INSTALLATION:
./configure --enable-threads --enable-xft
for shared libraries use
./configure --enable-shared --enable-threads --enable-xft
Before compiling fldigi be sure that you have the latest Fltk source tarball downloaded, compiled and installed. Please do not use precompiled Fltk libraries unless you know that they have been created with the above configurations switches.

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

· < 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
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 "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.
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
