This release is built around two new in-house projects: aufs-ng and xfwm4-gl. aufs-ng is our new union filesystem, written from scratch to replace aufs, which PorteuX has relied on since day one. It keeps the same on-disk format and the same mount command grammar, so everything keeps working as before. It's around 5,000 lines instead of Aufs's 28,000, and it uses the kernel's modern I/O passthrough, which means much less filesystem-wide locking, considerably faster copy-up thanks to in-kernel splice instead of page-by-page buffering, and it tracks inodes only, so a warm system uses about a third of the memory. It's the default from now on. xfwm4-gl is our fork of xfwm4 that finally brings OpenGL compositing to Xfce in X11, with XRender kept as an automatic fallback. Compared to XRender it draws about a third less power and delivers roughly 10% more frames per second to applications.
