Changes made from version 2.90 to 3.00:
*Added ability to select Venezuela and UTC time zones
*Added continuous altimeter auto calibration mode
*Improved altimeter auto calibration. Settings are now: Off, At Start or Continuous. Use 'At Start' for an initial calibration from GPS when tracking has started. This will result in more consistent relative elevation change. Use 'Continuous' to continually calibrate the barometer towards the current GPS elevation. This will result in a more stable elevation during pressure changes due to weather.
*Improved ETE/ETA calculations so they are more responsive to speed changes
*Fixed cadence units overlap in bottom data field
*Fixed issue with proximity alerts when GPS was off
*Fixed potential issue with alert notification settings
*Fixed issue where Track and FIT History details did not match for the same activity
*Fixed issue with Time -> Til Sunset alert
