2.1.2
	Wed, 12 Nov 2008 12:25:37 +0100

	Bugfixes:
	* Fixed handling windows sizes above 65535 by changing the internal
          reference counter type to a 32 bit integer.
	* Fixed the reported port number in log statistics messages.
	* Fixed the internal representation of "facility" values, earlier an
	  8 bit value was used for both the priority and facility values,
	  and although systems do not define facilities in this range, 
	  the LOG_FACMASK macro defines two additional bits. The type of
	  this field was changed to 16 bits.
	* Fixed filter evaluation, the evaluation in AND and OR operators
	  had a problem, it evaluated the right-hand-size of expressions
	  first, and then the left-hand-side. This is wrong, and it easily
	  ruins the concept of extracting information from messages via
	  regexps.
	* Fixed a segmentation fault in the configuration parser on
	  OpenBSD/amd64. All configuration options that expected a number in
	  the parser may cause a crash, as the strdup() function went
	  undeclared on OpenBSD, causing it to be auto-declared as a
	  function returning "int". As a 32 bit int cannot hold a 64 bit
	  pointer, this may cause a crash if the high-order bits of the
	  pointer are lost.
	* Fixed a possible "stall" of the syslog-ng main loop, when SQL
	  destinations are used and flow control is enabled on the log path
	  feeding the SQL destination.
	* Fixed a possible 100% CPU usage case on HP-UX. HP-UX may return
	  POLLERR on its own without the other flags set, this was not
	  properly handled by syslog-ng, causing it to spin on the CPU.

	Other changes:
	* Instead of relying on BalaBit's version of libdbi, adapt the
          configure script to libdbi upstream. This currently means that
	  instead of dbi-0.8.pc, syslog-ng is looking for dbi.pc, just as
          the upstream installs the pkg-config file.
        * Added --enable-mixed-linking option to the configure script. This
          functionally equivalent of the default linking option in
          syslog-ng 2.0. This change only makes this possibility more
          explicit.
        * Fixed some compilation warnings.
        * Removed the build dependency on flex 2.5.34.


2.1.1
	Thu, 28 Aug 2008 09:26:30 +0200

	Bugfixes:
	* Fixed a possible crash in stats message generation.
	* Fixed compilation problem in loggen on FreeBSD.

	Other changes:
	* The netmask filter was changed to assume that local messages are
          received from 127.0.0.1.

2.1beta2
	Fri, 13 Jun 2008 14:37:08 +0200

	Bugfixes:
	* Create /var/lib/syslog-ng directory from RPM packages.
	* Fixed a 100% CPU usage problem triggered by the pipe()
          destination. This is a regression in 2.1beta1 and does not affect
          earlier versions.
	* Removed test code that injected "Connection timed out" errors into
	  local file writes.
	* Set the current directory to the root once syslog-ng daemonized
          itself.
	* Fixed the $PID macro to only extract information from the syslog
          message header and not from the message contents.

	Other changes:
	* Instead of using O_APPEND for file writes, add an lseek before
          writing which performs much better with the NFS client in BSD
	  kernels.
	* Added support for suppressing duplicate messages. This feature was
	  contributed by Chris Packham.
	* The default linking mode is changed to dynamic linking, as static
          linking is more difficult for users to cope with. Those who
	  use NFS mounted /usr on machines where syslog-ng runs on will
          probably need to explicitly ask for the previous behaviour.

2.1beta1
	Fri, 18 Apr 2008 18:00:59 +0200

	Bugfixes:
        * Fixed a possible SIGABRT crash if the hosts file passed to
          dns-cache-hosts() had multiple entries with the same IP address.
        * Fixed a bug that caused the persistent DNS cache (e.g. /etc/hosts)
          to be reloaded for all name resolution requests.
        * Fixed a possible crash during startup if "-g" was specified without
          using "-u".
        * Fixed handling more than 256 destinations by changing the
          reference counter type of LogMessages to a 16 bit value.
	* Fixed door initialization on Solaris, the door portion of
          sun-streams() sources did not work in previous releases.
	* Fixed a possible segmentation fault in handling file
          sources that are marked optional and the source file does not
	  exist.
	* Fixed the LinkSys style timestamp parser to avoid recognizing
          hostnames starting with numbers as the year value of the
	  timestamp.
	* Fixed the year recognition heuristics as the older used the
	  previous year in some cases when the client's clock was too fast.

	Other changes:
	* Backported end-of-message search algorithm from PE, which results
          in increased performance and the removal of vague interpretation
	  of messages that contain both NUL and NL characters.
	* Removed destination files from the set of polled fds, they are
	  always writable anyway and cause performance degradation when a
	  lot of destination files are managed.
	* Fixed some FreeBSD and AIX portability issues.
	* Added the BSDTAG macro, implementation by Jung Christian.
	* Changed the reconnection logic in the TCP destination driver to
	  reattempt connections for any kind of network problems. Therefore
	  an unknown DNS name will not prevent syslog-ng to start up with an
	  initialization error.
	* Changed the file write error handling logic to suspend writing to
	  a file destination on write errors, but retry it some time later.
	  This time interval is controlled by time_reopen() just like with
	  other drivers.


2.1alpha1
	Sun, 13 Jan 2008 10:07:57 +0100

	This is the first release of syslog-ng Open Source Edition 2.1.x
	It contains the following changes over syslog-ng OSE 2.0:

	New features:
	* SQL destination driver
	* The outgoing message rate is controllable via the "throttle"
	  option.
