PLEASE SEE THIS BLOG POST FOR A MUCH NEWER AND UP-TO-DATE OVERVIEW:
The Oracle Lifetime Support Policy brochure for tech products has been updated now as well in order to reflect the addition and availability of Oracle Database 12.2 on-premises:
Please note that this table and the brochure never makes a distinction between patch sets and base releases. For instance, the line talking about Oracle 11.2 does not say that Oracle Database 220.127.116.11 is out of any bug fixing support since Aug 27, 2015 – and Extended Support only applies to Oracle Database 18.104.22.168. For those details please refer to the MOS Note 742060.1 mentioned below the table (and please refrain from asking me why this information is not included – open an SR and raise this with Oracle Support).
The most important note in MOS, 161818.1, has not been updated yet but should reflect the dates soon as well.
