* Added new contest macros to allow faster capture of outgoing exchange
* Added macro tag - puts fldigi into infinite transmit repeat of all text and tags preceeding . 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 , , , macros

Rig Control

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

o 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.
* Fixed lock-up problem when initial request for bandwidth fails
Associated with K3 rigcat failure
* Corrected K3 xml definitions for retrieving bandwith value, see K3.xml file
* Corrected hamlib initialization to correctly report failure when an active port is used, but which is not connected to the target transceiver.

Logbook changes

* change - Added new logging macro tag (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 (^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

* 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

o Changed to named store of last used mode in prefs file
o Added Contestia, Olivia, RTTY baud/bw values to prefs file.

* Abort ARQ

o Added call to AbortARQ when double ESC pressed (panic)
