+========
+All rules are applied now, but only the first matching rule with a NAME-key
+will be applied. All later rules with NAME-key are completely ignored. This
+way system supplied symlinks or permissions gets applied to user-defined
+naming rules.
+
+Note:
+Please check your rules setup, if you may need to add OPTIONS="last_rule"
+to some rules, to keep the old behavior.
+
+The rules are read on "remove"-events too. That makes is possible to match
+with keys that are available on remove (KERNEL, SUBSYSTEM, ID, ENV, ...) to
+instruct udev to ignore an event (OPTIONS="ignore_device").
+The new ACTION-key may be used to let a rule act only at a "remove"-event.
+
+The new RUN-key supports rule-based execution of programs after device-node
+handling. This is meant as a general replacement for the dev.d/-directories
+to give fine grained control over the execution of programs.
+
+The %s{}-sysfs format char replacement values are searched at any of the
+devices in the device chain now, not only at the class-device.
+
+We support log priority levels now. The value udev_log in udev.conf is used
+to determine what is printed to syslog. This makes it possible to
+run a version with compiled-in debug messages in a production environment
+which is sometimes needed to find a bug.
+It is still possible to supress the inclusion of _any_ syslog usage with
+USE_LOG=false to create the smallest possible binaries if needed.
+The configured udev_log value can be overridden with the environment variable
+UDEV_LOG.

+Possible use of a system-wide klibc:
