[syslog-ng] syslog-ng-3.23

[Laszlo Budai]

3.23.1
======


## Features

 * The `redis()` destination now handles any number of command parameters.
   (#2816)

 * The `format()` option of `date-parser()` supports lists. From now on, a
   single `date-parser()` instance is able to process different date formats,
   making it easy to catch on when some programs change the way they log
   information. (#2779)

 * Add relocation support for `disk-buffer()`. The `relocate` subcommand of
   `dqtool` can be used to move a single or multiple queue files. (#2855)

 * `file(), pipe()`: The `time-reap()` option now can be set or disabled for
   each destination separately.
   Use `time-reap(0)` to disable closing idle destination files. (#2798)

 * `syslog-ng-ctl`: Add `list-files` subcommand to print files present in the
   current configuration. (#2797)

## Other changes
