Summary of changes from v129 to v130
============================================
udev 131
========
-Bugfixes. (And probably new bugs. :))
+Bugfixes. (And maybe new bugs. :))
The rule matching engine got converted from a rule list to a token
array which reduced the in-memory rules representation of a full
-featured distros with thousends of rules from 1.2MB to 0.17 MB.
-
-The limit of 5 ENV and ATTR matches, and a single instance for most
-other keys per rule is gone with the new parser.
+featured distros with thousends of udev rules from 1.2MB to 0.12 MB.
+Limits like 5 ENV and ATTR matches, and one single instance for most
+other keys per rule are gone.
The NAME assignment is no longer special cased. If later rules assign
a NAME value again, the former value will be overwritten. As usual
for most other keys, the NAME value can be protected by doing a final
assignment with NAME:="<value>".
-Many thanks to Alan Jenkins for finding and optimizing some of the
-computing expensive parts.
+All udev code now uses libudev, which is also exported. The library
+is still under development, marked as experimental, and its interface
+may change as long as the DeviceKit integration is not finished.

+Many thanks to Alan Jenkins for his continuous help, and finding and
