So far as we can determine, all indicators have been redefined from a diffusion index with a central value of 100 to a balance of opinion. Unchanged is that the consumer confidence index is the average of the five questions numbered P3 to P8. The start date is unchanged.

In response, we have:

1. Archived the predecessors by renaming with an "_03" specifier, marking metadata as"discontinued", and segregating in the catalog.
2. Otherwise refurbished the metadata, including the unit-descriptor. (It incorrectly denoted a fixed-base index relative to 2003.)
3. Created one-for-one replacements.
