Along with the release of v2.1.1, HPDC is updating the HPD Builder, the online tool that most manufacturers and preparers use to create HPDs. There is a short time period between the Release of v2.1.1 and the full Implementation of it, to accommodate this.  The Effective date—the date on which any newly published HPD will need to use v2.1.1—will be timed with the availability of the HPD Builder.

The HPD Builder update will include a feature enabling automated conversion from v2.x HPDs to v2.1.1.
