1Version 0.3.17 is now available.
2
3Changes:
4* new getwork, thanks m0mchil
5* added transaction fee setting in UI options menu
6* free transaction limits
7* sendtoaddress returns transaction id instead of "sent"
8* getaccountaddress <account>
9
10The UI transaction fee setting was easy since it was still there from 0.1.5 and all I had to do was re-enable it.
11
12The accounts-based commands: move, sendfrom and getbalance <account> will be in the next release.  We still have some more changes to make first.
