Update to 3.21.52 from 3.03, prepared in pkgsrc-wip by Makoto
Fujiwara, JA1XMS.  Committed during freeze to resolve build failures
of the old version, ok wiz@.

Upstream's NEWS covers only some versions, but:

= Fldigi 3.21 release notes =

== Bug fixes ==

  * Yes

= Fldigi 3.20 release notes =

== Modems ==

* Added new PSK-500 mode
* Added "robust PSK" modes: PSK-125R, PSK-250R, PSK-500R
* Added PSK63F mode, compatible with MultiPsk PSK63FEC
* Added Contestia support
* Added SSB "modem" to simplify logging of SSB QSOs
* Added MT63 modem preamble tones to aid signal acquisition
* Added selectable filter widths for Hellschreiber modes
* Added AGC and S/N detector for FM-HELL modes
* Added Olivia noise estimator

* Improved THOR and DominoEX squelch responsiveness
* Improved Olivia squelch detection
* Improved Feldhell AGC and S/N detector
* Improved RTTY decoder

* Removed THOR soft decoding
* RSID now works at the same time as modem decoding
* The HELL-80 tone spacing was changed to 300 Hz

== Macros ==

* Added <LOCK:on|off|t> macro to enable/disable/toggle the transmit lock
* Added <TUNE:nn> macro to transmit tuning tone for ''nn'' seconds
* Added <RXRSID:on|off|t> and <TXRSID:on|off|t> macros
* Added <WAIT:nn> macro to delay macro expansion by ''nn'' seconds
* Added <SRCHUP>, <SRCHDN>, <GOHOME>, <GOFREQ:nnnn> macros to search for a
  signal up and down in frequency, go to the "sweet spot frequency", and
  set the current modem frequency to ''nnnn''
* The <MODEM> macro syntax is now <MODEM:str>. The older <MODEM>str syntax is
  still supported.  Modem parameters may be specified when using the new
  syntax; currently for RTTY (shift, baud, bits), Olivia (bw, tones) and
  Contestia (bw, tones), e.g.: <MODEM:RTTY:170:45.45:5>, <MODEM:OLIVIA:500:16>,
  <MODEM:CTSTIA:250:8>.

== User interface ==

* The main window's QSO and waterfall toolbar are now much more configurable
* The QSO toolbar can now be set to Contest mode, Minimal mode, Full mode,
  and some combinations thereof
* The docked digiscope can be hidden and shown without a restart
* It is now possible to select the modes for which to transmit RSID, VideoID
  and CWID
* The Op Modes menu can now be customised
* Removed the floating rig control window
* Removed various Alt-<key> shortcuts
* Added a simple "wizard" for first-time users
* Added a waterfall-only mode; enabled with --wfall-only
* Removed option to use check buttons for AFC and SQL toggles

== Other changes ==

* The XML-RPC server now supports HTTP/1.1 keep-alive connections
* Added several new XML-RPC methods
* Renamed various main.set_rig_NNN XML-RPC methods to rig.set_NNN
* Removed obsolete command line switches: --twoscopes, --experimental
* Improved support for PulseAudio, now also the default backend on Linux
* The ^R string is no longer treated like ^r; it is now ignored unless at the
  end of the text to be transmitted
* The Portaudio playback stream is no longer kept open in receive mode; this
  fixes a problem with certain rig interfaces that generate a PTT signal even
  when the audio is complete silence
* Improved win32 serial port support

== Bug fixes ==

* The MT63 transmit buffer is now correctly initialized
* Fixed random exceptions-related crashes on win32
* Stabilized AFC for all PSK baud rates
* Improved sensitivity of RSID implementation

Many more small (and a couple not so small) bug fixes all over the tree
