# The weekly fitness API roundup

> A roundup of each ISO week in fitness and health APIs, generated from this site's records at every build: tracker changes, graveyard shutdowns and launches, SDK and library releases, and the pages first published here. Only records dated to the day are placed in a week; anything dated by month or year stays in the monthly digest. A week needs 3 records, one of them from outside this site, to get a page; 8 weeks do.

## How the roundup is made

- Tracker entries come from src/data/changes.ts, graveyard dates from src/data/graveyard.ts, releases from hcReleases.ts, sdkReleases.ts and libraries.ts (each package's latest publish only, so a week can undercount a busy package), and new pages from src/data/published.ts.
- A record whose source gives only a month or a year is never placed in a week. A date after the build day is never placed either.
- A graveyard date that a tracker entry reports for the same page on the same day appears once, as the tracker entry.
- Week pages are noindex: the monthly digest is the indexed archive of the same records. The feed and the links are what the weeks are for.
