This documentation is intended for Confluence developers who want to ensure that their existing plugins and add-ons are compatible with Confluence 5.5, and to learn about the new features for developing add-ons in Confluence 5.5.
Confluence is now using AUI 5.3.4. See the AUI release notes for information on what's new in AUI 5.3.
We are in the process of developing a new REST API for Confluence. Our existing APIs will be deprecated over time, as equivalent resources become available in the REST API. We recommend plugin developers use the REST API where possible.
See Confluence API for more details.
The Confluence caching infrastructure has been updated to use the Atlassian Cache version 2 API. This API is backwards compatible with the previous version (0.1) of the Atlassian Cache used by Confluence.
Plugin developers can create a cache specifically configured to their plugin requirements. See How do I cache data in a plugin?
Confluence's source distribution includes the source of the internal Atlassian projects that Confluence depends on (such as , ). From this release onwards, these internal Atlassian dependencies are now Maven-based archives, rather than exports of the source repository for each dependency. There will be a Maven-based archive for each dependency, named <dependencyname-version>-sources.jar. Please note the following:
We are working to improve our clustering solution and expect to make it available later this year. Confluence 5.5 will not include a clustered artifact, and customers wishing to set up a cluster in production will need to continue to use Confluence 5.4. A developer milestone (Confluence 5.5-m22) of our work so far is available to developers who want start working to ensure their add-on is cluster compatible. See How do I ensure my plugin works properly in a cluster?.
See Confluence 5.5-m22 EAP Release Notes for more details of changes to clustered Confluence including:
Milestone releases for developers
Please watch the Development Releases page for pre-release versions of Confluence 5.5 that you can use for testing purposes.
If you have any questions about preparing for Confluence 5.5, please register for an account on Atlassian Answers, our community Q&A resource, and ask a question. We'll be keeping an eye on things to help out as soon as possible.
