API Version 2:
The V2 API URL is:
Documentation
unofficial documentation (So far the best we have) is provided at :
https://bitbucket.org/nitrous/mtgox-api/overview
(The bitcointalk forum link is: https://bitcointalk.org/index.php?topic=164404.0
official docs are on :

Technical Use Explanation:
The requested path (anything after the /2/) must now be included when you compute your hashed signature (Rest-Sign) for added security.
This is how it was done for version 1:
You have your params(post_data) = the word nonce, followed by the actual nonce integer (params = [(u'nonce',nonce)])
You have your header made up of Rest-Key (your API-KEY) and Rest-Sign (a hashed signature)
Rest-Sign is created by doing : base64encode( HMAC hash( base64decoded(API-secret), the nonce, with SHA512 digest))
What differs in version 2 is now : BEFORE the nonce, you are adding the relative path you are requesting(ie: BTCUSD/money/ticker) + a NUL char (ascii code 0).
The URL is now something along the lines of BTCUSD/money/order/add instead of BTCUSD/private/order/add in api1.
So in my python code below which is very readable you can see everything remains the same as API v1 except now we are using api2postdatatohash = path + chr(0) + post_data #new way to hash for API 2, includes path + NUL.
Explanation of Methods
BTCUSD/money/order/quote
<@MagicalTux> it estimate the result of running an order at a given price based on market depth
BTCUSD/money/ticker_fast
Solves the problem of ticker lag. (supposedly)
Code Examples:
C# :
https://bitbucket.org/pipe2grep/cryptocoinxchange C# lib for V2 API and socketIO
Python v 2.7.3
http://pastebin.com/aXQfULyq - Remove any proprietary unlock_api_key stuff. You'll need json_ascii also. Works on API 0/1/2. Link to git-repo: genbtc's trader.python
Perl
