Statement of direction

[Long Term Support] Effective with the next IBM MQ Long Term Support release, clients should use a separately downloadable IBM Semeru Java runtime for IBM MQ client applications instead of using the Java runtime packaged with IBM MQ. IBM MQ intends to provide support for the IBM Semeru runtime via IBM MQ product entitlement when used for the purpose of running IBM MQ Java/JMS applications. The Java runtime packaged with the IBM MQ product is expected to be updated more often which might result in breaking changes for applications depending on it.

Delivery and support model

IBM MQ 9.3.0 follows the delivery and support model for IBM MQ that was introduced in IBM MQ 9.0. From IBM MQ 9.0, two release types are made available; a Long Term Support (LTS) release and a Continuous Delivery (CD) release.

[Long Term Support] The Long Term Support release is a recommended product level for which support, including defect and security updates, is provided over a specified period of time. This release is intended for systems which demand a long term deployment and maximum stability.

[Continuous Delivery] Continuous Delivery releases deliver new functional enhancements, in addition to fixes and security updates, on a much shorter cadence, so providing much more rapid access to those new functions. These releases are intended for systems where applications want to exploit the very latest capabilities of IBM MQ.

For further information see IBM MQ release types and versioning and IBM MQ FAQ for Long Term Support and Continuous Delivery releases.
