+- New class :class:`.Dataflow` for describing input and/or output data flows (:pull:`300`) that are read from file and attached to a :class:`.Computer`.
+  Generalized from former :py:`.transport.files.ExogenousDataFile`.
+- New method :meth:`.Config.regions_from_scenario` (:pull:`300`),
+  extracted/generalized from :meth:`.transport.Config.from_context`.

-- Recompute :attr:`.minimum_activity` for transport technologies.
+- Drop some :attr:`.minimum_activity` entries; recompute values and add to :data:`.act_non_ldv`.
 - Improve freight representation:
 
   - Adjust freight activity, freight and passenger mode shares for some regions.
   - Add dynamic constraints on activity of freight technologies.
   - Fix alignment of freight technology outputs with demand |l|.
+  - Add :data:`.elasticity_f`, analogous to :data:`.elasticity_p`.

+  - Add :py:`scenario` dimension to :data:`.activity_ldv`, :data:`.lifetime_ldv`, input data flow and files.
 - Expand use of fixed/shared keys from :mod:`.transport.key`.
+- Improve documentation:
+
+  - Expand documentation of :doc:`input data flows <transport/input>` to include *all* input data flows.
+  - Document some :doc:`output data flows <transport/output>`.
+- New operator :func:`.indexer_scenario`.
