 # Frequenz Python SDK Release Notes
 
-## Upgrading
+## Bug fixes
 
-- The `FormulaEngine` is now replaced by a newly implemented `Formula` type.  This doesn't affect the high level interfaces.  `FormulaEngine` is now a deprecated wrapper to `Formula`.
-
-- The `ComponentGraph` has been replaced by the `frequenz-microgrid-component-graph` package, which provides python bindings for the rust implementation.
-
-## New Features
-
-- The power manager algorithm for batteries can now be changed from the default ShiftingMatryoshka, by passing it as an argument to `microgrid.initialize()`
+- `FormulaEngine` and `FormulaEngine3Phase` are now type aliases to `Formula` and `Formula3Phase`, fixing a typing issue introduced in `v1.0.0-rc2202`.
