 # [unreleased]
 
-# [v6.0.0] to be released
+# [v6.0.0] 2023-07-02
 
+- `q7s-package` version v3.2.0
 - Important bugfixes for PTME. See `q7s-package` CHANGELOG.
 
-# [v5.1.0] to be released
+## Changed
+
+- Added back PTME busy bit polling. This is necessary due to changes to the AXI APB interface
+  to the PTME core.
+
+## Fixed
+
+- For the live channel (VC0), telemetry was still only dumped if the transmitter is active.
+  Please note that this fix will lead to crashes for FW versions below v3.2.
+  However, it might not be an issue for the oldest firmware on the satellite (v2.5.1).
+
+# [v5.2.0] 2023-07-02
+
+## 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.
+- Add back ACS board code for the EM. Now that the radiation sensor was removed, the image switching
+  issue has disappeared and adding back the ACS board is worth it for the GPS timekeeping.
+
+# [v5.1.0] 2023-06-28
 
 - `eive-tmtc` version v5.1.0
