We are happy to announce that KNIME Analytics Platform 5.5 is now available to download.
This release makes agent development more accessible for anyone who wants to build them, without the need to deal with complex integrations, coding, or steep learning curves. You also get expanded AI model options with new connectors for Anthropic Claude and Googleās Gemini models.
Here are the releaseās highlights:
Build agents more easily than ever using powerful new capabilities, including the Agent Prompter node, which encapsulates tool extraction, selection, and iteration in a single node. Add a readymade chat interface to your agentic data apps with the Agent Chat View node and easily build new workflows as tools or turn existing workflows into tools using KNIME concepts youāre familiar with. Get the details here.
Use Anthropic Claude, Gemini models from Google AI Studio and Vertex AI, and models from IBM watsonx.ai with new connector nodes.
K-AI is now redesigned as an agentic system, working alongside you as an AI colleague. It uses nodes as tools, greatly expanding the possibilities of your workflow development.
Version your workflows uploaded to KNIME Hub directly within KNIME Analytics Platform without the need to switch interfaces.
Access component dialogs in the side panel, see components output directly in the bottom panel, and reorder tabs and align nodes for better workflow organization.
A completely rebuilt workflow canvas rendering system makes large workflows load faster and respond better (available as an experimental feature in preferences). Try it out and share your feedback.
Work directly with date and time data types in Expression nodes for simpler operations, plus modernized Date & Time nodes for improved usability.
Connect with major services in Microsoft Fabric, read and write data within Microsoft Fabric OneLake and Data Warehouse, and manage Power BI semantic models.

With KNIME 5.5, is it no longer possible to run multiple KNIME processes, e.g. run three at the same time scheduled using Task Scheduler while opening a KNIME interactive window directly, creating a new workflow.
I see that my tasks that run a the same time have been failing when at least one KNIME 5.5 process is already running.
Itās happening on a Windows Server 2016. Iām only using the free KNIME AP.
I recently tried to upgrade to the 5.5 version of KNIME and now I can no longer open KNIME. The KNIME loading screen pops-up, but this is quickly followed by a blank white screen. I tried restarting my computer and that classic quick fix didnāt help this time.
Have there been any reported issues with upgrading to 5.5? I would directly download 5.5, but for my work lap top they restrict our download to 5.1.2. However, I had previously upgraded all the way to 5.4.4 it was just this last upgrade that didnāt seem to go well. Any thoughts or suggestions?
We have significant amount of on-prem resources due to past investment decisions. I have been running the free KNIME AP on a Windows Server 2016.
Most of the KNIME processes are scheduled in Microsoft Task Scheduler using the technique described at FAQ | KNIME
I have .bat files containing those suggested command prompt lines set up as Microsoft Task Scheduler Actions. Multiple KNIME tasks in there may run at the same time.
In addition to running background Task Scheduler KNIME tasks simultaneously. I also sometimes open KNIME AP interactively to edit a workflow or to troubleshoot problems with the background tasks. This has been working just fine up to KNIME 5.4.4.
Starting in KNIME 5.5. If there is a KNIME task running in the background, when I open KNIME AP interactively, I will see the splash screen and the workspace selection window, but after selecting a workspace, KNIME would never open. I also saw failed tasks related to those background KNIME tasks that run simultaneously.
After downgrading to KNIME 5.4.4, the tasks have been running just fine.
Please let me know if you need more info from me. Iām sorry for freeloading your software, but Iām trying to make up for it by advocating for KNIME in Reddit.
Thanks, I tried it and it worked for me. I hope they fix it with the patch because it happens to me very often. It all happened after installing version 5.5.
We do offer scheduled workflow execution on KNIME Community Hub now, perhaps thatās something your employer could look into . The old Batch Execution mode is not being developed any more and may be decommissioned at some point in the future.
Interesting! KNIME (and Eclipse) workspaces are not meant to be used from multiple applications simultaneously, and at least the desktop application does check for that and doesnāt allow you to open two instances with the same workspace. It looks like the Batch Executor application is missing that check, which made your usage pattern possible until now.
The new version of the integrated web browser (CEF) shipped with AP 5.5.0 now relies on the assumption that it has exclusive access to the workspace and crashes during start-up if it doesnāt. While this clearly breaks some (exotic?) use cases, Iād be hesitant to call it a clear bug in CEF. You could also argue that the Batch Executor is buggy because it doesnāt lock its workspace properly. A fix there would also break your setup. Iāll discuss the problem internally and open a ticket.
If you want to continue to run multiple Batch Executor processes in parallel in 5.5.0, youāll have to assign them to separate workspaces. You can do this using the -data <WorkspaceDir> commandline parameter. Youāll need to write the creation and cleanup logic yourself, but at least it will work. Debugging etc. will obviously be less convenient.
Hi team,
thanks for sharing the update with us.
Unfortunately I have to confirm to better run a version behind the announced one as to ensure the errors are gone before using it live.
Unfortunately for me I encountered a very sad situation.
I started my current 5.4.4 and upgraded app internal.
First the app updated and after reboot the AddIns were updated too.
Upon the app restart and/or a full laptop restart KNIME starts but is completely empty.
Just a white space. No canvas, no menu etc. just the menu in the top left to close the app.
And unfortunately I lost all tabs with my āopenā workflows.
Iāll guess I have to go for another fresh install.
Would someone be able to offer a direct link to the executable rather to go through the registration process again and again?
Regarding the āblank screen issueā, please follow up in the new topic that was created above.
(Short update: we were able to reproduce the issue on one system, but we still havenāt gotten to the bottom of the problem. Using -clean, as suggested above by @rrousselot), seems to help.)
