Changelog

A dated, authority-labelled feed of the rule changes and official notices behind the Portugal Data Ledger — every AIMA notice, tax measure, legislative amendment and social-security update that touches a fact we publish, logged with its date, its issuing authority and a link to the primary source. When any of these changes, we re-verify the underlying fact before we update the data — nothing is published automatically. Newest first; filter by authority or search the feed.
