Notes for all versions
Updating CRDs
Some upgrades include changes to Custom Resource Definitions (CRDs).
If you are using the automated CRD updater tool bundled with the KNIME Business Hub application, CRDs are updated automatically during the upgrade.
If you have disabled the updater and installed CRDs manually, make sure to re-apply the latest CRDs from the public repository after each upgrade.
Outdated CRDs can cause issues such as executor errors or failed component deployments.
KNIME Business Hub version 1.16
Important notice for existing customers (32 GiB RAM instances)
Previously, a Hub instance with 32 GiB of RAM could host executors configured with up to 12 GiB of memory. After this update, the maximum executor size must be reduced to 8 GiB before starting the upgrade (Editing Executor Configuration). If executor memory is not adjusted, executors will fail to start until their configuration is lowered.
For customers on instances with more than 32 GiB RAM
In some cases, a large share of memory may already be reserved for execution. To ensure smooth operation, core services now require 24 GiB, leaving the remainder available for execution. Please adjust your executor memory accordingly before the update.
Updated RoleBinding
for license validation
With this release the RoleBinding
used for license validation has been updated with additional ServiceAccount
references. If you’ve installed KNIME Business Hub with Minimal RBAC you need to apply the updated Cluster Roles as described here before updating.
