* 2010-03-16, prelude-manager-1.0.0:
- Minor changes since rc1.
* 2010-01-29, prelude-manager-1.0.0rc1:
- Upgrade to libev 3.9
- Use pkg-config for GnuTLS detection, as required by recent GnuTLS
version.
- Various bug fixes.
* 2009-07-10, prelude-manager-0.9.15:
- Make Prelude-Manager thread backend independant.
- Add missing dlpreopening support for the SMTP plugin.
- Win32 compilation fixes.
- Various fixes and update.
* 2008-08-21, prelude-manager-0.9.14.2:
- Various build fixes (#306).
* 2008-07-29, prelude-manager-0.9.14.1:
- Correctly define HAVE_LIBPRELUDEDB, so that more SMTP plugin
features are enabled.
* 2008-07-18, prelude-manager-0.9.14:
- Improve thread safety when evicting events to disk.
- Handle IDMEF message version tag, which will be used in upcoming
libprelude version.
- Add support for newer GnuTLS 2.2.0 session priority functions. When
the option is available, the user might specify TLS settings through
the "tls-options" configuration entry.
- Fix a possible crash upon destruction of a bufpool that is writing to
a failover.
- Correct strtoul() error checking, when verifying scheduler options.
* 2008-04-28, prelude-manager-0.9.13:
- Update libev, and GnuLib code.
- The commercial Prelude-Manager-SMTP plugin is now open-sourced, and
included within the Prelude-Manager tarball!
* 2008-04-28, prelude-manager-0.9.12.1:
- Update libev, and GnuLib code.
* 2008-04-01, prelude-manager-0.9.12:
- Use libev in place of the server-logic architecture: libev provides
the most scalable event notification mechanism available on a given
operating system.
- New connection-timeout option, governing the maximum number of
seconds a client might take to authenticate (default: 10 seconds).
- Fix a possible file descriptor leak on connection closure error.
- Massive cleanup of the build process, enable RELRO when possible.
- Fix a number of potential race in the reverse relaying code.
- When reverse relaying messages, encode the same message once for all
recipients: this improve performance with more than one reverse
relaying client (was a long time FIXME).
- Libev introduction also fix a rare issue where server-logic would not
notice a dead connection.
* 2008-02-07, prelude-manager-0.9.11.2:
- Missing config.h inclusion, leading to GnuLib module compilation failure
on some architecture (Solaris). Fix #278.
* 2008-02-06, prelude-manager-0.9.11.1:
- Add missing strsep module from GnuLib, fix build failure on architecture
missing strsep (Solaris). Fix #277.
* 2008-02-05, prelude-manager-0.9.11:
- In case a lot of message were being processed, the heartbeat timer
could be delayed for a long period of time.
- The old scheduler algorithm could be unfair when certain message priority
were not available for processing. We now appropriatly handle repartition
to others priority messages.
- Message of the same priority could be processed in the wrong order when
on-disk buffers were used.
- No integrity check were performed on orphan on-disk buffer in case of an
operating system crash. By using the prelude-failover API, we can now
detect possibly corrupted disk buffer, or resume at the time we stopped
recovering them.
- New sched-priority and sched-buffer-size configuration options.
- Fix a bug where several relaying plugin instance would only forward
their message to a single Manager.
* 2007-10-02, prelude-manager-0.9.10:
- Make threshold act like a real threshold: pass every Nth events
in the defined amount of seconds.
- Allow mixing Limit and Threshold.
- Do not share the tresholding hash accross thresholding plugin instance:
previously, the shared hash would result in strange thresholding plugin
behavior if you had several instance of thresholding loaded.
- Various bug fixes concerning plugin instance un-subscribtion (unsubscribtion
of certain plugin was not triggered).
* 2007-09-23, prelude-manager-0.9.9.1:
- Fix for new libprelude (0.9.15) runtime warning.
- Add documentation for SQLite3 in the template configuration file
(Sébastien Tricaud <toady at gscore.org>).
* 2007-08-03, prelude-manager-0.9.9:
- Update configuration template, add documentation for Prelude
generic TCP options.
- Implement modified patch from Pierre Chifflier <[email protected]>
to fix the example log path (fix #224).
- Move IDMEF message normalization in the scheduler, rather than
doing it upon reception. This remove some load from the server
and allow Prelude-Manager own IDMEF messages to go through the
normalizer path.
- Implement heartbeat->analyzer normalization.
- Improve IPv4 / IPv6 address normalization.
IPv4 mapped IPv6 addresses are now mapped back to IPv4.
Additionally, the Normalize plugin now provide two additionals option:
ipv6-only: Map any incoming IPv4 address to IPv6.
keep-ipv4-mapped-ipv6: do not map IPv4 mapped IPv6 addresses back to IPv4.
- Make a difference between exceptional report plugin failure (example:
a single message couldn't be processed) and "global" plugin failure
(example: database server is down). We use a different failover for
'exceptional' failure, so that we don't try to reinsert a bogus message
(fix #247).
- Start of a Prelude-Manager manpages (#236).
- Various bug fixes.
* 2007-05-02, prelude-manager-0.9.8:
- Initial implementation of the 'thresholding' plugin, allowing you to
suppress events after a certain limit/threshold.
- Filters hooking to a reporting plugin are now OR'ed instead of being
AND'ed. AND is already possible by hooking filtering plugin one with
another.
- Improved error reporting.
- Minor bug fixes.
* 2007-03-16, prelude-manager-0.9.7.2:
- Allow filtering plugins to hook others filters plugins.
- Update reporting code to latest specification for the SNMPService class.
- Warn about Un-handled command line arguments.
- Properly dump IDMEF-XML output (fix #186).
- Various bug fixes.
* 2006-12-21, prelude-manager-0.9.7.1:
- Fix compilation issue on system where ferror is not declared as a function,
regression introduced in 0.9.7 (#186).
* 2006-12-20, prelude-manager-0.9.7:
- Fix a startup problem on system with different address of different family
mapping to the same IP.
- Fix for system using the GnuLib poll replacement modules. The module was
broken when used in conjunction with server socket.
- Various portability fixes (this release should compile and run on OSX out of the box).
* 2006-10-04, prelude-manager-0.9.6.1:
- Fix possible undefined reference to GnuLib symbols.
- Verbose error message in case of Authentication initialization failure.
* 2006-08-24, prelude-manager-0.9.6:
- In case an IDMEF-Service object contain neither name or port
attribute, set name to "unknown" in order to avoid IDMEF DTD
validation issue.
- Normalize analyzer(*).node.
- Fix OpenBSD getaddrinfo() problem.
* 2006-06-14, prelude-manager-0.9.5:

- XMLmod: Process the Checksum IDMEF element.
- XMLmod: Make AdditionalData validation pass (IDMEF v15 -> v16 change).
- XMLmod: disable-buffering option argument is optional.
- XMLmod: Correct DTD loading error.
- XMLmod: Avoid NULL libxml warning.
* 2006-03-28, prelude-manager-0.9.4.1:
- Enable write notification on queued write (Fix reverse relaying).
- Fix IDMEF message scheduler warning when plugin failover is enabled.
* 2006-03-17, prelude-manager-0.9.4:
- Fix reverse relaying on some architecture due to thread safety
issue.
- Server scalability improvement in case of message burst.
- Start work on a normalization plugin. Very simple for now, mostly
sanitize IDMEF Address and IDMEF Service classes.
- When an analyzer have read and write permission to prelude-manager,
avoid acting as an echo server, don't send received message from this
analyzer to itself.
- When no listen address is specified, try to bind all
system address (both ipv4/ipv6).
- Send an alert to the peer on handshake failure, so that
the peer have some information on what happened.
- Consistency work accross all plugin logfile option.
- Various bug fixes and improvements.
