  • Display update during logger download can be turned off
  • Fix incorrect 'rain since midnight' value if Cumulus restarted on first of month

    • <#forecastnumber> is always set even if Cumulus forecast not in use
    • <#cumulusforecast> - always gives Cumulus (Zambretti) forecast
    • <#wsforecast> - always gives station forecast (if available)
    • <#HighWindrunRecordSet> (=1 if 'all time high wind run' LED is lit, otherwise 0)
    • <#wetbulb>
    • <#timeUTC>
  • Don't plot wind chill until first value calculated
  • Don't reset rain counter if Davis logger doesn't go back far enough to fill the gap since previous run
  • Change La Crosse station forecast to 'Clear' instead of 'Sunny', at night
  • Today's dominant (i.e. average) wind direction (in degrees) added to dayfile.txt
  • New 'dominant wind direction' web tags.
  • Heating and Cooling Degree Days added to dayfile.txt
  • New heating/cooling degree days web tags:
  • NOOA-style monthly and annual reports
  • Internet uploads are now on the hour and every N minutes after, if the supplied interval is a factor of 60.

  • Corrects a few tooltips
  • Prevents a crash in the dayfile.txt editor if dayfile.txt doesn't exist
  • Fixes a bug in the dayfile.txt editor which caused the 'create missing' facility to miss certain days


  • Fixes a problem with monthly rain calculation at start up for people who use an 0900 start of day


  • Shows number of logger entries downloaded for WMR200 stations
  • Support for pond sensor for WMR88/100
  • Background colour of data value digits on main screen can now be configured
  • New web tag <#IsSunUp> gives 1 between sunrise and sunset, otherwise 0


  • Fixes <#IsSunUp> web tag
  • Error log window now has 'clear' button
  • Attempt to fix problem of La Crosse rain counter calculation going negative


  • Correct wind chill decode on WMR88/100/200
  • Encode colon as &3A in PWS Weather upload timestamps, to see if unencoded was causing a problem with 'catch up'


  • Reduces default height of NOAA report displays so that the controls are available on smaller screens
  • Correct 'days of rain' counts on NOAA annual reports
  • Correct max rain amount and date on NOAA annual reports
  • Increase precision of pressure sent to WOW/WU/PWS


  • Fix <#IsSunUp> time zone problem
  • Fix Davis 'wake up' issue so AltimeterPressure reported to CWOP doesn't get stuck at the same value
  • NOAA reports now label the 'days of rain' with '<=' to match what the code actually does
  • New web tags:
    • <#DavisFirmwareVersion> - The console firmware version (Davis stations only)
    • <#TempChangeLastHour> - The change in temperature over the last hour. The value can also be seen on the main screen as a 'mouseover' on the temperature trend value
    • New web tags giving the recent wind bearing extremes: <#BearingRangeFrom>, <#BearingRangeTo>, <#BearingRangeFrom10>, <#BearingRangeTo10>


  • Stops the dayfile.txt editor crashing if an empty dayfile.txt exists
  • Fixes a problem with rain rate calculation on La Crosse stations when logger data is used


  • Fix WS23xx apparent temperature values at start up
  • Fix WMR100 (etc) 'last data read' in status bar, and also allow 'data stopped' detection
  • Option in cumulus.ini to stop new Longest Wet/Dry Period records being 'flashed'. Add a line to the [Station] section:

  • Fix 'wind bearing range' web tags when wind is/has been calm
  • Fix negative (°F) temperatures in wxnow.txt


  • Fix high gust bearing in 'create missing' facility in dayfile.txt editor
  • Use configured filename format for manual saves of NOAA annual reports

    • <#cumulusforecastenc> - the same as <#cumulusforecast> but with all reserved HTML characters, and those above character code 159, encoded as HTML entities

  • Put time of last rain tip as a mouseover on today's rain total on main screen
  • Allow Cumulus pressure trend names to be used with Davis stations if the station won't supply its own strings (it seems the original Vantage Pro won't)
  • Allow plots on Select-A-Graph to be assigned to the left or right axis. This allows two items to be compared when they have large differences in their scales, e.g. UV and solar.


  • Fix bug with download of logger data from Fine Offset with solar sensor when station is logging to first address
  • One or both grids can be turned off on Select-A-Graph
  • Fix wind chill read from WMR88/100/200 when less than 0 Fahrenheit
  • Added a bit more diags logging at start up


  • Prevents a crash in the USB code at start up on some systems
