@@ -20,12 +20,18 @@ will consitute of a breaking change warranting a new major release:
 
 - Important bugfixes for PTME. See `q7s-package` CHANGELOG.
 
-# [v5.2.0] to be released
+# [v5.2.0] 2023-06-29
 
 ## Fixed
 
 - The firmware information event was not triggered even when possible because of an ordering
   bug in the initializer function.
+- Empty dumps (no TM in time range) will now correctly be completed immediately
+
+## Changed
+
+- PTME was always reset on submode changes. The reset will now only be performed if the actual data
+  rate changes.
