Bamboo 11.0 upgrade notes
We’ve collected some important notes on upgrading to Bamboo 11.0. For details on all the new features and improvements we’ve introduced in this release, see the Bamboo 11.0 release notes .
Upgrade notes
Here’s some important information you should know about before upgrading.
All Bamboo nodes must run under the same user
In a clustered Bamboo High Availability (HA) setup with multiple nodes, it's essential that all nodes operate under the same single user account. This practice is crucial for mitigating potential security risks. Starting from version 11.0.0, Bamboo won’t function properly if this requirement isn’t met. Ensure UID and GID synchronization across nodes to prevent permission issues, especially in NFS or CIFS setups without local username mapping.
Migration to Struts 6
We’ve upgraded to Struts 6. Make sure you’re aware of the following changes:
Annotate getters with
@StrutsParameter(depth=X)(dependency onstruts-corelib)Annotate setters with
@StrutsParameter(dependency onstruts-corelib)The action method previously named
doSomethingmust now be fully informed. Previously, thedoprefix could be suppressed.The method previously named
getBamboo()has been renamed togetBambooContainer()to avoid warnings from Struts when.bamboo.is used in our templates.OGNL Allowlist.

Bamboo uses the AWS SDK V2 now
Bamboo AWS-related functionality, such as elastic agents and S3 artifact handlers, are now using AWS SDK V2, which replaced V1. This change was introduced to elevate your security and improve the performance and it should be invisible from the user perspective.
CodeDeploy Task was removed
After being deprecated for some time, the AWS CodeDeploy Task was finally removed from Bamboo due to compatibility and security concerns.
Legacy repositories API is removed
Bamboo 11.0 has removed the legacy repositories API. This change finalizes the transition to the modern API introduced in Bamboo 5.14, which included a rebuilt repository subsystem, new plugin points, and web repository viewers. This update eliminates technical debt and ensures a more streamlined and efficient system. Check out Bamboo API Changes for 5.14for more details.
Introducing Deployments Cache
Bamboo 11 introduces the global deployment projects and environments cache, which speeds up user interactions and background processing. We highly recommend having it enabled. However, the environments' cache can be disabled by setting the system property bamboo.deployment.cache.enabled to false.
Quiet period was removed
The quiet period functionality has been removed due to performance issues. Consider using the Stop oldest builds strategy for concurrent builds as an alternative. Explore more: Configuring concurrent builds | Bamboo Data Center 10.2 | Atlassian Documentation
Optional disabling of Change Detection for Branches from Forked Pull Requests
Bamboo now allows you to manage performance by optionally disabling change detection for branches created from forked repositories. This feature, enabled by the Create plan branch strategy set to Forked repositories are allowed, can impact performance. If you’re not using this functionality, we recommend disabling it to save resources. Set the system property bamboo.disable.bbdc.change.detection.for.prs.from.forked.repos to true to enhance Bamboo's performance by reducing the load on event workers.
