Most of the new features will find their way into -stable in the coming weeks. One curiosity though is the lack of DTrace providers in some notable ports. I don't really use httpd a lot lately but I think this would be a rather obvious strength for FreeBSD so I added the idea and a link to sources to the WantedPorts Wiki. A complete description is here: http://dtrace.org/blogs/dap/2011/12/13/usdt-providers-redux/ (note the link to the mod_usdt provider [1]. ) plus we have our own notes about providers in FreeBSD that could use some enhancements: https://wiki.freebsd.org/DTrace/userland Regards, Pedro.
