What actually changed
An entry appears here only after BuildRules can point to the official source, identify the affected jurisdiction and explain the practical consequence.
No confirmed change entries published yet.
That is deliberate. BuildRules will not label a source refresh, page redesign or new review date as a regulatory change unless the evidence supports the claim.
