 ## Summary
 
-While the new TargetCategory class supports subtypes, only reading them is currently available; setting subtypes will be introduced in a future release.
+<!-- Here goes a general summary of what this release is about -->
 
 ## Upgrading
 
-* `TargetComponents` was reworked. It now is a type alias for `TargetIds | TargetCategories`:
- * `TargetIds` can be used to specify one or more specific target IDs:
-  * `TargetIds(1, 2, 3)` or
-  * `TargetIds(ComponentIds(1), ComponentIds(2), ComponentIds(3))`
- * `TargetCategories` can be used to specify one or more target categories:
-  * `TargetCategories(ComponentCategory.BATTERY, ComponentCategory.INVERTER)`
-* Dispatch ids and microgrid ids are no longer simple `int` types but are now wrapped in `DispatchId` and `MicrogridId` classes, respectively. This allows for better type safety and clarity in the codebase.
+<!-- Here goes notes on how to upgrade from previous versions, including deprecations and what they should be replaced with -->
 
 ## New Features
 
-* With the new `TargetCategory` class (providing `.category` and `.type`) we can now specify subtypes of the categories:
- * `ComponentCategory.BATTERY` uses `BatteryType` with possible values: `LI_ION`, `NA_ION`
- * `ComponentCategory.INVERTER` uses `InverterType` with possible values: `BATTERY`, `SOLAR`, `HYBRID`
- * `ComponentCategory.EV_CHARGER` uses `EvChargerType`: with possible values `AC`, `DC`, `HYBRID`
- * A few examples on how to use the new `TargetCategory`:
-    * `TargetCategory(BatteryType.LI_ION)`
-        * `category` is `ComponentCategory.BATTERY`
-        * `type` is `BatteryType.LI_ION`
-    * `TargetCategory(ComponentCategory.BATTERY)`
-        * `category` is `ComponentCategory.BATTERY`
-        * `type` is `None`
-    * `TargetCategories(InverterType.SOLAR)`
-        * `category` is `ComponentCategory.INVERTER`
-        * `type` is `InverterType.SOLAR`
-
+* `Dispatch.started_at(now: datetime)` was added as alternative to the `started` property for when users want to use the same `now` for multiple calls, ensuring deterministic return values with respect to the same `now`.
