• Fix: System uptime web tag for Linux systems - maybe!

• Fix: Historic charts wind run tooltip suffix

• Fix: High Min Temp and Low Max Temp records editors were not displaying and allowing input of the time

• Fix: This Month/This Year records editors were showing records for the entire day file rather than the specific period

• Fix: GW1000 station dewpoint calculation incorrect on first packet read at start-up

• New: Settings page: Program Settings. Moved Debug/Data logging options and Prevent Second Instance to here from Station Settings.
  Note: These settings still remain in the [Station] section of the Cumulus.ini file for backwards compatibility

• New: Two settings to delay the start-up of Cumulus MX. Both added to the new Program Settings page.
  Start-up Host PING: Specify a remote hostname or IP address, Cumulus will wait for a successful PING from this address before continuing
  Start-up Delay: Specify a fixed time in seconds to delay the start-up. The delay will be executed after the PING check is one is specified
  Start-up Delay Max Uptime: Specify a maximum system uptime in seconds after which the delay will no longer be applied. Set to zero to always delay
  New section in Cumulus.ini:
  [Program]
  StartupPingHost= // Default is no remote host - enter a host name or IP address
  StartupDelaySecs=0 // Default is no delay = 0
  StartupDelayMaxUptime=300 // Default is 300 seconds (5 minutes)

• New: FTP Now - Adds a new option to regenerate the daily graph data files (if enabled), and include them in the manually invoked FTP session

• New: Adds support for OpenWeatherMap uploads (and catch-up). Using an existing station if the id is supplied, or your API key only has one station defined.
  If no stations are defined CMX automatically creates a new one using your station details and starts uploading to it.

Build 3098 - Version 3.9.3

• Fix: Records check was triggering for very small value changes in derived values such as feels like temps

• Fix: Catch uncaught exception on SFTP disconnect

• New: You can now use "<airlinklogfile>" in the extra files local filename to copy/upload the latest AirLink data log file

• New: You can now define your Indoor AirLink as the primary AQ sensor. Note this only applies to the admin interface, its data will not be
  uploaded to the default web site

• New: Adds Cumulus MX update available alarm to the dashboard - enabled by default. This also has an associated web tag <#UpgradeAlarm>

• New: If enabled, the daily graph data files are now created at start-up and uploaded at first interval FTP.
  Previously you had to wait for the first EOD rollover.

• New: If a FineOffset station is not found, MX now dumps a list of all the USB devices it can see to the MXdiags log

Build 3097 - Version 3.9.2

• Adds Notifications to Alarms
  Note: Cumulus notifications only work by default if you run the browser on the same machine as Cumulus and connect using the
  url: http://localhost:8998
  In order to get them working on a remote machine you will have to change an advanced flag in your browser.
  This is at your own risk as advanced flags are unsupported features in Chrome and Edge.
  In Chrome or Edge, open the url - "about:flags"
  Find the entry "Insecure origins treated as secure" and enable it
  The add the url you use to remotely access the Cumulus dashboard - eg. http://192.168.1.23:8998
  Then click the button to restart your browser. Notifications should now work.

• Adds Latch times to Alarms. You can now specify a period in hours that an alarm will remain active after the event that tripped it has reset.

• The default value for "DavisIncrementPressureDP" is changed from true to false
  ** The effect of this is that for Davis VP/VP2 stations, the default number of decimal places used for pressure values changes
  from 2 dp (hPa/mb) and 3 dp (kPa, inHg) to 1 dp (hPa/mb) and 2 dp (kPa, inHg)
  ** If you wish to retain the previous behaviour, then you MUST add the setting "DavisIncrementPressureDP=1" to your Cumulus.ini file

• Fix: Last rain date not updating for Davis stations (fixes the mixed unit/bucket size update in 3.8.2)
• Adds two new Cumulus.ini file settings to control the numer of decimal places used for wind speeds. These override the built-in defaults.
  These settings are read-only, they can to be manually added ONLY if you need to use them. Add either or both settings as required.
  [Station]
  WindSpeedDecimals=[0|1|2]
  WindSpeedAvgDecimals=[0|1|2]
