+
+Version 0.8.1 - March 22, 2011
+
+- Make --user, --pass actually work
+
+- Add User-Agent HTTP header to requests, so that server operators may
+  more easily identify the miner client.
+
+- Fix minor bug in example JSON config file
+
+Version 0.8 - March 21, 2011

+  This is a substantial speed improvement on Intel CPUs.

+  usage on upstream bitcoind / pool server.
+

+- Add --retry-pause, to set length of pause time between failure retries
+- Display proof-of-work hash and target, if -D (debug mode) enabled
+- Fix max-nonce auto-adjustment to actually work.  This means if your
+  scan takes longer than 5 seconds (--scantime), the miner will slowly
+  reduce the number of hashes you work on, before fetching a new work unit.
+
