Adrien posted the latest of his monthly update reports, this one for July, and there are some big ones in there. For starters, USB3 support is now enabled by default, so if you've had problems in the past, try a recent nightly and see if it changed. If you're still having issues, don't forget to log a ticket with Tracker, if you haven't already. The Media Kit keeps being worked on by Barrett, with the latest changes improving URL handling in different scenarios.
As you can see from the link above, Adrien's post contains several other items, from cddb_lookup to GCC6 and Tracker, so head over and read the whole thing. As always, great stuff from the devs involved with our little OS, nicely done!
