 # pygnssutils Release Notes
 
+### RELEASE 1.1.7
+
+ENHANCEMENTS:
+
+1. gnssntripclient will now tolerate an NTRIP 1.0 response to an NTRIP 2.0 request if the caster only supports NTRIP 1.0, or vice versa.
+1. gnssstreamer now supports both NTRIP 1.0 and NTRIP 2.0 clients via the `-rtkntripversion` flag (previously it assumed NTRIP 2.0).
+
 ### RELEASE 1.1.6
 
 FIXES:
