The DPDD should be updated to make 2 changes :
1) Subsequent to the LSST Project Science Team's decision to adopt nano-jansky as the standard LSST flux unit(https://docushare.lsst.org/docushare/dsweb/Get/Document-27758), the description flux units (Section 2.3) of as well as the units in all tables must be updated to nJy
2) Addition of point estimates for photo-z in the Data Release Catalog Object table. These are described in Table 4: Data Release Catalog Object Table.
