PACKAGE             : syslog-ng
VERSION             : 3.1.2
SUMMARY             : new stable release
DATE                : Aug 4, 2010


  A new stable version of syslog-ng Open Source Edition (3.1.2) has been
  released. For latest fixes in the 3.1.x feature branch you are recommended to
  upgrade to this version.

        * This release changes the default for 'store-legacy-msghdr' flag
          for log sources.  In previous releases this had to be enabled
          explicitly, because of the performance penalties, which do not
          apply to 3.1. The original behaviour can be restored by explicitly
          specifying 'dont-store-legacy-msghdr'. See this blog post
          for more details:


        * When syslog-ng is reloaded, the local hostname value was not
          refreshed, causing syslog-ng to remember the hostname until the
          next restart. This may not play nice with DHCP configured
          hostnames, which may change dynamically.
        * When several SIGHUP signals are received in quick succession, the
          last one may have been dropped. This problem is fixed.
        * Make sure that numbers never get resolved using getpwnam/getgrnam
          (e.g.  libnss functions), because this may cause deadlocks if the
          NSS provider is LDAP and the LDAP server is trying to log a
          message to syslog about invalid usernames.
        * Fixed flush_timeout() handling in for non-file destinations.
          Enabling flush_lines()/flush_timeout() for a non-file destination,
          either using a global option, or a per-destination option could
          cause excess CPU usage as long as the destination wasn't writable.
        * In case patterndb has a syntax error when reloading the file,
          syslog-ng automatically reverts to the old version instead of
          dropping pattern matching altogether.
        * Fixed pdbtool to properly handle accented characters in the
          command line.
        * Fixed the use of the greedy and drop-invalid flags for csv-parser.
        * Fixed a possible but rare memory leak in the handling of message

        Other changes:
        * Added "update-patterndb" command that merges patterndb files from
          ${sysconfdir}/patterndb.d and produces ${localstatedir}/patterndb.xml,
          the default file of the db-parser().
        * Make it possible to specify the path to the syslog-ng control
          socket using a command line option in order to make it easier to
          launch multiple syslog-ng instances.
        * Introduced a new, cleaner syntax to specify that the permissions
          of a file are not to be changed. Use owner/group/perm options of a
          file without any parameters instead of "-1". The old mechanism had
          the problem that both per-file and global settings had to use "-1"
          to effectively stop syslog-ng from changing the uid/gid/perm
          values. The new syntax will make it possible to specify defaults
          the global options section and customize those on a per-file
        * syslog-ng will not go into the background if either the
          --syntax-only or --debug options are specified.

        * Added SSL support.
        * Added the ability to read from a sample file

	* We would like to send our thank for all contributors sending us
	  bugreports, documentation issues or patches.

	  They are:
	   * Marius Tomaschewski
	   * Corey Hickey
	   * Evan Rempel

	  Hopefully noone was missed from this list.
