* apache / network plugins: Improved initialization order hopefully
resolved gcrypt initialization problems.
* aquaero plugin: The type used to submit fan utilization was fixed.

* collectd: The "AutoLoadPlugin" option allows to automatically load
plugins for which a configuration is found.
* collectd: The "WriteQueueLimitHigh" and "WriteQueueLimitLow" options
allow collectd to drop values when under stress, to avoid running out
of memory. Thanks to Yves Mettier for his patch.

"GraphiteAlwaysAppendDS" options have been added. Thanks to Laurent
for the patch.

patch.

Logical Volume Manager (LVM). Thanks to Chad Malfait for his work.
* memcached plugin: Support for increment and decrement counts has been
added. Thanks to Blake Matheny for the patch.
