There is rc142(based on rc142_6), we are going to share to the wide trial on November 14th around 09:00 UTC.

Changelog:
- FT4: sliding DT synchronization window is implemented to take in account a latency of RX audio stream (SDR and remote receiver setups, setups with bad computer clock sync).
  +/- 1.1sec by default, +/- 1.4sec for SWL functionality. Initial DT window (at start of program) is -1.0..+1.4sec by default, -1.2..+1.7sec in SWL mode.  
- cty.dat file is updated to version CTY-2915, LoTW users file is updated
changed source files: cty.day, decoder.f90, ft4_decode.f90, ft4_mod1.f90, ft8b.f90, lotw-user-activity.csv, mainwindow.cpp

There is rc142_5, changelog:

- DX Grid window data shall be checked for 'new grid' notification if grid for DX Call callsign is absent in QSO history and message with grid is not received.
  Grid will be stored in QSO history from DX Grid window upon CQ (no grid) or 73/RR73 message received from DX Call callsign, then 'new grid' notification will be using grid from QSO history   
  This functionality is dedicated to users who prefer to enter manually or from CALL3.TXT file grid data in the DX Grid window to check if grid is new one. 
- DX Grid window shall not be populated from log for /MM /M /AM /P /A callsigns
- average DT being used for RX sync sliding window shall be displayed in UI above the 'Band Activity' window
changed source files: adif.cpp, decoder.f90, displaytext.cpp/h, mainwindow.cpp

2019.11.06

There is rc142_4, changelog:
- added protection to prevent getting out of ss33() array bounds in agccft8.f90, defect is in rc142_3
- FT8: sliding DT synchronization window is implemented instead of the static one to take in account a latency of RX audio stream (SDR setups, setups with wrong computer clock sync).
 DT sync window:  +/- 2.5sec by default, +/- 3.5sec for late start of decoder and SWL functionality
- bug is fixed in TCP QSO logging debug 
changed source files: agccft8.f90, decoder.f90, ft8_decode.f90, ft8_downsample.f90, ft8_mod1.f90, ft8b.f90, logqso.cpp, sync8.f90

2019.11.04

There is rc142_3, changelog:
- FT8 AGC compensation functionality is reworked: taking less CPU cycles and shall be automatically skipped 
if AGC operation is not detected in the current interval
- improved FT8 decoder sensitivity while AGC compensation is in operation
changed source files: agccft8.f90, decoder.f90, ft8_mod1.f90, sync8.f90

-------------------------------------------------------------------------------------------------
2019.11.02

There is rc142_2, changelog:
- improved FT8 decoder sensitivity while AGC compensation is active 
- patch to the directional CQ functionality & autoselection broken in rc142_1
- patch to avoid empty distance: distance to correspondent with 8-char grid shall be calculated for 6-char grid
changed source files: displaytext.cpp, ft8_downsample.f90, ft8b.f90, ft8_decode.f90, mainwindow.cpp, 
                      ft4_downsample.f90, get_ft4_bitmetrics.f90

-------------------------------------------------------------------------------------------------
2019.10.29

There is rc142_1, changelog:
- TX messages addressed to callsigns which prefixes start from "CQ" letters shall be correctly handled by AutoSeq
- added FT4 signal simulator
- improved sensitivity of FT4 decoder(with no respect to AGCc button setting)
- added tooltips in Notifications tab of the settings to RR73/73 and Markers & Other standard messages checkboxes

changed source files: CMakeLists.txt, Configuration.ui, decoder.f90, displaytext.cpp, ft4_downsample.f90, ft4_mod1.f90, get_ft4_bitmetrics.f90
added new source files(also added to svn): ft4sim.f90
