network plugin: Added support for sending and receiving notifications.
Notifications are sent ``out of band'', i. e. each notification is one packet
and they are not mixed with performance data values.
Right now there is no configuration option to prevent listening sockets from
receiving notifications nor to prevent sending sockets from sending
notifications. This may be an option for the future, though.

This way the `<Threshold>' block doesn't need a bogus argument just to make the

collectd: Added ``associative'' members to the notification_t structure.
A notification does not need to be related to any performance data collected by
collectd, but now it *may* be related. This is used in the threshold stuff
already and passed via ExecNotification in the exec plugin, too.
The new `notification_init' function in `src/common.c' and the
`NOTIFICATION_INIT_VL' macro simplify the initialization of these new fields.

Fixed some compiler warnings identified by gcc's -Wextra option.
The following issues have been addressed:
* comparison between signed and unsigned - this was found in several places
throughout the code and has been fixed in various ways
* missing initializer - an incomplete initializer has been used for two
struct instances in perl.c
* unused parameter - when applicable, the parameter has been removed; in
thirteen cases the parameter is required by different library API's and in
two cases the parameter was left in place to retain a consistent interface
within the affected modules; as __attribute__((unused)) is a GNU extension,
it has not been used to document those exceptions

apache plugin: Improved some error messages and fixed-buffer string copying.
Return an error when initialization fails. This includes the case when no URL
is configured. The user is informed about this as clear as possible.
Also, `strncpy' and `snprintf' now are followed by a forced NULL-termination of
the strings to be on the save side. This also changes the plugin to look more
like the other plugins which mostly do this already.

collectd-exec(5): Documented the changes due to notifications and the Nagios plugin support.
Added support for more than one TypesDB file.
The "TypesDB" config option now accepts more than one filename. Each file will
be read in the specified order. If no filename has been given, the default
file will _not_ be read (I doubt this is a useful feature but it's imho the
most reasonable behavior).
This may, for example, be used to specify an additional file containing custom
data-set definitions. See the thread "Thought about exec and types.db" on the
mailing-list ([1]).

src/configfile.c: Updated the copyright notice for 2008.
libvirt plugin: Updated the copyright notice for 2008.
libvirt plugin: Fix the HostnameFormat option.
The attached patch fixes HostnameFormat in libvirt driver.
The intended use for this was:
HostnameFormat "name"
generating hostnames like "<guestname>" (the default case), and:
HostnameFormat "hostname name"
generating hostnames like "<hostname>:<guestname>".
Somewhere along the way, however, that code got broken so it always adds a ":"
before the name, and doesn't concatenate any more, so you'd get weird hostnames
appearing like ":guest" which was supposed to be "hostname:guest".
The patch just reverts back to my original code.

that no buffer overflow may occur.
