Blueprint 6.0

Blueprint 6.0

Blueprint 6.0 is now available (as of June 2025). It focuses on the removal of deprecated and legacy code and the modernization of the codebase.

Breaking changes overview

Global changes

• CSS namespace changed from bp5- to bp6-.
• React 16 and 17 are no longer supported as peer dependencies of Blueprint.
• Blueprint no longer produces UMD bundles from its packages.
• Switched out the implementation for the following deprecated components. With each of these components the versioned component has replaced the unversioned variant and the versioned variant is exposed as a deprecated alias of the original component. For example, the previously deprecated <PanelStack> component is now implemented using the <PanelStack2> implementation and API. Users can still use PanelStack2 but it is now identical to using PanelStack. The name PanelStack2 is deprecated and will be removed in an future major version bump.
