 * refactor: refactored `SurrogateLearner` and `SurrogateLearnerCollection` to allow updating on an asynchronous `Archive`.
 * feat: added experimental `OptimizerAsyncMbo`, `OptimizerADBO`, `TunerAsyncMbo`, and `TunerADBO` that allow for asynchronous optimization.
 * feat: added `AcqFunctionStochasticCB` and `AcqFunctionStochasticEI` that are useful for asynchronous optimization.
-* doc: minor changes to highlight differences between batch and asynchronous objects related to asynchronous support.
