This release introduces a new feature into the mixing workflow, by allowing the admin to configure default-source-combinations for the existing composition modes (#80). This allows for a smoother operation in a usual conference environment. Please be aware, that in the next release the workflow will be further streamlined with the upcoming Scene-Buttons (#29). They will obsolete this feature.

The Fullscreen-Buttons now have Shortcuts, too (#72) but this will also be obsolted with the introduction of Scene-Buttons. Also, in the UI the close-button moved to the right side of the toolbar (#79).

The Y-Position of the Side-by-Side-Equal Videos is now configurable (#71) but similarly the Scene-Buttons will introduce a new way to configure compositions.

The Main-Output, usually used for recording, now has a bigger buffer-limit to fix broken recordings, because of the recording-script slowing down too much with problematic image-content (d136edd).

The core now shows which config-files it tried to parse and which ones succeeded (#85).
The Command-Server can now give introspective help by using the help command (#59).
The deinterlacer in the preview-pipeline is now configurable (5870698).

Some work has been done to the example scripts, adding a new source-all-videotestsrces.sh script and simplifying the configuration of the example-scripts with a custom config.sh. There are now example-Scripts for Playout to the Framebuffer (#70) and recording all the incoming audio-streams as a backup (#64). Also we now have example-systemd-units for running the various scripts needed to build a complete pipeline (#48).

@Florob contributed a script which maps midi-devices (foot-pedals, drum button-pads etc.) to voctocore control-server command (#89).

Also numerous spelling and wording issues were corrected and updates the documentation and screenshots, thanks to @ritjoe and @saerdnaer.
