This log gives an overview of the most prominent changes in each release. Minor fixes, changes “under the hood” and refactoring changes are not listed here. We follow the Semantic Versioning scheme and the guidelines from “Keep a Changelog” as close as possible.
version-1.22.0 (2025-05-08)
Change
Make NodePit Runner's web interface responsive. The UI can now be seamlessly used on smaller displays such as mobile phones and tablets.
Greatly improve the performance of the NodePit Runner API and the web interface. Requests are now up to 10x faster.
version-1.21.0 (2025-04-26)
Change
Improve impersonation feature; impersonation will now always start in a new tab and be focused to this tab; you can now impersonate different users simultaneously. Closing the tab will end impersonation.
Change
Add more buttons on detail and edit views - e.g. you can copy, delete, or run a schedule without having to go back to the list view.
Change
Show loading indicator on login screen.
Change
Increase automated run cleanup interval from 15 minutes to 1 minute, making the manual “Cleanup Runs” button obsolete.
Remove
Remove “Cleanup Executors” button and corresponding API route POST /executor/cleanup.
Remove
Remove “Cleanup Runs” button and corresponding API route POST /run/cleanup.
version-1.20.0 (2025-03-19)
Add
Add KNIME version suggestions in KNIME environments. As you type, NodePit Runner now suggests valid KNIME versions, including additional meta information, for easy selection.
Add
Add support for KNIME Nightly builds. KNIME Nightly builds include the latest development changes and are not recommended for production. Due to continuous updates, environments using KNIME Nightly are not cached and will be rebuilt from scratch on every run.
Add
Add file preview capabilities for KNIME workflows. You can now see a preview of your workflow by clicking on a workflow file in the file list.
Change
Set KNIME 5.4.3 as the default for new environments.
Fix
Fix an issue that caused the update banner to always show up in NodePit Runner Nightly, as the latest release version was always considered newer than the nightly version.
Fix
Don't fail showing the Settings page when the latest NodePit Runner release version could not be fetched.
version-1.19.0 (2025-02-18)
Change
Set KNIME 5.4.2 as the default for new environments.
Change
Set JVM arguments for KNIME environments automatically based on the selected KNIME version
Fix
Fix an issue that sporadically caused workflows using REST nodes to hang.
Fix
Add required validation for KNIME version input.
version-1.18.0 (2025-01-19)
Add
Collect and view run metrics in the Run View. Statistics such as CPU and memory usage, as well as network and disk traffic, can now be viewed during and after the execution of your workflow or script. This gives you great insight into what your run is doing and helps you debug resource-related errors.
Change
Scripts with a sh extension added via additional files are now executable by default. This enables configuring Python using Anaconda with a start script according to the KNIME Python Integration Guide. However, we still recommend using the bundled Python or configuring it manually as described in our FAQ.
Change
When errors occur in KNIME-based environments, log files from the underlying Eclipse are now added to the executor's logs. This may provide more information on why a run failed in certain cases.
Change
Use term Extension Search consistently throughout the documentation (previously named Plugin Search).
Fix
Fix an issue that caused additional files defined on the schedule level for shell schedules to be ignored and thus not being available during execution.
Fix
Fix an issue that caused an exception when adding extensions via the “Extension Search” to a freshly created KNIME environment.
version-1.17.1 (2025-01-04)
Fix
Fix license check for edge cases. Previously the license check could give a negative result for the last day of the license period.
Fix
Fix an issue that caused failed runs when installing certain Python packages via “Additional Dockerfile Instructions”.
version-1.17.0 (2024-12-07)
Add
Add support for KNIME 5.4.0. Please make sure to update NodePit Runner when using KNIME 5.4.
Change
Executors are now identified by their container name. As a result, you can now update your executors or scale them up or down (with docker compose scale executor=2) without getting completely new executor entries in the executor list.
Change
Set KNIME 5.4.0 as the default for new environments.
Remove
Remove the SHARED_VOLUME_NAME environment variable for executors. Executors don't need to explicitly configure the shared volume, as this is now derived programmatically. You still need to mount a data volume into the executor container with target /opt/data (as already done previously).
version-1.16.0 (2024-11-26)
Add
Executors can now be paused. Paused executors still finish any assigned runs, but will not execute new runs. This can be useful if you want to temporarily stop an executor from running schedules, but don't want to remove or unregister it.
Add
Executors can now be modified by admins via UI (e.g. change the executor's description or modify tags).
Add
Show run count for each executor.
Add
Show run list per executor.
Change
You can now set environment variables INITIAL_DESCRIPTION and INITIAL_TAGS for executor containers. These values will only be honored when the executor registers against the NodePit Runner API. Changing descriptions and tags afterwards can now be done via the UI.
Deprecate
The environment variables DESCRIPTION and TAGS for executor containers are now deprecated and are currently mapped to INITIAL_DESCRIPTION and INITIAL_TAGS.
version-1.15.0 (2024-11-20)
Add
Add tags to executors, environments, and schedules to control where runs are executed. You can now assign tags to executors via the TAGS environment variable (e.g. TAGS=large,gpu). Runs of environments and schedules that require a certain tag (e.g. large) can now only be executed by executors that are tagged accordingly. Runs without tags can also be executed by executors with tags.
Add
Add new configuration option “Cancel Pending Runs After” that automatically cancels long pending runs (e.g. due to missing executors).
Add
Add search functionality for the log output of a run.
Add
Add an option to copy the entire log output to the clipboard. This eliminates the need to manually select particularly long logs.
Add
Add an option to download the entire log as file.
Add
Add highlighting of log lines and the ability to create links to highlighted lines. Select individual log lines by clicking on the line number. Hold down the Shift key and click on the line numbers to select a group of lines. Copy the URL which will now also contain information about the selected lines.
Add
Add timeout configuration. Global timeouts can now be set by administrators in the Settings menu. No timeout is configured by default.
Add
Add timeout configuration for schedules. Schedules can now define their own timeout, which overrides any global timeout that may exist. By default, schedules respect the global timeout.
Add
Add search input field to runs.
Add
Add sorting to overview tables for executors, users, environments, files, and schedules.
Change
Set KNIME 5.3.3 as the default for new environments.
Change
Don't show unconfirmed users as suggestions for project members.
Change
All confirmed users now have read-only access to non-sensitive information in the “Executor” tab. This allows users to gain more insight into the available executors and understand why runs may not be starting.
Change
Show more information about runs on overview and details pages (e.g. duration, queue time, assigned executor).
Remove
Remove obsolete configuration options EXECUTOR_INACTIVE_TIMEOUT and EXECUTOR_ORPHANED_RUN_TIMEOUT. Previously, executers reported their status less frequently and less reliably, requiring timeouts configurable via environment variables. Recent fixes have removed the need to set these variables to increase our configured defaults.
Remove
Remove the RUN_TIMEOUT configuration option in favour of a configuration via the Settings menu.
Fix
During a run only scroll to the end of the log section when new log lines are available. Previously every five seconds the run view page had been scrolled to the bottom for active runs.
Fix
Canceling runs is now much faster as operations such as pulling, building or pushing worker images can now be aborted and don't need to be finished.
version-1.14.0 (2024-10-17)
Add
Add project role Maintainer. Maintainers have read and write access to a project's items, but are prohibited from changing the project configuration (e.g. rename project, delete project, add or remove members).
Add
Add project role Operator. Operators can read project items, but don't have permission to modify them. Operators can trigger runs to execute already pre-configured workflows and scripts. Operators can also abort and delete runs they have started.
Add
Add link to this changelog to settings page for easy access.
Change
Add the project name of the schedule to email notifications. This makes it easier to identify which schedule the notification belongs to, especially if you have multiple schedules with the same name in different projects.
Change
Run archives now contain knwf and knar files of executed workflows, which can be easily opened in KNIME by double-clicking. The previously stored unexecuted workflow is no longer part of the archive, but can be downloaded from the File menu.
Change
Show if a run has been triggered manually or by schedule on run details page.
Change
Show the name of the user that has manually triggered a run on run details page.
Fix
Fix an issue that let to new users beeing auto-confirmed.

Add
Allow admins to easily clean up all inactive and unused executors on executor overview.
Change
Set KNIME 5.2.5 as the default for new environments.
Change
Allow the environment cache to be cleared on the “Edit Environment” page. Clearing the environment cache forces the environment to be rebuilt the next time it is run, and can be used to force the installation of new versions of plugins and extensions that would otherwise have been cached.
Change
Apply additional validity checks and improve error messages for enhanced robustness of NodePit Runner API.
Change
Implement request-based retry functionality in the Executor component to compensate for short-term network outages.
Change
Consolidate API endpoints and flatten the structure of resources returned via the API. Depending on if and how you use the NodePit Runner API, please update to the latest version of NodePit Runner Nodes and/or check the updated API specification.
Change
Remove existing file upload limitations. Previously only a limited list of file extensions were allowed (e.g. knwf, sh, epf). With support for additionalFiles in environments and schedules, user are now able to upload any kind of file.
Fix
Fix an issue that caused a large number of runs to be created when the schedule fell into the daylight saving time switchover.
Fix
Fix a problem that caused inconsistent data when changing the type of an existing and already used environment. In future, it will no longer be possible to change the type of an environment.

Formatting of license information in UI.
version-1.10.0 (2024-02-22)
Add
Add “Projects” to NodePit Runner. Projects are a new way to group and isolate environments, schedules, files and runs (e.g. by department, business unit, topic) and make them available to other users. Invite users to your project and assign them a role to determine their access right (e.g. owner for read and write access and reader for read-only access).
