Changelog (KNIME Business Hub 1.12)

KNIME Business Hub 1.12.2

(released November 26, 2024)

Important changes (please read carefully)

  • KNIME Business Hub 1.12.2 addresses default memory requests across multiple services. This helps lowering the minimum hardware requirements, so that Business Hub can again be deployed on machines with only 32GB of memory (while allowing an executor with at most 12GB RAM). Customers with larger machines do not need to go to this version.

  • This release introduces the ability to configure hardware resource requests for the additional services in the KOTS admin console. At the same time, default memory requests have been reduced for these services:

  • Search-sync service: 2560MB → 1024MB

  • Artemis: 2048MB → 1024MB

  • Elasticsearch: 2048MB → 1024MB

  • Memory requests for istio-proxy sidecar containers have been reduced from 128MB to 64MB per container

  • This setting will only be applied after relevant pods have been restarted via kubectl rollout restart deployment -n hub. Doing so is not strictly necessary, but will save around 2.5GB of memory combined

KNIME Business Hub 1.12.1

(released September 11, 2024)

Important changes (please read carefully)

This release fixes wrong default values for CPU requests for various services. These values were introduced in KNIME Business Hub 1.12.0, and led to resource issues on smaller clusters.

For instance, the default memory requests for core services have been raised to 24GB, leaving only 8GB for an executor on a 32GB machine. This will be made configurable in an upcoming release in order to allow increasing execution resources again.

KNIME Business Hub 1.12.0

(released September 9, 2024)

Important installation notes

During the update executors of the Hub will restart. Some downtime in execution is expected.

Important changes (please read carefully)

  • The Secret Store feature is now also available for Business Hub Basic Edition licenses (See documentation)

Improvements

  • Scalability options for selected Hub services: IT now has the flexibility to configure resource usage and set limits for scaling with parameters such as minimum/maximum replicas, target CPU utilization, and memory resources for various Hub services like Account, Catalog, Execution Rest Interface, Search, and Websocket Proxy (See documentation)

  • New monitoring dashboards: Administrators now have access to metrics from Kubernetes, KNIME Business Hub services, and tools like Keycloak and Minio to understand KNIME Business Hub operations better and troubleshoot performance issues more effectively (See documentation)

  • Trigger deployments: Workflows can now be executed by events that occur across multiple teams and spaces, including those in newly created spaces. Global administrators can even set workflows to execute based on events across all spaces in the organization. This update is particularly helpful to administrators who want to deploy team or organization-wide governance workflows (See documentation)

Important Bugfixes

  • To avoid missing image problems coming up in airgapped installations. Garbage collection in the internal image registry shipped with Hub is now disabled by default.

Changelog (KNIME Business Hub 1.11)

KNIME Business Hub 1.11.2

(released August 21, 2024)

Important installation notes

  • Updates from the Business Hub 1.11.x version are highly recommended, as critical issues were fixed in this release.

Important Bugfixes

  • Fixed an issue in SCIM integration where percentage-encoding did not allow upper- and lowercase characters in SCIM endpoints

  • Fixed a bug where "number of executors" setting didn’t work for shared execution contexts through the Business Hub UI

  • Fixed an issue where refreshing a Box/Generic/Google OAuth2 Interactive secret via the Secret Store consume endpoint failed on the second refresh

  • Fixed an issue where Keyclaok didn’t start up properly in some cases after a restart

  • Fixed an issue in Secret Store where Google Sheets (read-only) scope group contained invalid scopes

Infrastructure update

  • Security update: KNIME Business Hub does no longer utilize role bindings to default service accounts

KNIME Business Hub 1.11.1

(released August 9, 2024)

Important installation notes

  • Updates from the Business Hub 1.11.0 version are highly recommended, as critical issues were fixed in this release.

  • Important If an external loadbalancer is deployed for handling TLS, and the coreDNS configuration update is disabled, the checkbox Istio Oudbound Traffic Redirect has to be disabled as well. Otherwise, internal calls to the hub URL will skip the Loadbalancer and TLS is not handled.

Important bugfix

  • Fixed the issue where in Business Hub 1.11.0 discarding and swapping jobs from running executors were not happening automatically. This would result in jobs piling up on the executor causing critical problems.

KNIME Business Hub 1.11.0

(released July 24, 2024)

Important installation notes

Important: If an external Loadbalancer is deployed for handling TLS, and the CoreDNS configuration update is disabled, the checkbox "Istio Outbound Traffic Redirect" has to be disabled as well on the KOTS Admin Console. Otherwise, internal calls to the Hub URL will skip the Loadbalancer and TLS is not handled.

Notice that due to the Postgres database update ~10 minutes downtime is expected.

Improvements

  • KNIME Business Hub now provides a GenAI Gateway that allows IT to centrally configure which GenAI providers and nodes can be accessed and used by team members

  • Workflows and components now come with rich descriptions

  • Personal credentials are now available to logged-in read-only users

  • Admins of KNIME Business Hub can assign memory limits to Teams

Infrastructure updates

  • Postgres database has been updated to version 16

  • Artemis has been updated to version 2.35.0

  • Quarkus has been updated to version 3.8 LTS

Important Bugfixes

  • Fixed an issue where deployment of Kots failed when there was no TLS certificate defined

  • Security context fixes

  • Various small bugfixes

Changelog (KNIME Business Hub 1.10)

KNIME Business Hub 1.10.2

(released July 9, 2024)

Important note: Updates from Business Hub 1.10.x versions are highly recommended, as critical issues were fixed in this release.

Important Bugfixes

  • Fixed an issue with memory allocation to Artemis (managing job queues for execution) that could cause failure of Business Hub.

  • Fixed an issue where jobs instrumentation (historical job collection) could fail because of late messages and cause failure of Business Hub.

KNIME Business Hub 1.10.1

(released June 4, 2024)

Improvements

Data App: Manage All Existing Jobs
Data App: Assign Users to Teams based on External Groups
Users sync from identity provider to Hub teams via SCIM is an Enterprise edition only feature.
Data App: Executor Image Builder

  • As the successor of the Execution Context Dockerfile Builder, the Executor Image Builder Data Application is designed to further ease the creation of Executor Images by employing the Image Builder Service that comes with KNIME Business Hub 1.10. This eliminates the need for manual docker image building on local machines, and instead allows easy installation of extensions or additional software like python to an Executor Image. The Executor Image is automatically pushed to a given registry (embedded, or configured in the Admin Portal) so that it is available for Global Admins and Team Admins so that they can create Execution Contexts from the Image. Detailed documentation can be found in the Docker executor images section of the KNIME Hub Admin Guide.

Other

  • Airgapped bundles now come with KNIME Analytics Platform 5.2.5 as executor.

Bugfixes

  • Fixed a bug where the job viewer feature doesn’t work on certain domains

  • Added license support for GCP marketplace images

  • Fixed a bug when sharing a secret with a team

  • Fixed a bug in Kerberos impersonation when connecting to an on-premise cluster

KNIME Business Hub 1.10.0

(released May 22, 2024)

Important changes (please read carefully)

  • The KOTS App Manager is now on version 1.108.9. This new version fixes an important CVE and provides new functionalities, so it has to be updated before updating to KNIME Business Hub version 1.10.

  • The Kurl update will result in a downtime of approximately 60 min. Please plan your update window accordingly.

  • Email addresses are now allowed as usernames. In case you had a Keycloak mapper configured that strips the domain portion of the username, this mapper can now be removed.

    • Caution: For the time being, do not remove the mapper if you are using Kerberos authentication in KNIME Analytics Platform. A fix for this will be provided in the next feature or bugfix release.

  • We changed the way groups in teams are managed. This change is only important for customers who added "guest members" to their teams to grant them access to individual spaces. If you are not doing this, please just skip the bullet point below.

    • Previously, it was possible for a user to be in a team without belonging to any of the team’s groups ("admin" and "member" by default). Now, a user is considered a part of a team as long as they are in any of the team’s groups. Therefore, having guest members by simply adding a user to a team, and then removing them from all groups is not possible anymore. To still achieve the same result, you need to add a new custom group to your team, to which the guest users are then added. Please reach out to support@knime.com to get assistance with this.

  • In case you are updating from Business Hub 1.8.x, Keycloak will be updated as well, resulting in a changed password to access the Keycloak admin portal. Please find the new password in a Kubernetes secret called credential-knime-keycloak in the knime namespace. If you have created additional Keycloak admins, they will be deleted as part of the update.

  • For customers using the external group sharing feature, the user-attribute mapper for external groups needs to be switched to userinfo-only. Please refer to the updated documentation.

  • Airgapped bundles now come with KNIME Analytics Platform 5.2.3 as executor.

Improvements

  • Group-to-team sync via SCIM (Enterprise edition only): Automatically sync groups from your identity provider to Business Hub teams. Changes on the identity provider side will reflect in Business Hub, making it easier for IT to onboard many users. (See documentation)

    • Note: In case you are using Kerberos authentication in KNIME Analytics Platform and if you are using a Keycloak mapper that strips the domain part from user names, do not set up SCIM yet. A fix for this will be provided in the next release.

  • Job instrumentation: This feature keeps a record of every single job that is executed on Business Hub, allowing users to analyze Hub usage over time. By default, records are kept for 30 days. This value can be adjusted in the KOTS admin console. (See documentation)

    • A data app to access this data is published here. Please upload this to your own Business Hub installation.

  • Job viewer: Users are able to inspect a job at its current state in a browser based read only mode, without the need to open their local KNIME Analytics Platform. This is possible for jobs that were created by an “Ad hoc execution” as well as from a “Deployment”. Usage of this features requires a KNIME Analytics Platform 5.2.3 or newer to be used as hub executor. (See documentation)

    • Note: In order to use the job viewer feature, load balancers / proxies in front of Business Hub need to be websocket compatible, and the ws.<baseurl> DNS entry needs to be set up as its shown on the KOTS admin console.

  • Scalable data app sharing: Share data apps at scale via a special link and run them without the need to log in for end users. (See documentation)

  • Secret store adds a new secret type for secure sharing of files e.g. ssh key files. (See documentation)

Security Updates

  • Minimal RBAC Kots install supported (See documentation)

  • Advanced installation now supports setting up Kots with limited RBAC permissions

  • PostgreSQL no longer requires privilege escalation to be enabled

  • fsGroups and supplementalGroups are now set for every container (exceptions are PostgreSQL, Istio and Ingress-Nginx)

  • Namespace-metadate-reader Cluster Role converted into a Role

Kurl update

  • Kurl stack updated

  • Contains various CVE fixes

  • Embedded clusters updated to Kubernetes version 1.27.12

Support bundle updates

  • Support bundles now indicate missing required resources in the Hub cluster

Important Bugfixes

  • Fixed a bug where application password creation for consumers was broken

  • Infrastructure fixes:

    • Excluding Istio from the install (for provided Istio / OpenShift Service Mesh) no longer requires a developer license

    • Fixed a bug where some init containers weren’t compatible with Istio CNI

    • Fixed a copy permission error in the Keycloak init container that caused issues with updates to Business Hub version 1.9.0

  • Backup / Restore fixes:

    • Postgres admin password wasn’t restored in some cases

    • Timeouts increased for large data volume backups / restores

  • Fixed a bug where Keycloak wasn’t compatible with custom certificate authorities

  • Fixed a bug where the ImagePullSecret was not set for Keycloak in some air gapped, embedded cluster installations

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.

Important Bugfixes

  • HUB-4774: Next execution time for schedules repeating every 24 hours cannot be computed

  • HUB-5093: Heap size calculation doesn’t work on Ubuntu 22.04 (Cgroups V2), leading to a too low limit being set for various services

Changelog (KNIME Business Hub 1.3.0)

KNIME Business Hub 1.3.0

(released April 03, 2023)

Important installation notes

  • With the release of KNIME Business Hub 1.3.0 new security features are introduced regarding executor communication. For this reason, KNIME Business Hub requires every executor to be on Analytics Platform version 4.7.1 or higher. You can find a list of the available executor images here.

  • With this release we changed the istio configuration of two services, to allow them to see the IP of the caller if the request is coming from within the cluster. This can cause those two services (keycloak-proxy, s3-proxy) to not start up in some scenarios, with a "too many open files" error in the istio-proxy container of those pods. This can be fixed by increasing the open file limit on the host VM, e.g. by running the following command:
    sudo sysctl fs.inotify.max_user_instances=8192.

  • The KOTS App Manager is now on version 1.96.3. This new version fixes an important bug, so it should be updated before updating to KNIME Business Hub version 1. 3. To do so use the following command:
    curl -sSL https://kurl.sh/knime-hub | sudo bash.

  • If you haven’t updated to KNIME Business Hub 1.2.0, yet, you need to follow update guide in the changelog for 1.2.0 before updating to 1.3.

New Features

Molecule sketcher
Use the new Molecule Widget (Labs) node to accept molecule input from your users. With this new node we made the integration of different sketchers easier and allowed to provide different sketchers also for the KNIME Analytics Platform. In this release the ketcher sketcher is included. Additional sketchers will follow in the upcoming releases.

Collections
Introduce your users to a topic using collection pages. Collection pages serve as a starting point for your users to explore examples and building blocks related to your chosen topic, facilitating their onboarding process. To start creating collections read our guide here.

KNIME Analytics Platform customization profiles
Use Business Hub to distribute preference profiles to either local Analytics Platform clients or to KNIME Hub executors. This can be used to e.g. easily ship database drivers. More information about Analytics Platform customization profiles here.

Trigger deployment
Trigger is a powerful new type of deployment which allows automating workflow execution based on specific conditions, such as another workflow or component being added or removed to a space. To get started with Triggers, check out our documentation here.
