       Release: WSJT-X Version 1.9.0-rc4
                 April 26, 2018
        ---------------------------------

Changes from WSJT-X Version 1.9.0-rc3 include the following:

- Corrected a number of flaws in Fox and Hound behavior, FT8
  DXpedition Mode

- Decoded CQ calls where a prefix has been used as a suffix should
  have the DXCC entity name assigned correctly in almost all cases

- Improved AFC capability for the wider JT65 sub-modes to help with
  drifting signals

- Better support for macOS using hi-DPI Retina displays

- New UDP message that allows external applications to highlight
  decoded callsigns

- Main-screen geometry and state of the "splitter" setting between its
  two text windows is now properly restored after program restart.

- New simulator jt49sim[.exe] replaces jt4sim and jt9sim

- Correct S/N measurements for the JT9 slow/wide submodes

- Other minor bug fixes

- Updated copy of cty.dat

おそらく、主だった変更はDXペディションモード関連。

ということで、見た目の変化はなさそう。
