Delivery and support model
IBM MQ 9.4.0 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]](nglts.gif)
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]](ngcd.gif)
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.
