-0.9.0rc1 Release notes
+Transaction malleability-related fixes
+--------------------------------------
+
+This release contains a few fixes for transaction ID (TXID) malleability 
+issues:
+
+- -nospendzeroconfchange command-line option, to avoid spending
+  zero-confirmation change
+- IsStandard() transaction rules tightened to prevent relaying and mining of
+  mutated transactions
+- Additional information in listtransactions/gettransaction output to
+  report wallet transactions that conflict with each other because
+  they spend the same outputs.
+- Bug fixes to the getbalance/listaccounts RPC commands, which would report
+  incorrect balances for double-spent (or mutated) transactions.
+- New option: -zapwallettxes to rebuild the wallet's transaction information
+
+Transaction Fees
+----------------
+
+This release drops the default fee required to relay transactions across the
+network to 0.01mBTC per kilobyte. Note that getting a transaction relayed across
+the network does NOT guarantee that the transaction will be accepted by a miner
+and included in a block, and the default fee accepted by miners remains 0.1mBTC
+per kilobyte.
+
+As in previous releases, the relay fee may be changed with the -minrelaytxfee
+command-line option, and miners may change the default minimum fee they accept
+with the -mintxfee command-line option.
