Hi all,
for the interested ones, have push the current state to my repo which
can be found in here -->
https://git.ipfire.org/?p=people/ummeegge/ipfire-2.x.git;a=commit;h=34af1d714178b2cd0c27e8c39052a8c7ce87d116
feel free to test and criticize it :-) .

After integration and configuration, the 'save' button in the global
section should also be pushed since --cipher will replaced by --data-
channel-fallback. For the langs files, a update-lang-cache should be
executed via console so the changes can take affect.

Happy testing. Best,

Erik
