2.16.17 (06-Dec-2020)

  *** Important note regarding FST4 mode: FST4 support is only partial.
  *** Accurate FST4 B4 checks and FST4 logging are fully supported.
  *** There is no Alerting for FST4 DXCCs, States, Grids, Prefixes, etc.
  *** There is no reporting of FST4 activity in the Mode Activity window.

  *** Includes Callsign database file version 2020-12-06 (2020-Dec-06)

  New Features:

    - Callsigns Display Grid: New online for text messages indicator, a filled
       square, can be shown in the top-right corner of the Callsign display.
       See the "Windows -> Text Messages" section of the Settings window.

    - Logging: New option to 'Log USA District "DC" as State "MD"'. This option
       is off by default. If enabled "DC" based stations will have their State
       converted from "DC" to "MD" and logged as "MD" regardless of the value
       returned from XML lookups and previous QSO lookups.

    - Command Line Parameter: "/myid=" a user defined string that will appear
       in the status section of the JTAlert titlebar text. This parameter is
       not used internally by JTAlert except for the status display.

    - WSJT-X Multicast UDP: Due to the unrelaibility in automatically
       determining which network interfaces are being used by WSJT-X for
       multicast UDP, JTAlert now has an explicit setting to indicate
       if WSJT-X multicast UDP is using a loopback interface. Ensure that
       the "Settings -> WSJT-X UDP Multicast on Loopback" menu is ticked.
       This applies for WSJT-X 2.3.0 -rc2 and later. The setting is
       ignored when using WSJT-X 2.2.2 and earlier.

  Changes:

    - US State Alert: "Consider DC as MD" setting moved from the "Rebuild
       Alert Database" section to the "Alerts -> Wanted US States" section
       of the Settings window. This setting is now titled 'Alert "DC" as "MD"'.
       When this setting is enabled, all "DC" stations will alert as "MD".

    - Decodes Windows: Online for text messages indicator symbol changed from
       a filled circle to a square.

  Fixes:

    - FST4: Callsigns not being displayed in the Callsign display and
       decodes not being displayed in the Decodes History window.

    - Decodes Window: Fatal error when changing the "Highlight excess DT"
       threshold value in the Settings when the Windows regional-settings
       utilizes a non-dot for the decimal separator.

    - Text Messages Window: Incorrectly being show at JTAlert startup
       despite the "Receive text messages ..." option being turned off.
