We are upgrading from React 18 to 19 in Jira 12, Confluence 11, Bitbucket 11, Bamboo 13, and Crowd 8. React is a core frontend dependency in DC products, and it is also a dependency for other important frontend libraries such as Atlaskit.
The goal of this work is to keep DC products secure and compliant with our dependency policy, while also making it possible to continue upgrading other critical frontend dependencies in the future. Because of this, Marketplace apps using React will also need to upgrade to React 19.
Areas affected by this upgrade:
com.atlassian.plugins:reactweb resource will now provide React 19Clienside Extensions (CSE)will now use React 19
We encourage all app developers to use the shared platform web resource (com.atlassian.plugins:react) where possible, as it helps reduce bundle size and address security issues quickly with platform-wide patch rollouts.
As we learn more and develop tools to help with the migration, we will share our findings on the developer documentation.
If you have any comments, feel free to leave your feedback on the developer community announcement.
