+Subject: [PATCH 2/5] plugin ntpdate: tolerate multiple NTP servers (e.g. in a
+ pool)
+
+Previously multiple "server" lines were consumed, but the output of the
+awk filter lacked the line ending. Thus the last numeric value of the
+previous "server" line was concatenated with the first numeric value of
+the following "server" line. Thus multiple dots occurred in a single
+numeric value and parsing just failed.
+
+Thanks, glyndon!

+Subject: [PATCH 3/5] Improve df
+
+Before, there were 1+n calls of df where n is the number of output values. I introduced some script magic to use the values from the
+first call. Motivation was, there was a very complex sed call which failed to process some of my df output lines. The new code is much
+safer.
+
+Actually, the original problem obviously was that the sed regex didn't cover capital letters which I had in my mountpoints.

+Subject: [PATCH 200/204] Allow customizing the list of monitored network
+ interfaces
+
+This is a simple way to customize the selection of network interfaces. If INTERFACE_NAMES_OVERRIDE is set in muninlite.conf, that list is used instead of auto-detection. As muninlite.conf
+itself is also a script, it is even possible to write a custom command.
+This feature is helpful in environments with virtual machines or containers, like docker or lxc where there are lots of br-*, veth*, lxcbr* etc interfaces where monitoring doesn't make much
+sense. I didn't find a way to reliably filter physical interfaces.
