+udev 057
+========
+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.

+udev 056
+========
+Possible use of a system-wide klibc:
+ make USE_KLIB=true KLCC=/usr/bin/klcc all
+will link against an external klibc and our own version will be ignored.

udev 055
========
We support an unlimited count of symlinks now.
If USE_STATIC=true is passed to a glibc build, we link statically and use
a built-in userdb parser to resolve user and group names.
-THE PLACE= key is gone. It can be replaced by an ID= for a long time, cause
+The PLACE= key is gone. It can be replaced by an ID= for a long time, cause
we walk up the chain of physical devices to find a match.
+The KEY="<value>" format supports '=', '==', '!=,' , '+=' now. This makes it
+easy to skip certain attribute matches without composing rules with weird
+character class negations like:
+ KERNEL="[!s][!c][!d]*"
+this can now be replaced with:
+ KERNEL!="scd*"
+The current simple '=' is still supported, and should work as it does today,
+but existing rules should be converted if possible, to be better readable.
+
+We have new ENV{}== key now, to match against a maximum of 5 environment
+variables.
+
+udevstart is its own binary again, cause we don't need co carry this araound
+with every forked event.
