Is there any official document that outlines the date till which MySQL Community Server 5.7 will receive security updates/patches? I see that page 20 of this document from Oracle outlines Premier and Extended Support end date for MySQL 5.7, but I am not sure if it is talking about Community Server Edition or MySQL Enterprise Edition. Is there a relation between extended support end date listed in the document and the date till which MySQL 5.7 will receive security patches?
Also, are security fixes released to Community Server first and then hardened and released to Enterprise edition of same MySQL version? Or are they released to Enterprise edition first and then to Community Server edition?
Short version of my question: Till what date will MySQL 5.7 Community Server get security patches? :)
