PACKAGE             : syslog-ng Premium Edition
VERSION             : 4 F2 (4.2.1)
SUMMARY             : New syslog-ng Premium Edition feature release
DATE                : Feb 20, 2012
------------------------------------------------------------------------------

  Dear syslog-ng Premium Edition Users,

  A new feature version of the syslog-ng Premium Edition (PE) has been
  released.

  The main new features of syslog-ng Premium Edition 4 F2 (4.2.1) are
  briefly summarized below:

WARNING
    New license required for multi-CPU operation
    Note that version 4 F2 of syslog-ng Premium Edition includes
    multi-threaded processing with a 2 CPU core limit. If you are upgrading your
    syslog-ng PE server from version 4.1 to 4.2 and your syslog-ng PE deployment
    requires more than 2 CPU cores, you will need to obtain a new license file,
    free of charge, from the BalaBit sales department.

  Reliable disk-based buffering

  * Reliable disk-based buffering is now available in syslog-ng PE. Use reliable
    disk-based buffering if you do not want to lose logs in case of
    reload/restart, unreachable destination or syslog-ng PE crash. This solution
    provides a slower, but reliable disk-buffer option. The disk-buffer file is
    created and initialized at startup and gradually grows as new messages
    arrive.

  Collecting messages from tables or relational database

  * Starting with version 4 F2, the syslog-ng PE application is able to collect
    messages from tables or relational database, using the sql() driver.
    Currently the Microsoft SQL (MSSQL), MySQL, Oracle and PostgreSQL databases
    are supported. The syslog-ng PE application can connect to a database,
    collect records from a table and then create a message from each record.
    Every query executed by the SQL source can be customized.

  Reliable Log Transfer Protocol

  * The syslog-ng application can send and receive log messages in a reliable
    way over the TCP transport layer using the Reliable Log Transfer Protocol
    (RLTP). RLTP is a new transport protocol that prevents message loss during
    connection breaks. It detects the last received message on the receiving end
    and then starts resending messages from that point. Therefore, messages are
    not duplicated at the receiving end in case of a connection break. It also
    allows the negotiation of using TLS with a single source driver.

  New hard macro: Unique receipt ID

  * A unique ID for messages generated at reception time on the receiving host.
    It facilitates defining relationships between messages that are potentially
    distributed to different files on the same host, or different hosts.

  Installation path in .RUN installer

  * The syslog-ng PE application can be installed to an alternative location.
    It can be useful if the user intends to install syslog-ng PE without
    registering it as a service, or if it cannot be installed to the default
    location because of policy compliance reasons.

  Other changes

  * Starting with version 4 F2, lgstool cat and lgstool tail --filter option
    is available.
  * From 4 F2, syslog-ng PE will limit the number of processors/cores used by
    syslog-ng PE. It is limited in the license file, through the Max-Processors
    entry. If you are upgrading your syslog-ng server from version 4.1 to 4.2
    and your syslog-ng deployment requires more than 2 CPU cores, you will need
    to obtain a new license file, free of charge, from the BalaBit sales
    department. Please contact the sales department at sales at balabit.com
  * AIX 7.1 has been added to the list of supported platforms

    #25724: The -Q command line option of the syslog-ng binary is functional
            again
    #24544: Fixed rewrite rule evaluation in case they were referenced from
            multiple locations
