 2.7.1 (unreleased)
 ------------------
 
+* Fix `pkg_resources`, `scipy.ndimage`, and `pytest` deprecation warnings [`PR #829`_].
 * Add `GAIA_` prefix to `PHOT_*_MEAN_MAG` column names [`PR #827`_].
     * So GD1/streams files conform to downstream data model.
 * Module file removed vars that are now defined in desimodules:
