Looks like there are no additional bug reports for the last version (0.15.0). @mal started making Finnish translation and is getting close to finishing it. As soon as its ready, I can release an update.

As for User's Guide, I think the current structure is ready for translators. So, if anyone is wishing to translate that, please fork OSM Scout Server repo and add translation directly under docs/langcode and follow the lead under "fr" or "en". Its a lot of work though, taking into account large amount of screenshots needed for it.
