This release includes the following features and fixes: - Fixed a bug with Multiwallets that have their own directories (i.e. cases such as DATADIR/wallets/mywallet/wallet.dat). Backups of these wallets will now take each wallet's specific directory into account. - When transactions are rejected for being low fee, the error message will read "min relay fee not met" instead of "insufficient priority". Also, a bug was fixed where sometimes low fee transactions would be accepted via sendrawtransaction (and be stuck semipermanently, as they would be unable to relay to miners). - Added nTx return value to getblock and getblockheader detailing the number of transactions in the returned block.
