Signalizing "New map available" or "You have latest release"

I bought your Locoins nad downloaded OSM vector map for the Czech Republic.

The map is noted "2014.09" and the creation date is 2014-08-31.

There is no ability to check (or auto-check) for new release of this map in Locus. One may try to delete and redownload :-(

So few questions: Will there be a new version of OSM maps? Why they are so old?

Did you think about auto-notification about possible update?

Could be update of the map more simple (new button probably in map details)?

Thank you for your work.
