Geocache Versioning ?
=======================

Currently trying to load an old geocache into new code asserts::

Solution for now is to recreate the geocache by running with "-G".
In future may want to introduce versioning (could be as simple as a version.txt file containing a number).
Then can notice geocache with version incompatible with code and auto recreate the geocache.
