- supports the new syslog protocol standards
- log statements can be embedded into each other
- the encoding of source files can be set for proper character conversion
- can read, process, and rewrite structured messages (e.g., Apache
webserver logs) using templates and regular expressions
- support for patterndb v2 and v3 format, along with a bunch of new
parsers: ANYSTRING, IPv6, IPvANY and FLOAT.
- added a new "pdbtool" utility to manage patterndb files: convert them
from v1 or v2 format, merge mulitple patterndb files into one and look
up matching patterns given a specific message.
- support for message tags: tags can be assigned to log messages as they
enter syslog-ng: either by the source driver or via patterndb. Later it
these tags can be used for efficient filtering.
- added support for rewriting structured data
- added pcre support in the binary packages of syslog-ng
- enabling mixed linking to compile only non-system libs statically
- lots of packaging updates to be able to build on RHEL4,5, Fedora9+ and be
parallel-installable with rsyslog and/or sysklogd on those platforms
- removing BR for flex & byacc to try to prevent files from being
regenerated
- fixing build error with cfg-lex.l and flex 2.5.4
- Fixed a possible DoS condition triggered by a destination port
unreachable ICMP packet received from a UDP destination. syslog-ng
started eating all available memory and CPU until it crashed if this
happened.
- Fixed the rate at which files regular were read using the file() source.
- Report connection breaks as a write error instead of reporting POLLERR as
the write error path reports more sensible information in the logs.
