-	        Release: WSJT-X 2.5.1
+	        Release: WSJT-X 2.5.2
+	             Oct 29, 2021
+	        ----------------------
+
+This is mostly a bug fix release.  It has the following changes since
+release 2.5.1:
+
+ - Repair a longstanding regression that caused signal reports from
+   tail-ended Tx2 messages to be omitted from logged information
+
+ - Repair a regression associated with setting the main window width
+   on program startup.
+
+ - Repair a problem with Q65 decodes of type 'q3' for messages of the
+   form "<Call_1> Call_2"
+
+ - Implement Q65 decodes of type 'q3' for the message "TNX 73 GL".
+
+ - Execute code associated with Q65 decodes of type 'q5' only when the
+   Max Drift control is set to 50.  This fix prevents
+   double-incrementing of the message averaging counter on the first
+   decoding sequence.
+
+ - Polarization offset 'Dpol' from the asronomical data window is now
+   written to file azel.dat if environment variable
+   WSJT_AZEL_EXTRA_LINES has been defined. Dpol is especially useful
+   for EME on the higher microwave bands.
+
+ - New hamlib code to correct minor flaws in controlling several rigs
+
+ - Update the Chinese and Hong Kong translations of the user
+   interface.
