If you’re a Bitbucket Data Center app developer, use this page to keep track of upcoming changes, deprecation notices, new features, and feature updates.
In Bitbucket Data Center, we have moved the communication about releases and updates from the Atlassian Developer Community here. With this transition, we aim to provide partners and developers with a single, customizable feed of improvements and changes to our products.
We hope you will continue using the Atlassian Developer Community for discussion and support.
To continue getting updates about new Bitbucket Data Center releases, check out Bitbucket release notes.
We will continue posting updates to the Bitbucket Data Center category of the Atlassian Developer community. Subscribe to the category to stay tuned.
We are upgrading Jackson from version 2 to 3 in Jira 12, Confluence 11, Bitbucket 11, Bamboo 13 and Crowd 8.
The goal of this work is to keep DC products secure and compliant with our dependency policy while allowing upgrades during each major product version's supported period.
Areas affected by this upgrade:
The product system bundle provides Jackson 3 but not Jackson 2
Plugins using the system bundle's Jackson must migrate to Jackson 3. See the official Jackson 3 migration guide.
We shared the detailed migration steps in atlassian-rest UPGRADE_9_1_0.md.
If you have any comments, feel free to leave your feedback on the developer community announcement.
Bitbucket Data Center and Server 9.4.21 and 10.2.4 bug fix releases are available now!
To see the issues resolved in these bug fix releases, go to:
We are upgrading the design tokens to version 13.0.4 in all our upcoming DC product releases, including LTS versions.
The design tokens apply the visual foundations in Atlassian app experiences. This upgrade will result in a minor change in the visual style of affected products, especially icon colors, borders colors, and accent colors.
The main reason for this upgrade is to retain forward compatibility and consistency with newer versions of Atlaskit components.
Target releases:
Bamboo 12.1.8
Bitbucket 11.0.0 (10.2.0 provided the latest tokens to match Cloud; 11.0.0 removes the override and falls back to AUI)
Confluence 10.2.14
Confluence 11.0.0
Crowd 7.2.1
Jira 11.3.7
This change is delivered via AUI 10.2.0 (changelog).
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:react web resource will now provide React 19
Clienside 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.

We are upgrading from jQuery 3 to 4 in Jira 12, Confluence 11, Bitbucket 11, Bamboo 13, and Crowd 8. jQuery migrate will also be removed. Much frontend code depends on jQuery and we expect this will require upgrade work in apps (e.g. P2 plugins) and custom integrations with a frontend.
We consider this a breaking change and thus do not plan to backport to existing LTS releases.
This is to continue to meet customers' demands for secure & compliant products. We must be proactive in this upgrade because of how much our products and apps depend on it. We had many requests in the past to upgrade from jQuery 2 to 3, especially when there were vulnerabilities found in jQuery.
As we learn more and refine developer tooling to assist with the work, we will update the developer documentation
Many of the changes can be prepared for in a way that's backwards compatible with v3 so as many (compatible) changes as possible will also be backported to the LTS versions of Jira (11.3), Confluence (10.2), Bamboo (12.1) and to the latest versions of Bitbucket 10 and Crowd 7. The intention is to make it easier to test your app without having to worry about unrelated breaking changes.
Similarly, AUI 10.1 adds support for jQuery 4.
We will continue to provide jQuery web-resources and we ask developers to use them so that if needed we can roll out security patches as quickly as possible.
We are still early on in upgrading the Data Center products themselves. Future EAP versions will come with jQuery 4, but this might not arrive in the first few versions.
We have not currently noticed any JS behaviour nor signature changes that would affect apps. Please let us know if you spot something, and we will document it.

Bitbucket Data Center and Server 8.19.27, 9.4.16, and 10.1.4 bug fix releases are available now!

Data Center products support React 18 starting with the following versions:
Bamboo 12.0
Bitbucket 10.1
Confluence 10.1
Crowd 7.1
Jira Software 11.2
Jira Service Management does not bundle on its own copy
React 18.3.1 is provided by a bundled com.atlassian.plugins.react cross-product app that supersedes previous product specific React web-resources. React dependencies are exposed as AMD modules via the following web-resources:
com.atlassian.plugins.react:react-core-amd provides the atlassian/libs/react AMD module
com.atlassian.plugins.react:react-dom-amd provides the atlassian/libs/react-dom and atlassian/libs/react-dom/client AMD modules
com.atlassian.plugins.react:react-amd is a convenience bundle of React and ReactDOM above
Where applicable, existing React 16 web-resources are considered deprecated and will be removed in the next platform releases.
Additionally, we plan to upgrade to React 19 following the Atlaskit support as announced in https://community.developer.atlassian.com/t/rfc-78-dropping-support-for-react-16-and-rendering-in-a-react-18-concurrent-root-in-jira-and-confluence/87026/23
