10/20/2013  -   Fixed serialization issue, where foursquare venues were not persisting with their id. This meant that any cached venue object would not equate to a venue object retrieved from a live search, and the venue callout would not appear. Backward compatibility issue addressed by checking for platform specific id in JSON before deserializing recently viewed venues from the persisted data file. Fixed venue callout issue where most recently selected venue callout was not re-expanded after interface switch (page change).
10/20/2013  -   Fixed issue where concurrent venue refresh threads were not properly cancelled before subsequent spawns. Re-enabled current location mechanism on map interface. Fixed refresh map logic to use relative search radius rather than fixed 100 meters at the default zoom. Slight flicker occurs on venue callout expansion when navigating from the highlight interface. This is due to a double refresh, need a way to kickstart venue animations without refreshing the entire map.
