+Version 0.3.12 is now available.

+Features:
+* json-rpc errors return a more standard error object. (thanks to Gavin Andresen)
+* json-rpc command line returns exit codes.
+* json-rpc "backupwallet" command.
+* Recovers and continues if an exception is caused by a message you received.  Other nodes shouldn't be able to cause an exception, and it hasn't happened before, but if a way is found to cause an exception, this would keep it from being used to stop network nodes.
+
+If you have json-rpc code that checks the contents of the error string, you need to change it to expect error objects of the form {"code":<number>,"message":<string>}, which is the standard.  See this thread:

+Version 0.3.13 is now available.  You should upgrade to prevent potential problems with 0/unconfirmed transactions.  Note: 0.3.13 prevents problems if you haven't already spent a 0/unconfirmed transaction, but if that already happened, you need 0.3.13.2.
+
+Changes:
+* Don't count or spend payments until they have 1 confirmation.
+* Internal version number from 312 to 31300.
+* Only accept transactions sent by IP address if -allowreceivebyip is specified.
+* Dropped DB_PRIVATE Berkeley DB flag.
+* Fix problem sending the last cent with sub-cent fractional change.
+* Auto-detect whether to use 128-bit 4-way SSE2 on Linux.
+Gavin Andresen:
+* Option -rpcallowip= to accept json-rpc connections from another machine.
+* Clean shutdown on SIGTERM on Linux.

+(Thanks Laszlo for the Mac OSX build!)
+
+Note:
+The SSE2 auto-detect in the Linux 64-bit version doesn't work with AMD in 64-bit mode.  Please try this instead and let me know if it gets it right:
+http://www.bitcoin.org/download/bitcoin-0.3.13.1-specialbuild-linux64.tar.gz
+
+You can still control the SSE2 use manually with -4way and -4way=0.
+
+Version 0.3.13.2 (SVN rev 161) has improvements for the case where you already had 0/unconfirmed transactions that you might have already spent.  Here's a Windows build of it:

+Version 0.3.17 is now available.
+
+Changes:
+* new getwork, thanks m0mchil
+* added transaction fee setting in UI options menu
+* free transaction limits
+* sendtoaddress returns transaction id instead of "sent"
+* getaccountaddress <account>
+
+The 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.
+
+The accounts-based commands: move, sendfrom and getbalance <account> will be in the next release.  We still have some more changes to make first.

+There's more work to do on DoS, but I'm doing a quick build of what I have so far in case it's needed, before venturing into more complex ideas.  The build for this is version 0.3.19.
+
+- Added some DoS controls
+As Gavin and I have said clearly before, the software is not at all resistant to DoS attack.  This is one improvement, but there are still more ways to attack than I can count.  
+
+I'm leaving the -limitfreerelay part as a switch for now and it's there if you need it.
+
+- Removed "safe mode" alerts
+"safe mode" alerts was a temporary measure after the 0.3.9 overflow bug.  We can say all we want that users can just run with "-disablesafemode", but it's better just not to have it for the sake of appearances.  It was never intended as a long term feature.  Safe mode can still be triggered by seeing a longer (greater total PoW) invalid block chain.
