Added the new block types:
And fixed a bug that stopped you from opening your save while Minecraft is currently running.

Sorry about the delay, I had (lots) of course work for college, and DrSchnz is working on other things, I was planning on doing it in some free time I had, but I kept procrastinating though, that’s when I received a message from AndruinGreydawn, he fixed the loading code so all I needed to do was fix the main menu (Thanks!), which turned out okay
Not much to say, it’s fixed to support your 1.3 maps, if you wan’t to open the older < 1.2 maps then you will need the older version of MineViewer, and added the Lua constant for the new repeater block, oh and the menu changed a little too, not a grave deal you should see though, just behind the scenes.
Here is a complimatry image of the new menu:

MineViewer has been updated to support new blocks in Minecraft beta, sorry about the delay, I was working on getting MineViewer to connect to SMP servers (Don’t worry server admins, read further down), which I wanted to come with this update, unfortunately it is not complete and is buggy, so use it with caution, transparency is another new feature which has been implented.
For server admins who are concerned and do not want MineViewer to connect to their server, add “-nc” to the very start of your motd and MineViewer will refuse to connect.
Picture time 
(Ill get more screen shots when minecraft.net comes back up)
Oh, just make sure you click the little “^” button on the chat form and select force map download, this will move the player around slightly so the server sends us those precious chunks (just make sure you unload the chunks and reload them).

EDIT: Updated MineViewer to connect with the new launcher.
EDIT 2: Is he doing this on purpose? Fixed auth again.
As some of you may or may not know, Ddrl46 joined the team to take MineViewers current GUI and upgrade it and I must say he done a fantastic job, there are some other newer features too, one of those new features is bookmarks, just hit ‘B’ and you can create, jump and remove your bookmarks, the bookmarks are also compatible with SMPs warps.txt.
Oh, here is a nice video to go with the update 
Another thing many of you will be grateful for is a block key, which was also added:

Thats all, thank you and have a nice christmas
It’s over-engineered, and messy in many places. Here you go:
MineViewer Project on GitHub
MineViewer now supports The Nether and all updated block types!
If you view your world from another dimension than you currently are in the save then the position is automatically translated to where you would come out so you can accurately make your teleports in the position you want them!
