Memcached 1.4.0 released. The big new feature is the (optional) binary protocol, which enables other features such as CAS-everywhere and efficient client-side replication. Maintainer Dustin Sallings has also released some useful sounding EC2 instances which automatically assign nearly all of their RAM to memcached on launch and shouldn’t need any further configuration.

Thanks for the link and for pointing out that the binary protocol is indeed optional (the older protocol is still first-class).
Just a quick note: I do a lot of work on the server and am part of the core team, but dormando is still our king. :)
