Rsyslog is an enhanced multi-threaded syslogd.
Among others, it offers support for on-demand disk
buffering, reliable syslog over TCP, writing to
databases (MySQL, PostgreSQL, Oracle, and many
more), email alerting, fully configurable output
formats (including high-precision timestamps), the
ability to filter on any part of the syslog
message, on-the-wire message compression, and the
ability to convert text files to syslog. It is a
drop-in replacement for stock syslogd and able to
work with the same configuration file syntax.

Changes:
The primary new feature is support for (optional)
mutual authentication in TLS mode. This is based
on IETF's upcoming syslog-transport-tls standard
in certificate fingerprint authentication mode.
Other than that, there are a couple of bugfixes.
The is a recommended update for all users of the
development branch. Please note that TLS support
is still quite experimental and not recommended
for production use.
