     * New LRG selection for SV with fewer bits.
     * New ``LOWZ_FILLER`` class for SV.
+    * Add LRG 4PASS and 8PASS bits/classes using cuts on ``FLUX_Z``.
     * New and simplified LRG selection for the Main Survey.
-    * Deprecate 1PASS/2PASS LRGs, all LRGs now have one pass.
+    * Deprecate Main Survey 1PASS/2PASS LRGs, all LRGs now have one pass.
     * Deprecate some very old code in :mod:`desitarget.targets`.

+    * New secondary output columns (``OBSCONDITIONS``, proper motions).
     * Add a cached file of primary TARGETIDs to prevent duplicates.
     * Create a more reproducible TARGETID for secondaries.
     * Automatically write secondaries split by BRIGHT/DARK.
     * Add option to pass secondary file in MTL.
     * Insist on observing layer/conditions for MTL:
