What's New
A reader-facing summary of recent improvements, and how the atlas stays current
Quick Answer
The atlas is versioned explicitly — the current version and build date appear on the home page and in the footer, and the version is stamped into every page's citation line so a reference always pins the edition you saw. This page summarizes recent improvements in plain language; the complete, dated technical changelog ships with the source.
Recent highlights
The most recent work has focused on interaction quality and content trustworthiness:
- Consistent, comfortable dark mode. Hover, input, badge, and inline-code styles were reworked so text stays readable in both themes, with contrast verified by measurement rather than by eye.
- Topic browsing that works. The home-page topic chips (PET, SPECT, Therapy, Cardiac, Oncology, Neuro, Pediatric, Tools) now open a grouped, tappable list of matching pages instead of only filling the search box.
- Overlays you can always dismiss. The A–Z index, command palette, study mode, and help panels all close consistently by Escape, by their × button, and by clicking outside — so you are never stuck in a dialog.
- Verified citations. Clickable DOIs are added only after each is confirmed to resolve to the stated paper; citations are never guessed.
- Site information pages. About & Methodology, Editorial Policy, How to Cite, Privacy & Data, Accessibility, a FAQ, Contact, and this page round out the reference's transparency layer.
How the atlas is maintained
Confirmed corrections are applied promptly, the affected page's last-updated date is advanced, and substantive changes are recorded in the version history. Content aging is tracked by an automated health check that surfaces the oldest and least-reviewed pages, so staleness is visible rather than hidden. See Editorial Policy for the sourcing, grading, and correction standards, and Feedback & Corrections to suggest an improvement.
