I've made a video exploring the new features and changes in LibreOffice
5.3. Note that this video is UNLISTED, so please don't share it around
with everyone -- it's just intended for use inside the LibreOffice
project, so everyone has a good overview of the changes.
Based on this, I will make more polished (and shorter) New Features
videos in early January, that we can then share with everyone, add to
our website and so forth.
Anyway, I hope you find it useful!
