The first thing to notice is the shiny new splash screen highlighting the new owner of the project that being Rapid7.
A notice that I don't have the latest update appears, so auto update is performed after confirmation.
Following some local testing of random wordpress plugins in a turnkey linux virtualbox host I found the w3af framework to be much improved in terms of stability and speed. This is a welcome improvement as previously python traces and broken scans was annoying enough to make it unusable unless stepping through and performing one or two audit plugins at a time.
Further exploration is required, as the potential for an excellent open source web application testing framework has always been there. I expect to see closer integration between Metasploit and w3af in future releases.
