+Core interface changes
+~~~~~~~~~~~~~~~~~~~~~~
+
+Probabilistic regressors and time-to-event predictors now have an ``update`` method.
+The ``update`` method is the unified interface point for incremental fitting strategies,
+such as online learning, efficient re-fit strategies, or Bayesian updates.
+
+Whether a non-trivial ``update`` method is implemented depends on the specific estimator,
+this can be inspected via the ``capability:update`` tag of the estimator.
+
+Estimators without a dedicated ``update`` method, that is, those with
+``capability:update=False``, implement the trivial ``update`` where no update
+is performed, with the internal estimator state remaining unchanged.
