I've tagged a new version - 4.11.0 - the first in a while. Apart from numerous small bugfixes, the main new features are the Dragonmint T1 driver and the coinbase decode option. As you're unlikely to use anything but the latter, I've summarised the basic instructions from the README here:
Q: How do I use the --decode function to decode a pool's coinbase?
A: You need to have a bitcoind with server functionality and pass it the
credentials as the first pool in your config, and pass the pool's address that
you wish to decode as the second pool configured. Note the bitcoind NEEDS the
http:// prefix.
e.g.:
./cgminer -o
http://localhost:8332 -u user -p pass -o solo.ckpool.org:3333 -u 15qSxP1SQcUX3o4nhkfdbgyoWEFMomJ4rZ --decode
EDIT: Updated to 4.11.1 for a missing bugfix and included NEWS outlining changelog.
