+Binaries for Bitcoin version 0.3.21 are available at:
+  https://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.3.21/
+
+Changes and new features from the 0.3.20 release include:
+
+* Universal Plug and Play support.  Enable automatic opening of a port for incoming connections by running bitcoin or bitcoind with the - -upnp=1 command line switch or using the Options dialog box.
+
+* Support for full-precision bitcoin amounts.  You can now send, and bitcoin will display, bitcoin amounts smaller than 0.01.  However, sending fewer than 0.01 bitcoins still requires a 0.01 bitcoin fee (so you can send 1.0001 bitcoins without a fee, but you will be asked to pay a fee if you try to send 0.0001).
+
+* A new method of finding bitcoin nodes to connect with, via DNS A records. Use the -dnsseed option to enable.
+
+For developers, changes to bitcoin's remote-procedure-call API:
+
+* New rpc command "sendmany" to send bitcoins to more than one address in a single transaction.
+
+* Several bug fixes, including a serious intermittent bug that would sometimes cause bitcoind to stop accepting rpc requests. 
+
+* -logtimestamps option, to add a timestamp to each line in debug.log.
+
+* Immature blocks (newly generated, under 120 confirmations) are now shown in listtransactions.
