 # Release Notes
 
-## Summary
-
-New `Quantity` types! These types can have units (power, current, voltage, etc.) and are *type- and unit-safe* in the sense that users can't accidentally sum a power with a voltage, or a power in kW with a power in W.
-
-## Upgrading
-
-- `Sample` objects no longer hold `float`s, but rather `Quantity` or one of its subclasses, like `Power`, `Current`, `Energy`, etc. based on the type of values being streamed.
-
-  ```python
-  sample: Sample[Power] = await battery_pool.power.new_receiver().receive()
-  power: float = sample.value.as_watts()
-  ```
-
-- `BatteryPool.soc` now streams values of type `Sample[Quantity]`, and `BatteryPool.capacity` now streams values of type `Sample[Energy]`.
-
-  ```python
-  battery_pool = microgrid.battery_pool()
-  soc_sample: Sample[Quantity] = await battery_pool.soc.new_receiver().receive()
-  soc: float = soc_sample.value.base_value
-
-  capacity_sample: Sample[Energy] = await battery_pool.capacity.new_receiver().receive()
-  capacity: float = soc_sample.value.as_watt_hours()
-  ```
-
-- `MicrogridApiClient.set_power` no longer returns a `protobuf.Empty` result, but a `None`.  This won't affect you unless you are using the low level APIs of the SDK.
-
-## New Features
-
-- The logical meter has a new method that returns producer power, that is the sum of all energy producers.
-
-- `Quantity` types (`Power`, `Current`, `Energy`, `Voltage`) for providing type- and unit-safety when dealing with physical quantities.
-
 ## Bug Fixes
 
-- Two bugs in the ring buffer which is used by the `MovingWindow` class were fixed:
-  - `len(buffer)` was not considering potentially existing gaps (areas without elements) in the buffer.
-  - A off-by-one error in the gap calculation logic was fixed that recorded a gap when there was none if an element with a future timestamp was added that would create a gap of exactly 1.
-
-- A formula engine lifetime issue, when creating higher order formula receivers without holding on to a reference to the engine, was fixed.
+- Fix formatting issue for `Quantity` objects with zero values.
