Mojang said on their website:

One day this piece of text will contain some really important information that could change the fate of Humanity, and nobody would know because nobody reads this text anyway. Oh, sorry, what was that? Snapshot? Oh right yes of course! Here we go:

Notable additions for survival:

• Book copying mechanics has been altered to differentiate the original & copies of books
• Activator rails can eject entities from Minecarts

Notable additions for mapmakers:

• Added a spectator gamemode (/gamemode spectator). Not 100% finished.
• Spectators cannot be seen by anybody but other spectators
• Spectators can view inventories/etc, but not modify them
• Spectators can go through any entity or block without interfering with it
• Spectators can click on entities to take their camera
• Spectators cannot use items, place blocks, destroy blocks or interact with blocks in any way
• Spectators are only slightly buggy maybe sometimes

Please report any and all bugs you find in Minecraft to bugs.mojang.com. If nobody reports a bug, we can’t fix it!
