+
+2009-12-18, Version 4.7.5
+ * Build system, java plugin: Don't use “find -L” to search for Java

+ * collectd: Fix a possible but very rare invalid “free” in the caching
+ code. Thanks to Sebastian Harl for the patch.
+ * collectd: Remove old values when a cache entry is marked as missing.
+ This way the “GETVAL” command of the UnixSock plugin doesn't return
+ old, no longer valid values when this happens. Thanks to Andrés J.
+ Díaz for the patch.
+ * collectd: The “plugin_unregister_read” function has been fixed.
+ * apache, ascent, bind, curl, nginx plugins: Advise the cURL library
+ to follow redirects. Thanks to Joey Hess for reporting this bug.
+ * df plugin: Check the ignorelist before stating the file system,
+ possibly reducing the number of stats considerably. Thanks to Joey
+ Hess for reporting this bug.
+ * iptables plugin: Support for the new libiptc API has been added.
+ Thanks to Sebastian Harl for the patch. The build system has been
+ updated to the plugin only includes the shipped header files when it
+ is linked with the shipped library, too.
+ * java plugin: Delay creating the JVM until after the daemon has
+ forked. The JVM internally creates threads that are lost when
+ forking. This means that Java-based plugins are now configured
+ during the init-phase, i. e. later than other plugins.
+ * libvirt plugin: Re-connect to libvirtd if connecting fails. Thanks
+ to Alan Pevec for the patch.
+ * network plugin: Fix the handling of the “CacheFlush” option: The

+ uptime. Thanks to Marco Chiappero for the patch.
+
+2009-09-10, Version 4.6.5
+ * collectd: Remove old values when a cache entry is marked as missing.

+ * 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.

+ 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.

+ 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.

+ 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.

+ 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'.

+ 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)

+ features.
+ * swap plugin: Code for OpenBSD (and possibly other *BSDs) has been
+ added.
+
+2009-05-09, Version 4.5.4
+ * Build system, various plugins: Many build fixes for FreeBSD,

+
+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

+ 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

+
+2008-05-06, Version 4.4.0
