**This is testing release only!**
This is fairly big release. Important highlights:
* (experimental) new note type "relation map" for visualizing relations between notes
* new concept of "mirror" relations - relation can require another relation in the opposite direction
* we now parse out note content "links" - e.g. hyperlink from one note to another, image reference or inclusion of note in the relation map. These links are also visible in the relation map.
* images are now represented as "image" notes, i.e. they are placed into a tree structure
* there's a migration script which puts the image under every note in which it is placed
* jQuery UI removed completely from the application, using mostly Bootstrap (upgraded to v4) to replace its functionality
* consolidated icon usage, moved to [Jam icons](https://jam-icons.com/) (previously used mix of feather icons, custom icons, glyphicons and jQuery UI icons). Jam icons look remarkably similar to feather icons so overall look stays very similar
* Experimental [Evernote import](https://github.com/zadam/trilium/wiki/Evernote-import)
**Because of changes in image representation, synchronization protocol changed and all instances in sync cluster needs to be upgraded at the same time.**
