-The current TMD 2.1.1 version differs from the 2.0.0 version only
-slightly in the national weights (all the `WT*` columns in the
-`tmd_weights.csv.gz` file and just the `s006` variable in the
-`tmd.csv.gz` file); the non-weights input variables in the
-`tmd.csv.gz` file and the contents of `tmd_growfactors.csv` file are
-unchanged.  When using version 2.1.1 to generate **sub-national
-weights**, there will be (presumably small) differences from the
-sub-national weights generated using version 2.0.0; however, the
-sub-national weights fingerprints have not yet been updated.
