Over the past ~15 years, IBM has been releasing DB2 on a very strict cadence: every 2 years, in October [complementary information].
IMS 14 was GA in October 2015, thus we expect IMS 15 to go GA in October 2017.
Since IBM announced Continuous Delivery Model for DB2 12, we can also expect that IMS 15 will use similar “Incremental” approach.
Simply said, we are awaiting IMS 15 GA date, to turn IMS Tools r19 “Full GA” (aka. “Mature”), and start IMS Tools r20 “incremental”.

IMS Tools r16 : End-of-Service for r16 was announced and will be effective on 31st March 2017. Customers still using r16 need to upgrade soon to either r18 or (preferably) to r19.
IMS Tools r17 : This release never existed. We skipped this release number (and jumped to r18) as a mean to “synchronize” IMS Tools and DB2 Tools release numbers some years ago.
IMS Tools r18 : End-of-Service for r18 was not yet announced, but will be announced when releasing the first PAX file for IMS Tools r20 (in ~October 2017), with 12 month notice.
?Aka. IMS Tools customers using r18 should be upgrading, either r19 or r20, by ~October 2018
