Currently only Qt5 or above is known to work with this code. It may be
possible to backport it to Qt4 if required.
Audio output goes back to a separate thread to try and minimize
stutters in streaming on Windows particularly.
A crash on Linux due to mishandling of stereo audio output has been
fixed and both left and right channels are now correctly synthesised
with identical contents.
Rigs are enumerated directly from hamlib API rather than running a sub
process reading output of rigctl -l. This was initially done to get
rid of some GUI thread blocking in the configuration dialog, but is
generally a better way of doing it anyway.
Some refactoring in MainWindow to accomodate the audio streaming,
modulation and detecting classes.
Exit handling for application refactored to use signals rather than
brute force event loop exit. This was required to get correct thread
shutdown semantics.
The GUI update timer is now stopped during application shutdown which
is necessary to stop crashes when shutting down gracefully with
signals and window close() calls.
There is an outstanding issue with Linux audio streams; the QAudio
Input/Output classes create a new stream name each time a stream is
started. This doesn't play well with PulseAudio utilities such as
pavucontrol to set stream volume as settings are lost every tx
period. I have tried to keep a single stream for all output but there
are problems restarting it that haven't been resolved yet.
The QtCreator project file has been rearranged a little because it
passes all the object files to the linker rather than using an archive
library. Since the GNU linker is single pass; the object files need to
be in a logical order with definitions appearing afer references to
them. This was required to avoid a linking error.
The lib/Makefile.linux has been enhanced to use the fortran compiler
to locate the correct version of the Fortran library to use. This is
necessary on the latest Linux distros because the unversioned symlink
to compiler support libraries is no longer provided. This only an
issue with mixed programming language links where the linker driver
for one language has to link support libraraies for another language.

2. Minor adjustments to position of WideGraph controls.
3. Include the palette files. The whole directory "Palettes" should
be copied into the install directory.

Qt's built-in QAudio calls rather than PortAudio. Also includes some
refactoring of the arrangement for these calls, and more use of C++ style.

2. Double-click on a 73 message sets Tx5, rather than Tx6.
3. Clean up a few remaining compiler warnings.
4. Clean up Tab order.
5. Updates to User's Guide

platforms.
2. This might be temporary: set Audio output on unix platforms to stereo,
i.e., channels=2. On my Ubuntu system, at least, this makes it play
correctly on all of the relevant audio devices in the list, including
hardware and virtual (".asoundrc-implemented") devices.

2. SoundOut buffer size can be set by editing wsjtx.ini.
3. Fixed bug in placement of #ifdef in rigclass.cpp

2. Much better logic for choosing frequencies at which to attempt decodes.

decoder at the new frequency. CTRL-click (or CTRL-double-click) sets both
Rx and Tx freqs.
2. Amplitude at end of transmission is ramped down to prevent a "key click".

Compute samfac values; put them into "lab5" (for K1JT only).
Ransomize the rand() seed on SoundOutThread startup.
Increase the DT search range. (This still needs optimization.)

tests. Tx has been implemented.

MAP65 v2.3.0, r631, as checked out from the SVN repository on
pulsar.princeton.edu. If all goes well with this commit, subsequent
MAP65 development will use the Berlios repository.
