The support time frames for the software event broker versions in PubSub+ Cloud are different from the PubSub+ software event brokers releases. The support dates, upgrade availability dates (if supported), and planned releases are summarized on the Support Dates for Release Versions page. However, if you want an understanding of the differences, see Types of Releases in PubSub+ Cloud.
Releases prior to 9.11 do not follow the current PubSub+ Cloud release cadence and software event broker version adoption policies. For this reason, those releases have different expiry dates for full and technical support.
For details about the release cadence, differences between releases, and support phases for PubSub+ Cloud, see Version Adoption in PubSub+ Cloud.
