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
• Added new contest macros to allow faster capture of outgoing exchange
•  Added <REPEAT> macro tag - puts fldigi into infinite transmit repeat of all text and tags preceeding <REPEAT>.  <ESC> terminates the loop
•  '^' Parser - Modified '^' character sequence parsing to eliminate idle character.  Beneficial for slow modem baud rates.
• Macro Mode Change - Change init_modem_sync(...) to init_modem(...) call in macro execute.  Macros are executed from main fltk thread.  The sem_wait call in _sync caused main thread to lock up.
• Added <ZT>, <ZD>, <LT>, <LD> macros
  

Rig Control

• RTS-DTR PTT - allow both to be used simultaneously with RigCAT control

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
• Is 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
• <ID> video text modified
• Combined 3 patches from kb3cs, added value (W1HKJ)
• Expanded video ID text for Olivia, Contestia and RTTY
• Amended macro editor <ID> explanation
• Changed format of auto-generated video ID text.
• Increased number of characters to 8 for both font sizes
• Simplified video generation methods
• Added limit switches on video width
• 500 Hz for US HF compliance
• Mode bandwidth, video constrained to mode in use bw
• Added abbreviated video mode name strings
• Added FEC indicator for DominoEX FEC modes
• Morse Prosigns
• Modified prosign / character translation
  
• Simplified morse table structure
  
• Print translated prosign character when transmitted
  
• Allow user selection of ')' or <AR> prosign both have same Morse representation
  
• Added style override for both put_rx_char and put_echo_char functions.  Allows prosigns to be display using CTRL style.
• Combo Widget - Changed size computation for popup browser
• Configuration dialog - change to "non-modal" to prevent being hidden by main window.
  

Logbook changes

•  <LOG> change - Added new logging macro tag <LNW> (Log NoW), which places the code pair "^L" into the transmit stream.  QSO logging takes place when that pair occurs in the transmit sequence.  This guarantees that the time of log will concur with the ^L occurance.  Changed tag parsing to always place <RX> (^r) as last control tag in the expanded text that is placed into the Tx buffer.
• Logbook Save - Fixed logic error in save record to logbook
• Logbook field sizes - removed all restrictions on field sizes
• Restored ADIF band computation
  

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
• Disable word wrap when file insert or drag-n-drop operation s performed.  Restore word wrap to former state after TX is finished or TX panel is cleared.
• Added user setting in seconds to allow RSID to open squelch in decoder.
• Changed default to Extended Characters for Olivia, Contestia and MT63
• Changed default to "Capture wrapped messages"
• Suppressed RSID transmit for unassigned RTTY, OLIVIA and CONTESTIA modes.
• Changed QRZ.com xml server page to "xml.qrz.com"
• Beginners Guide - Updated for new Lk and RsID button behaviors
• PH Cabrillo report generator - added SSB to USB, LSB, PH log entries which generate the PH Cabrillo report category.
• Modified xml generator for fldigi_def.xml to suppress xml key characters in the xml documentation block
• Mode prefs
• Changed to named store of last used mode in prefs file
• Added Contestia, Olivia, RTTY baud/bw values to prefs file.
  

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
• Pulse audio tx/rx flush blocking eliminated on Ubuntu
• RSID - Disabled signal search on init of psk modem, prevents jumping off of RSID detected frequency
• RSID - Resolve DominoEX / DominoEX-FEC modes
• Implement CLOCK_MONOTONIC on OS X
• Modify cty.dat lookup to account for special KG4 call assignments.  1 & 3 letter suffix in US 2 letter suffix in Guantanamo
• Re-enabled VideoID suppression
• Increased buffer size used for line input from file fldigi_def.xml
• RX-TX Select - Fixed text/background contrast for selected text in Rx Tx panels
  Added color selector for hightlight (SEL) color used in Rx/Tx panels
• Logger - Fixed bug in external log record introduced by 581a16c05d.
  This effects both Xlog and Gateway users.
• DXKEEPER log interface repaired
