There is a new version of the Windows LiveJournal client available at http://www.livejournal.com/download/.
The main cool feature of this version is the ability to select which picture you want associated with your post based on keyword. The other major thing that changed is that the client now sends a hashed password instead of the plaintext password. This protects you from someone being able to grab your plaintext password (in case you use it elsewhere).
There were also some minor cosmetic changes... ctrl-s is now listed in the menu and the about box was updated to give credit for the md5 routines (for the password hashing).
I hope you like it.
