+ 2009-05-09, Version 4.5.4
+ * Build system, various plugins: Many build fixes for FreeBSD,
+ OpenBSD, NetBSD, Solaris and Mac OS X. Big thanks to Doug MacEachern
+ for many fixes and providing a build system for many platforms,
+ Ulf Zimmermann for providing a FreeBSD system and Simon Kuhnle for
+ providing an OpenBSD system.
+ * collectd: Fix a potential race condition when creating directories.
+ * battery plugin: Don't complain about a missing directory every
+ interval.
+ * dns plugin: Slight portability fixes.
+ * exec plugin: Allow executed programs to close STDERR. Thanks to
+ Thorsten von Eicken for reporting this problem.
+ * irq plugin: Fix handling of overflowing 32-bit counters. Thanks to
+ Tomasz Pala for the patch.
+ * perl plugin: Portability build-fixes. Thanks to Doug MacEachern for
+ the patch.
+ * rrdtool plugin: Fix a possible race condition: If the network plugin
+ is initialized and dispatches a value before the rrdtool plugin is
+ initialized, the daemon may crash.
+ * memory plugin: Fix a potential problem under Solaris.
+
+2009-03-18, Version 4.6.2
+ * collectd: Some Solaris utility code has been improved.
+ * filter subsystem: Allow `Chains' without default targets.
+ * liboping: A patch to comply with strict aliasing rules has been
+ added.
+ * timediff match: Fix a typo: The match was registered with a wrong
+ name which prevented this match to be used as documented. Thanks to
+ Bruno Prémont for finding this problem.
+ * bind plugin: Fix collection of the cached RR sets. The number of RR
+ sets currently in the cache was collected as a counter value, which
+ is nonsense. Thanks to Bruno Prémont for implementing this.
+ * dns plugin: Don't pass NULL to `pcap_open_live': Some systems,
+ primarily BSDs, don't take it well and crash.
+ * oracle plugin: Portability to 64 bit systems has been improved.
+ * postgresql plugin: The default configuration has been improved.
+ * rrdtool plugin: Fix a possible race condition: If the network plugin
+ is brought and dispatches a value before the rrdtool plugin is
+ initialized, the daemon may crash.
+
+2009-02-22, Version 4.6.1
+ * collectd: Many documentation fixes.
+ * Collectd::Unixsock: Error handling has been improved.
+ * regex match: Don't link with the PCRE library.
+ * bind plugin: Various bugs have been fixed. Thanks to Bruno Prémont
+ for finding and fixing most of them.
+ * ipmi plugin: Fix an off-by-one error which could cause segmentation
+ faults. Thanks to Peter Holik for his patch.
+
+2009-02-16, Version 4.6.0
+ * collectd: Added the `filter chain' infrastructure, which allows the
+ user to use `matches' and `targets' to control value processing.
+ * collectd: The new `-T' command line argument allows more in-depth
+ testing of a configuration. Thanks to Doug MacEachern for the patch.
+ * collectd-nagios: The Nagios integration command has been updated to
+ use libcollectdclient. The `percentage' aggregation function has
+ been added. Thanks to Fabian Linzberger for the patch.
+ * libcollectdclient: A library which abstracts communication with the
+ unixsock plugin for clients has been added.
+ * regex match: Match values by their identifies using regular
+ expressions.
+ * timediff match: Match for values with an invalid timestamp.
+ * value match: Select values by their data sources' values.
+ * notification target: Create and dispatch a notification.
+ * replace target: Replace parts of an identifier using regular
+ expressions.
+ * set target: Set (overwrite) entire parts of an identifier.
+ * bind plugin: This new plugin uses the new HTTP/XML interface to BIND
+ statistics, allowing very detailed name server statistics. Thanks to
+ Bruno Prémont for this plugin.
+ * cpu plugin: Report `interrupt' separately when using
+ sysctlbyname(3) (used under *BSD). Support for sysctl(3), for
+ example for native OpenBSD support, has been added. Thanks to Simon
+ Kuhnle for the patch.
+ * csv plugin: Make it possible to write values to STDOUT instead of
+ files. This is meant for testing purposes mostly. The output written
+ to STDOUT is compatible with the exec plugin. Thanks to Doug
+ MacEachern for the patch.
+ * curl plugin: This new plugin can be used to read web pages and parse
+ them using the same mechanism that's used in the tail plugin.
+ * dbi plugin: This new plugin allows you to connect to a variety of
+ relational databases and use SQL to gather custom statistics from
+ it. It is similar to the already existing PostgreSQL plugin but uses
+ libdbi to communicate with the database(s).
+ * interface plugin: Use the ignorelist framework when selecting /
+ ignoring interfaces. This allows one to use regular expressions to
+ select interfaces, too.
+ * ipmi plugin: Handle temporary IPMI error conditions more gracefully.
+ Thanks to Bruno Prémont for this patch.
+ * memcached plugin: Add hit-ratio metric. Thanks to Doug MacEachern
+ for the patch.
+ * mysql plugin: Allow connecting to a database via the UNIX domain
+ socket, too. Thanks to Mirko Buffoni for the patch.
+ * network plugin: Further performance improvements for the receive
+ code. This hopefully will help very large setups.
+ * openvpn plugin: This new plugin collects statistics provided by the
+ OpenVPN daemon. Thanks to Doug MacEachern for the patch.
+ * oracle plugin: This new plugin allows you to connect to an Oracle
+ database and use SQL to gather custom statistics from it. It is
+ similar to the already existing PostgreSQL plugin.
+ * perl plugin: Compatibility fixes for broken versions of Perl 5.10
+ have been added.
+ * perl plugin: Export the newly added plugin_write() to Perl plugins.
+ * perl plugin: Added support for `notification meta data'.
+ * perl plugin: Added support for the `filter chain' infrastructure by
+ allowing plugins to register `matches' and `targets'.
+ * postgresql plugin: The preferred configuration syntax has been
+ updated to be in line with the syntax used by the new dbi and oracle
+ plugins. The compatibility code for the old syntax is present.
+ Support for the new `Result' blocks and the interval parameter has
+ been added.
+ * processes plugin: Stacksize and virtual memory usage statistics have
+ been added. Portability fixes.
+ * rrdcached plugin: This new plugin uses the (still in development)
+ RRD accelerator daemon, rrdcached. This daemon works very similar to
+ the original rrdtool plugin of collectd, but adds some more nice
+ features.
+ * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
+ added.
+
2009-02-22, Version 4.5.3
* build system: The check for libupsclient even when `pkg-config' is
not available.
