between server and client, causing wolves to only whimper when low on health, opposed to all of the time.
  
• Redstone in off state is red again.
  
• Crops hit with water now drop seeds and wheat, as opposed to just wheat.
  
• Minecarts dont stop but keep going if you log out of world

New Bugs:

• Creepers can make noises of other mobs.
  
• Sometimes it rains in snow biomes.
  
• Repetitively putting smeltable items in the furnace counts as a crafting statistic.
  
• Achievements only work in SMP if you have already completed first achievement in Single Player.
  
• Achievements will sometimes disappear when you close and re-open the game and can sometimes be restored by closing and re-oppening the game again.
  
• FPS counter shows Chunk Updates instead of FPS, usually while generating new chunks.
  
• The game will crash if Detector Rails are placed beside normal rails.
  
  • A crash will also occur if a normal rail is placed next to a Detector Rail that is connected to another rail.
  
  
• Blocks can't be placed on snow.
  
• If you change Advanced OpenGL to on and then back again, giant holes will appear that you can see through.
  
• Jumping off a fence in SMP triggers an anti-flight kick.
  
• Rain will fall through transparent blocks and stairs, acting as if there is no block there.
  
• When hitting a grass block the destroying animation is darker on the side than the animation on top of the grass block, though only on fancy graphics.
  
• Flowing water no longer pushes empty minecarts that fall into it.
  
• GUI: create new world input boxes misaligned under small and normal settings.
  
• Sometimes you might not get an achievement even if you do what it requires to get. This can usually be fixed by doing it in another world.
  
• Locked Chest is once again obtainable through inventory editing or SMP /give commands. The chests can be placed and destroyed by one hit, but no longer show the April Fools' Day menu. Locked chests will disappear after a delay.
  
• In Singleplayer, game resumes when 'Achievements' is clicked on the pause menu, instead of remaining paused.
  
• Riding in a minecart from the south into a corner going from north to west (so it's not connected to the current track) will crash the game. Possibly also true for other directions, yet if you're going in the same corner coming from the east, it will work as usual.
  
• Burning animation on furnaces may remain after done smelting.
  
  • (this bug has been here since previous versions - it certainly happens in 1.4_01... seems to happen if the chunk containing the furnace is not loaded at the instant it finishes)
  
  
• Weather ambience will stop playing while using fast graphics.
  
• Destroying a pine or birch sapling releases the particles of a 'normal' sapling.
  
• Sometimes closing and re-opening the game will reset some or all of your settings to default.
  
• More random game crashes
  
• Destroying a minecart while sitting in it will drop the player one block below ground. If the minecart was on a bridge with a single block in height, the player will fall through the bridge.
  
  • (this bug has been here since a LONG time ago... probably before powered minecarts were introduced. )
  
  
• When jumping from a fence to another fence above the fence you jumped from in SMP, you may be kicked for flying if the server uses a specific plugin.
  
• If you resize the window (no-fullscreen) after typing in the world name and the seed, they both will be reset to "New World" and a blank seed. (with all GUI-scale settings)

(don't ask me how long it took to format this, but it was a total b**tard..!!)

The server has been updated now.
