+udev 142
+========
+Bugfixes.
+
+Libudev allows to subscribe to udev events. To prevent unwanted messages
+to be delivered, and waking up the subscribing process, a filter can be
+installed, to drop messages inside a kernel socket filter. The filters
+match on the <subsytem>:<devtype> properties of the device.
+    This is part of the ongoing effort to replace HAL, and switch current
+users over to directly use libudev, or for higher-level services use the
+specialized D-Bus interface of a DeviceKit service.
+    Libudev is still marked as experimental, and its interface might
+change if needed, but no major changes of the currently exported interface
+are expected anymore, and a first stable release should happen soon.
+
+A too old kernel (2.6.21) or a kernel with CONFIG_SYSFS_DEPRECATED
+is not supported since while and udevd will log an error message at
+startup.
+
+DVB device naming is supplied by the kernel now. In case older kernels
+need to be supported, the old shell script should be added to a compat
+rules file.
+
+udev 141
+========
+Bugfixes.
+
+The processed udev events get send back to the netlink socket. Libudev
+provides access to these events. This is work-in-progress, to replace
+the DeviceKit daemon functionality directly with libudev. There are
+upcoming kernel changes to allow non-root users to subcribe to these
+events.

+========
+Bugfixes.
+
+"udevadm settle" now optionally accepts a range of events to wait for,
+instead of waiting for "all" events.
+
+udev 139
+========
+Bugfixes.
+
+The installed watch for block device metadata changes is now removed
+during event hadling, because some (broken) tools may be called from udev
+rules and (wrongly) open the device with write access. After the finished
+event handling the watch is restored.
+
+udev 138
+========
+Bugfixes.
+
+Device nodes can be watched for changes with inotify with OPTIONS="watch".
+If closed after being opened for writing, a "change" uevent will occur.
+/dev/disk/by-{label,uuid}/* symlinks will be automatically updated.
+
+udev 137
+========
+Bugfixes.
+
+The udevadm test command has no longer a --force option, nodes and symlinks
+are always updated with a test run now.
+
+The udevd daemon can be started with --resolve-names=never to avoid all user
+and group lookups (e.g. in cut-down systems) or --resolve-names=late to
+lookup user and groups every time events are handled.
