Xfce 4.12 is running about two years behind its original schedule but there's now a concerted effort underway to get out this lightweight GTK+ desktop environment out around the end of February or early March.
Simon Steinbeiß wrote on the xfce4-dev list, "we're writing to you [core Xfce component maintainers] proposing a concrete release date for 4.12 about a month from now, the weekend of February 28 and March 1. As we have discussed the status and progress of core components with many of you individually, we feel confident that the state of Xfce is good enough to polish some final edges and push more translations until then."
It seems most developers are fine with the plans to release in just shy of one month, though there is the list of open critical bugs.
While this release is coming two years late, this still isn't the update that transitions entirely over to GTK+ 3. Xfce 4.12 still defaults to GTK+ 2 with partial GTK+ 3 support.
Stay tuned for more Xfce 4.12 coverage in the weeks ahead.
