appendfsync parsing in config file fixed. If you benchmarked Redis against different appendfsync options is time to try again ;)

EXPIRE behaviour changed a bit, a negative TTL or an EXPIREAT with unix time in the past will now delete the key. It seems saner to me than doing nothing.

Fixed Issue 74 (ERR just returned on invalid password), now the error message is -ERR invalid password.

A trivial change makes the new implementation O(log(N)) instead of O(log(N))+O(M) when there are M repeated scores!

backward support to skiplists for ZREVRANGE, still broken, committing since I've to merge the Solaris patches
