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.

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.

the main GUI thread (thanks to G4WJS).
2.. Also, for the record, some example code for using QAudioInput instead
of PortAudio. This code is not presently active, and will need to be
changed to accommodate the changes in #1, above. But the basic ideas
are here...

submitted by G4WJS.
2. Improved(???) means of multiple tries when polling radio for frequency.
3. Minor tweaks to widget sizes on devsetup screen.

Use ptt_() function included in getfile.cpp.

2. Added option to retain between QSOs the Comments field for ADIF and
wsjtx logs.

2. Removed all vestiges of NB code and controls.

memory region smaller by some 150 MB.)
2. Some code cleanup (removing unused lstrong, etc.)...

2. Re-establish the pxdb measurement for Thermo.
3. Double-click on decoded line copies it to QSO window (unless it's
already there).

is now a button. It is enabled only when Orange, which means CAT
control is essentially Program to Radio only. Clicking the button
causes a one-time read of the radio's dial frequency.

I have changed the declarations of the Rig class functions we use:
open()
setConf()
getFreq()
setFreq()
setPTT()
close()
... so that each one returns the (negative) error code returned by
hamlib. These functions no longer throw exceptions.
Initial tests seem to show things working well. I have found one
condition that causes a crash. The rig is initially opened and is
running OK (in this case, with the Polling interval set to 1 s). Then
the radio is turned off. The next call to getFreq() never returns.
Probably we need to set a timeout limit?
The code is kinda on the quick-and-dirty side. Improvements will be
welcom!

2. Rationalize tab-order on main window.
3. Tweak the GUI appearance around DxCall, DxGrid. (Hope it's still OK
in Linux!
4. Add helpful displays of Keyboard Shortcuts (F3) and Special Mouse
Commands (F4).
5. Bump version number to 0.95.
6. Update the Windows packaging script.
7. Update ChangeLog in preparation for possible release of v0.95 r3226.

functions.
2. Restored "Test CAT Control" and "Test PTT" buttons on the
Setup | Configuration screen.
These features need thorough testing!
