+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.
+
+2009-01-02, Version 4.5.2
+ * build system: Check for `mysql.h' and `mysql/mysql.h', since the
+ file may be in both locations, especially when the database was
+ installed in a non-standard path. Thanks to Dusty Doris for
+ reporting this.
+ * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
+ Solaris, in the configure script automatically.
+ * build system, tcpconns plugin: Check for `kvm_nlist' and
+ `kvm_openfiles' before enabling the plugin: Solaris provides a KVM
+ library with similar functions to the BSD variant, but doesn't
+ provide these necessary functions.
+ * collectd.conf(5): Various fixes and clarifications.
+ * collectd: Remove a GNUism (unnamed unions), thus improving
+ portability.
+ * collectd, apcups plugin: Include "collectd.h" before <stdlib.h>.
+ This solves portability problems, especially for Solaris.
+ * dns plugin: Fix a portability problem with NetBSD.
+ * filecount plugin: Fix an off-by-one error. This error may cause a
+ segmentation fault.
+ * network plugin: Fix the handling of `type' in the network protocol.
+ Due to a programming mistake, only 4 or 8 bytes would be copied to a
+ much larger buffer. This caused the `type' to be transferred much
+ more often than necessary. In some cases, e. g. the `cpu' and
+ `cpufreq' plugins being used at the same time, data may be corrupted
+ in those files. Thanks to Bruno Prémont for debugging and reporting
+ this issue.
+ * processes plugin: Fix a possible segmentation fault when specifying
+ invalid configuration options.
+ * unixsock plugin: Make sure the initialization function is run only
+ once. This resolves a file descriptor leak under systems which run
+ the initialization more than once, such as Solaris.
+
+2008-10-16, Version 4.5.1
+ * build system: Change `--enable-<plugin>' to abort with an error if
+ dependencies are not met. Thanks to Bruno Prémont for the patch.
+ Also, the poisoning of various string functions has been restricted
+ to debug builds.
+ * collectd: Fix a memory leak in the global value cache. With every
+ *missing* value a couple of bytes would be leaked. Another memory
+ leak in the configuration handling code has been fixed. Thanks to
+ Niraj Tolia for reporting these issues.
+ * collectd: Fix an off-by-one error in the ignorelist functionality.
+ When using regular expressions, the last character would be missing,
+ possibly matching differently from what one would expect.
+ * collectdmon: Don't block SIGCHLD. This fixes a potential portability
+ problem.
+ * collectd-nagios: Fix handling of the `-d' option. Thanks to Fabian
+ Linzberger for reporting the bug.
+ * iptables plugin: Fix an off-by-one error. If a string was just one
+ character too long, it was truncated instead of reporting an error.
+ * network plugin: Fix a memory leak in the configuration handling
+ code. Thanks to Niraj Tolia for reporting this issue.
+ * perl plugin: Log an error message if bootstrapping `Collectd' fails.
+ * postgresql plugin: Don't reopen connection during reinitialization.
+ This fixes a bug under Solaris and potentially other platforms.
+ Missing calls to `PQclear' have been added, too. This fixes memory
+ leaks. Thanks to ``Admin'' for reporting these bugs.
+ * snmp plugin: Don't expect null-terminated strings from the Net-SNMP
+ library.
+ * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
+ problems with some `libc's. Thanks to Matthias Lay for reporting the
+ bug.
+
+2008-09-04, Version 4.5.0
+ * collectd: Added the ability to flush certain identifiers.
+ * collectd: The concept of `notification meta data' has been
+ introduced.
+ * filecount plugin: The new filecount plugin counts the number of
+ files in a directory and its subdirectories.
+ * ipmi plugin: Sensor names have been changed to ensure unique names.
+ Notifications upon added and removed sensors can now be generated.
+ * notify_desktop plugin: This new plugin sends notifications to the
+ X desktop using the structure defined in the `Desktop Notification
+ Specification'.
+ * notify_email plugin: This new plugin sends out notifications via
+ email, using the `esmtp' library.
+ * onewire plugin: The new experimental(!) onewire plugin reads values,
+ such as temperatures, from sensors connected to the computer via the
+ onewire bus.
+ * perl plugin: Improved synchronized access to internal data structures
+ and fixed a possible dead-lock.
+ * perl plugin: Added the ability to flush certain identifiers and marked
+ plugin_flush_all() and plugin_flush_one() as deprecated in favor of
+ plugin_flush().
+ * perl plugin: Added the ability to configure Perl plugins.
+ * postgresql plugin: The new postgresql plugin collects statistics
+ about or from a PostgreSQL database.
+ * processes plugin: The `ProcessMatch' option has been added.
+ * rrdtool plugin: Implement throttling of the `update queue' to lessen
+ IO load.
+ * tcpconns plugin: This plugin has been ported to OpenBSD.
+ * thermal plugin: The new thermal plugin collects system temperatures
+ using Linux ACPI thermal zone data.
+
+2009-01-02, Version 4.4.5
+ * build system: Check for `mysql.h' and `mysql/mysql.h', since the
+ file may be in both locations, especially when the database was
+ installed in a non-standard path. Thanks to Dusty Doris for

+ * dns plugin: Fix compilation errors with BIND versions 19991001
+ through 19991005.
+ * network plugin: Bugfix in the init routine: The init function
+ cleared a buffer regardless of its contents. This could lead to lost
+ values under Solaris.

+ to kyrone for reporting this.
+ * collectd: Fixed min/max output in notifications generated by
+ threshold checking.
+ * collectd-nagios: Fix the protocol used to communicate with the

+ René Rebe and Siegmund Gorr for reporting this.
+
+2008-05-06, Version 4.4.0
+ * collectd: Internal code cleanups.
+ * collectd: Added support for a `Flush' command in the unixsock and
+ exec plugins. This command can be used to force a plugin (or all) to
+ flush its values to disk.

+ source only, making it possible to configure different thresholds
+ for each data source.
+ * apache, nginx plugins: Added the possibility to disable host and/or
+ peer verification.
+ * ascent plugin: The new ascent plugin reads and parses the statistics
+ page of an Ascent server.

+ sensor values via IPMI, the intelligent platform management
+ interface.
+ * iptables plugin: The iptc library that is used by the iptables
+ plugin has been added to the distribution, because it is not
+ provided by all distributions and removed from at least one.
