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.
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: http://www.bitcoin.org/download/bitcoin-0.3.13.2-win32-setup.exe
