= 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
