+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.
* 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 but.
+ 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
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' after reading an EOF. This fixes
+ * tail plugin: Call `clearerr(3)' after reading an EOF. This fixes
problems with some `libc's. Thanks to Matthias Lay for reporting the
bug.
* thermal plugin: The new thermal plugin collects system temperatures
using Linux ACPI thermal zone data.
