 ### Enhancements
 - Added support to append to a dataset of references for HDMF-Zarr. @mavaylon1 [#1157](https://github.com/hdmf-dev/hdmf/pull/1157)
+- Adjusted stacklevel of warnings to point to user code when possible. @rly [#1166](https://github.com/hdmf-dev/hdmf/pull/1166)
+- Improved "already exists" error message when adding a container to a `MultiContainerInterface`. @rly [#1165](https://github.com/hdmf-dev/hdmf/pull/1165)
 
 ### Bug fixes
 - Fixed bug when converting string datasets from Zarr to HDF5. @oruebel [#1171](https://github.com/hdmf-dev/hdmf/pull/1171)
@@ -14,6 +16,8 @@
 - Added new attribute "dimension_labels" on `DatasetBuilder` which specifies the names of the dimensions used in the
 dataset based on the shape of the dataset data and the dimension names in the spec for the data type. This attribute
 is available on build (during the write process), but not on read of a dataset from a file. @rly [#1081](https://github.com/hdmf-dev/hdmf/pull/1081)
+- Speed up loading namespaces by skipping register_type when already registered. @magland [#1102](https://github.com/hdmf-dev/hdmf/pull/1102)
+- Speed up namespace loading: return a shallow copy rather than a deep copy in build_const_args. @magland [#1103](https://github.com/hdmf-dev/hdmf/pull/1103)
