Notes about Confluence 10 and Jira 11

Context

Confluence 10 and Jira 11 is a high-risk major release: The JDK 21 has changed base package names, which has impacts on practically every class. Atlassian has coordinated the update with the vendors, while taking this opportunity to perform a huge library upgrade.

  • Very few customers upgrade before the “LTS” version, which should be 10.2 in November,

  • We can’t test our integrations with the other apps until they, themselves, release a compatible version.

The risk is, however, less than the Confluence 9 / Jira 10 upgrade.

Risk assessment

  • We’ve tested the app on Confluence 10, all known features work well,

  • We expect unexpected issues,

  • We expect customers to upgrade late, after waiting for all other apps to deliver compatible versions, and letting other customers test first,

  • We expect that some customers will not be able to find compatible versions of other plugins. Those will be stuck on Confluence 9.2.

What we ask from customers

  • important Please test the upgrade on a staging instance,

  • important Please ensure all apps on your instance have a version available,

  • important Please be patient and tell us each issue. We’re prepared to be responsive, give us the opportunity to demonstrate it. If you are not patient, then please see the section “Our recommendation for conservative customers”.

How upgrades are presented

  • We keep publishing versions for Confluence 9.x (expecting 98% of the audience on 9.2 LTS),

  • For every version such as 4.3.6, we publish a 4.3.6-c10 which supports Confluence 10, marked as Confluence 10-only.

  • We haven’t removed other deprecated features such as Indexing v1.

Our support policy

We support LTS versions of Confluence for 2 years, which means:

  • Confluence 8.5 is not supported,

  • Confluence 9.2 will be supported until December 2026,

  • Confluence 10.0 started support in August 2025, and 10.2 will be supported until November 2027.

See our Compatibility matrix for version details.

Our recommendation for conservative customers

  • If you are still on Confluence 8.5, upgrade to Confluence 9.2 LTS,

  • If Confluence 10.2 is LTS and delivered in November, then upgrade to 10.2 in January 2025. All major issues will have been discovered, and January-February is a period of the year with low activity, meaning we will be able to polish any remaining issue.
