+                      Release: WSJT-X 2.7.0-rc5
+                             July 1, 2024
+                      -------------------------
+
+WSJT-X 2.7.0 Release Candidate 5 introduces a new "SuperFox" mode, a
+powerful new tool designed to help DXpeditions make digital QSOs at
+very high rates. RC5 also brings several other improvements and bug
+fixes.
+
+SuperFox mode:
+
+ - The SuperFox mode behaves operationally like the present Fox and
+   Hounds mode but uses a constant envelope waveform for Fox's
+   transmissions rather than sending concurrent streams of up to five
+   normal FT8 signals. This approach means that up to 9 messages can
+   be transmitted with no signal-strength penalty, resulting in a
+   system gain of about +10 dB compared to the conventional Fox/Hound
+   operation with 5 slots.
+
+ - IMPORTANT: Older revisions of WSJT-X and derivative programs cannot
+   decode SuperFox transmissions. Hounds must use WSJT-X 2.7.0-rc5 (or
+   a later release, when available) to be able to receive SuperFox
+   messages.
+
+ - Hounds chasing the DX station transmit normal FT8 signals, as in
+   the already familiar Fox and Hound mode.  QSOs are logged as FT8
+   mode.
+
+ - When in SuperFox mode, Hound stations may call at any frequency in
+   Fox's received passband, including the range 0 - 1000 Hz.  Hounds
+   do not QSY to a lower frequency for their final transmission.
+
+ - SuperFox Operation requires the Fox operator to use a valid digital
+   key.  Keys will be issued in advance for legitimate DXpeditions by
+   the Northern California DX Foundation, and will be kept secret.
+
+ - Every SuperFox transmission includes a unique digital
+   signature. Hounds receiving a SuperFox message will see a "CALLSIGN
+   verified" flag if the transmitted signature is valid, and the
+   on-screen "Super Hound" label will turn from red to green.
+
+ - Hound operation should begin by selecting "Special operating
+   activity", "Hound", and "SuperFox mode" on the Settings -> Advanced
+   tab. Alternatively, right-clicking on the FT8 button toggles
+   SuperFox mode on/off for either Fox or Hound, allowing quick
+   transitions between SuperFox and old-style Fox and Hound operation.
+
+ - SuperFox stations can send free text messages of up to 26 characters
+   together with messages to as many as 4 Hounds.
+
+Other enhancements:
+
+ - Corrected a flaw that caused "Log automatically" to not work for
+   the ARRL Digi Contest.
+
+ - Control elements for special operating activities are now disabled
+   (grayed out) if the respective function is not applicable.
+
+ - Corrected a longstanding flaw that caused "Start new period
+   decodes at top" to stop working properly after some time.
+
+ - Right-click mouse press events are now less error-prone.
+
+ - Improved the readability of the first line when "Start new period 
+   decodes at top" is checked.
+
+ - 4-digit grids are now logged for certain contest modes to ensure that 
+   the log complies with the contest rules.
+
+ - The Fox Tx frequency is now saved and restored separately.
+
+
