+2009-09-13, Version 4.8.0
+
+ * collectd: Two new data source types, “DERIVE” and “ABSOLUTE”, have
+ been added. “DERIVE” can be used for counters that are reset
+ occasionally. Thanks to Mariusz Gronczewski for implementing this.
+ * thresholds: The advanced threshold options “Percentage”, “Hits”, and
+ “Hysteresis” have been added. Thanks to Andrés J. Díaz for hit
+ patches.
+ * curl_json plugin: The new cURL-JSON plugin reads JSON files using
+ the cURL library and parses the contents according to user
+ specification. Among other things, this allows to read statistics
+ from a CouchDB instance. Thanks to Doug MacEachern for the patch.
+ * df plugin: Using the new “ReportByDevice” option the device rather
+ than the mount point can be used to identify partitions. Thanks to
+ Paul Sadauskas for the patch.
+ * dns plugin: The possibility to ignore numeric QTypes has been added.
+ Thanks to Mirko Buffoni for the patch.
+ * GenericJMX plugin: The new, Java-based GenericJMX plugin allows to
+ query arbitrary data from a Java process using the “Java Management
+ Extensions” (JMX).
+ * madwifi plugin: The new MadWifi plugin collects information about
+ Atheros wireless LAN chipsets from the MadWifi driver. Thanks to
+ Ondrej Zajicek for his patches.
+ * network plugin: The receive- and send-buffer-sizes have been made
+ configurable, allowing for bigger and smaller packets. Thanks to
+ Aman Gupta for the patch.
+ * olsrd plugin: The new OLSRd plugin queries routing information from
+ the “Optimized Link State Routing” daemon.
+ * rrdtool plugin: A new configuration option allows to define a random
+ write delay when writing RRD files. This spreads the load created by
+ writing RRD files more evenly. Thanks to Mariusz Gronczewski for the
+ patch.
+ * swap plugin: The possibility to collect swapped in/out pages has
+ been added to the Swap plugin. Thanks to Stefan Völkel for the
+ patch.
+ * tokyotyrant plugin: The new TokyoTyrant plugin reads the number of
+ records and file size from a running Tokyo Tyrant server. Thanks to
+ Paul Sadauskas for the patch.
+ * write_http plugin: The new Write HTTP plugin sends the values
+ collected by collectd to a web-server using HTTP POST requests.
+ Thanks to Paul Sadauskas for the patch.
+ * zfs_arc plugin: The new ZFS ARC plugin collects information about
+ the “Adaptive Replacement Cache” (ARC) of the “Zeta File-System”
+ (ZFS). Thanks to Anthony Dewhurst for the patch.
+ * empty_counter match: The new Empty Counter match matches value
+ lists, where at least one data source is of type COUNTER and the
+ counter value of all counter data sources is zero.
+
+ 2009-09-13, Version 4.7.3
+ * 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
+ value was assigned to a wrong variable. The initialization of the
+ gcrypt library, which is used for signing / encrypting traffic, has
+ been fixed. Thanks to Luke Heberling for the patch.
+ * powerdns plugin: Set a timeout when reading data from the datagram
+ socket. Handling of the “LocalSocket” option has been fixed. An
+ incorrectly used “type” has been corrected. Thanks to Luke Heberling
+ for his patches.
+
2009-07-19, Version 4.7.2
* Build system: Support for `DESTDIR' has been fixed in the Java
bindings.
