I think this may actually be legitimate confusion about version numbers. The version 0.52.3 that handaxe asks about is mentioned in a post from last month, but doesn't appear in openrepos list of rpms or in the changelog there. I suspect it's just a typo in MartinK's post -- and that v. 0.53.3 was meant -- rather than a version that appeared and slipped away some time in the past year.

Whatever the version, though, I'm always happy to see this app get updates, and I'm eager to try out the local OSM scout server option sometime soon(TM). Looks to be easier to manage local maps than in the N900 version of modrana -- I'm never quite sure I'm downloading what I need there. (Wish Scout Server had US units in addition to Metric and Imperial, but what's a fractional mm in a mile between friends, I guess. I'm not surveying, here.)
