+udev 136
+========
+Bugfixes.
+
+For some more advanced features Linux 2.6.22 is the oldest supported
+version now. The kernel config with enabled SYSFS_DEPRECATED
+is no longer supported. Older kernels should still work, and devices
+nodes should be reliably created, but some rules and libudev will
+not work correctly because the old kernels do not provide the expected
+information or interfaces.
+
+We are currently merging the Ubuntu rules in the udev default rules,
+and get one step closer to provide a common Linux /dev setup regarding
+device names, symlinks, and default device permissions. On udev startup,
+we now expect the following groups to be resolvable to their ids by
+glibc's getgrnam():
+  disk, cdrom, floppy, tape, audio, video, lp, tty, dialout, kmem.
+
+/dev/serial/by-{id,path}/ now contains links for ttyUSB devices,
+which do not depend on the kernel device name. As usual, unique
+devices - only a single one per product connected, or a real
+USB serial number in the device - are always found with the same
+name in the by-id/ directory.
+Completely Identical devices may overwrite their names in by-id/
+and can only be found reliably in the by-path/ directory. Devices
+specified by by-path/ must not change their connection, like the
+USB port number they are plugged in, to keep their name.
