+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
+ reporting this.
+ * build system: Handle the _POSIX_PTHREAD_SEMANTICS defined, needed by
+ Solaris, in the configure script automatically.
+ * collectd.conf(5): Various fixes and clarifications.
+ * apcups plugin: Include "collectd.h" before <stdlib.h>. This solves
+ portability problems, especially for Solaris.
+ * dns plugin: Fix a portability problem with NetBSD.
+ * 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.
+ * 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.
