 2.5.0 (Upcoming)
 ---------------------
 
+Major changes
+^^^^^^^^^^^^^
+- Shape of SpatialSeries.data is more restrictive to prevent > 3 columns. (#510)
+
 Minor changes
 ^^^^^^^^^^^^^
 - Added an ``offset`` attribute to all ``TimeSeries`` objects to allow enhanced translation to scientific units.
+- Updated ``TimeIntervals`` to use the new ``TimeSeriesReferenceVectorData`` type. This does not alter the overall structure
+  of ``TimeIntervals`` in a major way aside from changing the value of the ``neurodata_type`` attribute in the file
+  from ``VectorData`` to ```TimeSeriesReferenceVectorData``. This change replaces the existing ``TimeIntervals.timeseries``
+  column with a ``TimeSeriesReferenceVectorData`` type column of the same name and overall schema. This change facilitates creating
+  common functionality around ``TimeSeriesReferenceVectorData``. This change affects all existing ``TimeIntervals`` tables
+  as part of the ``intervals/`` group, i.e., ``intervals/epochs``, ``intervals/trials``, and ``intervals/invalid_times``. (#486)
 - Clarified the doc string for the ``reference`` column of the electrodes table. (#498)
 - Added ``cell_id`` field to ``IntracellularElectrode``. (#512)
