+`6.1`_ -
+-------------------
+
+Fixed:
+
+- template_double_seq_pcomp: Fixed a bug in the standard design that allowed
+  an extra trigger to be sent to detectors in stack scans. A logical AND
+  was added to the Live Frame and Dead Frame LUT blocks from the Seq Enable
+  SRGATE. **Existing scan designs should be updated with this change too.**
