Zoph 0.9.15 released

This release fixes a few bugs, finalizes the update of the slideshow, bringing back the navigation buttons and added 'swiping' to aid into optimizing the working on touch devices.

I've also started on a request that has been outstanding for a very long time: adding XMP support to Zoph, to aid into interworking with other applications. It's very basic now, please see XMP in the documentation. If you are planning on using this in your workflow, please let me know what you're missing!

The full changelog can be found in the changelog. You can download Zoph from the Gitlab site.
