+version: 1.0.0
+description: "Spamhaus DROP feed connector — pull the 'Don't Route Or Peer' lists (hijacked/leased netblocks and ASNs used by cyber-criminals) and emit normalized IOCs (CIDR or ASN + type, with SBL reference) for import into the Threat Indicator Manager. Free, no authentication required; stdlib-only, no extra Python dependencies."
+changelog: "1.0.0 — Initial release: fetch DROP (IPv4), DROPv6 or ASN-DROP as normalized indicators."
