 ## [1.17.0] - 2025-03-21
 
+### Changed
+
+-   Changed `ICommandProcessorFactory`, `ICommandHandlerFactory` and `CommandProcessor<>` to be 
+ registered as transient rather than singleton. This allows `CommandHandler` implementations to use 
+ dependencies registered as scoped.
+
+-   Reintroduce `IProjectionFactory` in a slightly modified version to allow consumers to make additional "initialization" of projections.
+
+## [1.17.0] - 2025-03-21
+
 ### Fixed
 
 -   Ensure that a projection can run in its own scope. This is important as we do not want state to leak from one projection to the other.
