+3. Made all documents accessible from the top level namespace
+=============================================================
+
+Date: 2024-10-03
+
+Status
+------
+
+Accepted
+
+Context
+-------
+
+We should make all documents importable from the top level event-model namespace. We should be able to `from event_model import Limits` rather than `from event_model.documents import Limits` or `from event_model.documents.event_descriptor import Limits`.
+
+
+Decision
+--------
+
+Accepted
+
+Consequences
+------------
+Repositories downstream will be able to simplify their imports.

 Release History
 ***************
 
+v1.22.0 (2024-10-02)
+====================
+
+Changed
+-------
+* Added a `NX_class` field as a `PerObjectHint` to the `EventDescriptor` document.
+* Removed `Optional` on `DataKey` fields `precision`, ``choices``, and `units`. These fields can still be left out of the `DataKey`, but if provided they cannot be `None`.
+* Added a `Limits` type for storing EPICS limit data and a `NotRequired[Limits]` `limits` field to `DataKey`.
+* Added a `NotRequired` `dtype_numpy` field to `DataKey` for specifying the numpy dtype of data.
+* Bumped from `jsonschema 3.*` to `jsonschema 4.*`.
+* Added all documents to `event_model` namespace.
+
 v1.21.0 (2024-05-21)
