 # Frequenz Python SDK Release Notes
 
+## Summary
+
+<!-- Here goes a general summary of what this release is about -->
+
 ## Upgrading
 
-- The minimum required version of `frequenz-microgrid-component-graph` is now `0.3.4`.  This reverts the formula generation to what it was like before the migration to the external component graph library.  So
-    * in component formulas, meters get used as primary sources and inverters, ev chargers, etc. as fallback sources.
-    * consumer formula are generated by excluding producer and battery powers from the grid power, or when there is no grid meter, by adding all the non battery and producer meters.
+<!-- Here goes notes on how to upgrade from previous versions, including deprecations and what they should be replaced with -->
 
 ## New Features
 
-- The SDK's data pipeline now supports retrieving telemetry from CHPs.
+<!-- Here goes the main new features and examples or instructions on how to use them -->
 
 ## Bug Fixes
 
-- Fixed an off-by-one calculation in `OrderedRingBuffer.count_covered` by switching to integer timedelta division, ensuring accurate sample counting for all window sizes and sampling periods.
-- Component IDs are validated during creation of battery, pv and ev charger pools, so that errors are caught early and we don't end up getting cryptic failures from somewhere else.
