+[v2.0.3][] - 2019-12-01
+-----------------------
+
+### Changes
+- Always run `domark()` timer, regardless of `-m interval` setting,
+  it is used for internal housekeeping, runs every 15 sec
+- Handle DNS lookup of unknown remote syslog hosts in `domark()`
+- Only enable debug mode when `-d` is given on the command line
+- Always create PID file, even in debug mode
+- Add `-F`, as alias for `-n`, to klogd for compat. with syslogd
+
+### Fixes
+- When logging to a remote host using @FQDN previous releases of syslogd
+  gave up after 10 tries.  In many industrial cases intermittent access
+  to the DNS is very likely, so this release includes a fix to retry the
+  IP address lookup forever.  The interval for retries is configurable
+- Fix accidental blocking of SIGHUP/SIGALRM when an invalid facility is
+  found in the internal `logmsg()` function
+- Fix leaking of internal error messages (like DNS lookup failure) to
+  `/dev/console` during reconfiguration, i.e. after initial start
+
