The corresponding videos would be included in the changelog/release announcement on the wiki and possibly also on the official main website, and/or the project's sourceforge page (not my call though)
We already have a number of videos created during the last 12 months, so it may also be possible to reuse some of those (for starters, we could collect some of those videos by going through the last 12 newsletters, and reposting the videos here)
I would suggest to look at videos like this one:
Things to highlight may for example include:
- new/improved aircraft
- new/improved airports/scenery
- new/improved UI (Qt5/Phi etc)
If there's more than person/group of people interested in helping with this, please try to coordinate your goals/focus using this thread (e.g. by stating the aircraft/airports you are going to cover in your video)
For the sake of simplicity, it may also be a good idea to use flight plans and/or fgtapes to reproduce certain flight segments, e.g. for different camera angles (think fgcamera).
