Important bug fixes ​

  • Fix Bug disabled functionalities for interacting with components in the HUB from AP versions (4.7.0, 4.7.1, 4.7.2, 4.7.3, 5.0.0) affected by a bug in which saving shared components might delete local workspaces
  • Listing HUB spaces from affected AP versions will return the components as data objects, which don’t have the potential to trigger the bug, but limits the use of components.

New features ​

Data apps ​

Share data app deployments with "any signed in user" You can now share your data apps with every Hub user in your company with one setting. Data app deployments shared this way will be available in every user’s data apps portal.

Share data app deployments with external groups Sharing data app deployments with users from externally managed groups (e.g. LDAP/AD groups) is now available. This is done by either importing LDAP groups to Keycloak, or by connecting Keycloak to an external OIDC provider, which provides groups through the access token. Usage of such external groups is for sharing of data app deployments only. The actual users who run the deployments are still managed within KNIME Business Hub.

Data Apps Portal UX enhancements Enhanced the visual design and user experience of the data apps portal, enabling the addition of categories and descriptions to data apps. This enhancement allows data app consumers to effortlessly filter and identify relevant data apps based on their category and description.

Content Security Policy for data apps Admins of KNIME Business Hub can now set custom Content Security Policies for data apps, to restrict which resources, from where can be loaded into the data app’s user’s browser. See more in: Business Hub Admin Guide.

Deployments ​

Editing deployments Recreating deployments is no longer needed just to change their configuration.

Admin functionality ​

Backup / restore via Velero KNIME Business Hub is now complemented with the widely used, open-source backup / restore tool: Velero. You can mitigate the risk of serious data loss by setting up a backup schedule. The backup process does not require any downtime.

X-Frame-Options Header Now admins can also select from different X-Frame-Options header options, to prevent clickjacking attacks. See more in: Business Hub Admin Guide.

Security Improved security by removing sensitive information shown in the HTML source code.

Edge ​

KNIME Edge integration KNIME Edge 1.3 is now compatible with KNIME Business Hub 1.4.
