Cassandra 1.2.x EOL date

Evening list, Simple and quick question, can anyone point me to where the Cassandra 1.2.x series EOL date was announced? I see archived mailing list threads for 1.2.19 mentioning it was going to be the last release and I see CVE-2015-0225 mention it is EOL. I didn't see it say when the official
