find_recent_changes
Read-only
Find CFR sections changed since a given date, removals included.
Built on eCFR's version history: every version issued on or after
since_date, newest first. Each change says whether the section was
amended, removed (change='removed'), or re-issued with no text change
(substantive=false). 'summary' counts each kind. A section changed
twice appears twice.
since_date must be in YYYY-MM-DD format. Filter with title (default 48),
chapter (Title 48: 1 = FAR, 2 = DFARS, 99 = CAS) or part. per_page
(default 100, max 5000) and page step through long lists; total_pages
says how many pages there are.
Common pattern: find FAR changes since a specific date to check for
regulatory updates that might affect ongoing acquisitions.
