New Features
New confirmation pane (#1141)
All ethereum transactions only contain very few pieces of information, mostly who it comes from, who it goes to, the amount of ether and the byte code data. This last one is where all the contract magic does, yet all you could see until now was a bunch of hexadecimal numbers. In this version, we try to decode the byte code into human friendly parameters, so you can understand more what the contract is trying to do. Mist comes with almost 3000 contract signatures (thanks to @pipermerriam for creating a service that collects them ) and if you still don't have it you can still query the internet to try to decode it. With some upcoming Swarm and Solidity features we intend to make this request via Swarm, not HTTP, but right now if you click decode, you are sending a request to the site
http://4byte.directory/ which doesn't keep any logs.
Don't forget that this is just what the transaction list it does. Ultimately what the contract does is up to the code, so clicking the recipient address will take you to a page containing the contract source code that you can verify yourself.
Security fix
This Mist & Wallet 0.8.3 release contains the updated 1.4.12 Geth version. If you were experiencing issues with Mist crashing after block 2283416, then that's the likely culprit.
