On http://dev.openstreetbrowser.org a new development version is available. Most changes were only bugfixes, like the icon chooser in the category editor which was next to unusable. But there are also some new features, e.g. a "debug toolbox" (enable it in the Options) which shows the status of the basemap tiles (later there will be more options). There were also updates to the new Translation system, it's now possible to add new tag-values (but not new tags right now) - please do so! Oh, and there were already updates to Czech language in the new system :)
