Pretty excited about this (even though its a .x release). There are some nice features in the OSS edition, including better support for OpenSSH nodes and Github OAuth, and it also is the first release where you can use the Enterprise features at a standard monthly subscription price.
Yey! 2.4 finalized another crucial feature that didn't make it into the changelog or release notes - the --insecure-no-tls flag for operating behind a proxy with SSL termination (such as with a load balancer in AWS)
Aww, still no windows bins?
Does it work with sftp/filezilla?
