This file describes the change history for dplus

v 2.1c:   Fixed problem where streamcache entries were depleted by missing
          end of stream packets from users.  Changed the way the info urcall
          works to allow querying of link status.  If you now use "XXNYYY I"
          as urcall (where you substitute your repeater callsign), it will
          play /dstar/tmp/id.dvtool if not linked and if linked it will play
          /dstar/dv/remotesystemlinked.dvtool.  Added a status file as
          /dstar/tmp/status that shows the current status of dplus.  The
          status file shows dplus version, connected dongle users, and
          linked modules.

v 2.1b:   Added support for up to 10 reflectors.  Needed for REF005-6.

v 2.1a:   Fixed dongle user reporting glitch.

v 2.1:    Added support for linking new multi-gateway reflectors.  Fixed
          some collector logging code for reporting dongle users to
          dstarusers.org.  Added the ability to link and unlink from the
          Linux command line on gateways.  Examples:
              echo "REF001CL" >/dstar/tmp/link-b
                  to link your local module B to reflector module C
              echo "       U" >/dstar/tmp/link-b
                  to unlink your local module B from any gateway/reflector
          Do not link multiple local modules to the same remote module.  You
          can link local modules to separate remote modules on the same or
          different reflectors/gateways.  As with 2.0, you cannot link the
          same local module to multiple remote gateways/modules.  This avoids
          undetectable linking loops.  Use the reflectors for this function.

v 2.0:    Support for G2 release of Icom gateway software.  Split the table
          reading function out to a separate executable dplus-readdb which
          creates text files /dstar/tmp/gateways.txt and /dstar/tmp/users.txt.
          These files are created hourly by execution of dplus-readdb by
          dplus.  Files /dstar/tmp/extragateways.txt and extrausers.txt
          are downloaded during installation and when dplus is started
          using "service dplus start".  These extra files are no longer
          updated since they include version 1 gateway data only.
          Restart dplus using "service dplus restart" and stop with
          "service dplus stop".

v 0.104:  Added linking to reflectors and other gateways.  Only one link can
          be made from a module at a time (but each module can link to another
          reflector or gateway).  Urcall is used to link with "XXNXXXML" for
          linking and "XXNXXXMU" or "       U" for unlinking (where XXNXXX
          is the remote reflector or gateway callsign, "M" is the module you
          are linking TO, and L or U is for linking or unlinking).  Note
          that dplus.conf has a new control field "allowadminlinkingonly"
          which, if set to 1 will allow only those in the "adminusers" section
          to link and if set to 0 will allow any user to link.  If
          "linknotifyminutes" is set to a non zero value, an announcement
          will be played after the indicated number of minutes using
          /dstar/dv/remotesystemlinked.dvtool for audio.  DV files added
          to the /dstar/dv directory are:
              alreadylinked.dvtool
              alreadyunlinked.dvtool
              gatewayunknown.dvtool
              reflectorunavailable.dvtool
              remotesystembusy.dvtool
              remotesystemlinked.dvtool
              remotesystemunlinked.dvtool
          Also added is the ability to specify the ethernet device for
          internal and external interfaces using internalethernet and
          externalethernet fields in the dplus.conf config section.
          If you are manually installing dplus, get "dplus", "dplus.conf",
          and "dplus-audio.tgz".  Extract dplus-audio.tgz into /dstar/dv.
          Brian (NJ6N) has an automatic installer that can also be used.

v 0.103:  Added dongle user authentication via MNG file lookup.  This prevents
          admins from having to add every user with a pin to allow transmit.
          If a user is not registered in the gateway, the admin will have to
          add them to the dplus.conf file to permit transmit.  This provides
          the fix for the "what if a dongle user isn't a ham" problem.

v 0.102:  Fixed parsing partial MNG file.  This had the potential to cause
          a buffer overflow.

v 0.101:  Added the ability to allow all users to transmit via the dongle
          using "*;;rw" in the allowedusers section of the dplus.conf file.
          This is the first release candidate for version 1.0 of dplus.

v 0.100:  Added dongle support configuration and more gateway linking code
          gateway admins may now configure the maximum number of dongle
          users as well as which users may connect and transmit on their system.
          Added "XXNXXX I" urcall value to request playback of gateway ID if
          if exists in /dstar/tmp/id.dvtool.  You can record your repeater ID
          by running an echo test "XXNXXX E", say your repeater ID, and then
          move the file /dstar/tmp/echo.dvtool to /dstar/tmp/id.dvtool.  This
          is a good companion to the echo test so you can now see how well you
          are hearing the repeater.
          Place dplus.conf in /dstar/tools along with dplus and edit to taste
