Index of Changes
A Quick Reference of Effective Rule Filings
The Index of Changes (Index) documents effective rule filings for the previous calendar year. Before 2021, the Index was published as a PDF file. Since 2021, the Index has been published as an XLSX spreadsheet, which provides greater flexibility in the usage and presentation of the data.
