0.4.2 --> 0.5
   - Configuration has changed, gpsk31 now uses the more convenient GKeyFile
     format. The location of the default configuration file now is at
     $HOME/.gpsk31/gpsk31.cfg. The global configuration file is no longer used.
   - Configuration is now handled through the Preferences dialog (ctrl+P
     or Window->Preferences from the menu). Some changes to the preferences
     require a restart.
   - Changing of the font color in the TX window now works correctly.
   - There was a compilation fix for version 2.4 of GTK+.
   - gpsk31 is now licensed under the GPL version 3.

0.4.1 --> 0.4.2
   - Contributions by Thomas Ries, HB9XAR:
   - QSO dialog: Empty "Freq" field passes "HAMLIB" to xlog (xlog shall
     take current frequency from TRX). Can be controlled via new config option
     "xlog_auto_freq" (1 enabled, 0 disabled)
   - Filter out CTRL characters from TX Window (currently CTRL-[a-z])
     Annoying when trying to clear content of the window (CTRL-a, CTRL-x)
     Better would be a "Clear Window button or entry in RMB context menu.
   - Added a TCP socket interface to receive/transmit data from a
     3rd party application (contest-bot?).
     Config option "tcp_listen_port" defines the port number where
     gpsk31 will listen for a connect. Only one single concurrent 
     connection is supported. Setting tcp_listen_port = 0 disables
     this feature. 
   - New commandline option (-c <configfile>) to load a specific 
     configuration file. If used, the config file name is displayed
     in the window title. One can pass just the name of the config file
     (then gpsk31 searches in $HOME/.gpsk31) or including a full (absolute)
     path name.
   - Fix: frequency axis (spectrum/waterfall) does now correspond with
     actual value (which varied with "spectrum_width" setting)
   - F-Keys also work for sending macros if QSO dialog window has focus

0.4 --> 0.4.1
   - Code cleanups.

0.3.4 --> 0.4
   - Another contribution by Thomas Ries, HB9XAR. gpsk31 now comes with a
     waterfall display. See the README on details how to use it.

0.3.2 --> 0.3.3
   - The following command line options are now accepted: -v: output version
     number and exit, -d: enable debugging.
   - All of the windows and dialogs now have an icon.
   - There were many code cleanups. gpsk31 now requires version 2.4 of GTK+.
   - The following changes by Thomas Ries, HB9XAR.
   - Fixed sending the "~mx" macros over the air.
   - A line marking the center frequency added.
   - QSO Details Dialog: immediately convert Call to uppercase (so macros
     will send it in upercase).
   - Fixed labeling of the frequency (it was assuming a center frequency of
     always 1000Hz).
   - Make ~t~r within the same programmed text work ("~t xxx ~r" did not
     turn off the sender after finishing).
   - Set the QSO start time when transferring the QSO to Xlog, not when
     clicking "New".
   - If you are using a gpsk.conf in $HOME/.gpsk31, you will need to add a
     line with 'spectrum_center_line_color = "color"', for example:
     'spectrum_center_line_color = "#808000".

0.3.1 --> 0.3.2

   - Prevent a buffer overflow when reading the config file. Thanks to
     Fernando, LU2DFM for reporting.
   - Several compilation warning fixes for gcc-4.3.
   - All of the Glib and GTK+ deprecated widgets and commands are removed
     from the code.

0.3.0 --> 0.3.1

  - CW ident should work now.
  - In order to prevent a clash in the shurtcuts Ctrl+f is now used for
    "Log to File" and Ctrl+e for "Frequency".

0.2.4a --> 0.3.0

  - The program now exits of it can't open the audio device.
  - gpsk31 is ported to version 2 of the GTK+ libraries.
  - The config file has been renamed gpsk.conf, so it this version does not
    read obsolete settings.
  - The config file now uses fonts strings like "courier 12 bold" instead
    of "-adobe-courier-bold-r-normal-*-*-120-*-*-m-*-iso8859-1".
  - We now use the SHIFT key to access the extra fix texts. Pushing the control
    key plus a function key would conflict with certain window-managers.
  - GUI cleanups: menus and statusbars have been cleaned up, all non-working
    items were removed.
  - The latest psk31 routines are copied from the twpsk-2.2beta1 source tree.
  - Logging now works with xlog. When the xlog button is clicked in the QSO
    details window, the QSO data will be sent to xlog.
  - A help dialog has been added. It displays the README.
  - Gnome menu entry, rpm spec file and application icon added.
  - Several minor bugfixes.

0.2.4 --> 0.2.4a
  
  - Now I include DL9RDZ's new Version (0.10).
  - Some bug fixes in the macro_processor function.
  - Now we have 16 Fix Texts :-).
  - now, you can fine scroll, even during RX/TX.

0.2.3 --> 0.2.4

  - File send now implemented.
  - Log to file should work.
  - A new menu: Send (You can send the fields of the qso dialog).
  - A new menu: Modes (You may use this menu to change the operating mode).
  - Fixed memory leak.
  - Phase Scope sensitivity is now increased (makes it easier to tune weak
    signals (PU1JTE).
  - Startup size is now 640x440 Pixels.
  - Modified configure script. Now datadir is configurable.
  - Removed gtkrc/fx.txt config file. Now we have ONE gpsk31.conf for all
    settings.
  - Improved macro_processing.
  - Some Bug fixes.

0.2 --> 0.2.3

  - Ported the while thing to DL9RDZ's new functions.
  - Betted DCD (DL9RDZ). Level can be adjusted by using the scalebar between
    the Phase scope and Spectrum.
  - New RX Sync/Filter (DL9RDZ) See globals.h.
  - Added PTT over com port (DL9RDZ) See globals.h.
  - Now we have a statusbar :) .
  - Removed auto scaling spectrum. Spectrum now configurable (see globals.h).
