Changes

Change tracking

Track text changes between archived captures. These changes reflect differences between snapshots, not current guidance.

Descriptive changes only

Comparisons highlight text differences between archived captures. They do not interpret meaning or provide medical guidance. For up-to-date recommendations, always consult the official source website.

For citation guidance, see /cite.

Scope

View digest & RSS

The default view is edition-aware and reflects changes between archived captures, not real-time source updates. Annual editions are captured on Jan 01 (UTC), and ad-hoc captures are labeled when they occur.
