The flow builder includes an integrated AI chat panel that lets you create and modify flows using natural language. Just describe what you want to achieve, and the AI will build the flow for you, step by step.

The inline script editor in the flow editor now also includes a diff toggle to quickly check the diff between the changes made and the deployed version.

Capture triggers inputs from test mode.

Approve or reject flow steps directly from Slack with support for form inputs.

Introducing the Quick Access Menu—a streamlined solution that centralizes all key features previously scattered across side panels. Now, you can benefit from the full potential of search, enhanced by intuitive filters, all in one place.

You can now edit directly the YAML of flows within the flow editor.

On approval steps, a new toggle to continue flow execution on disapproval of approval step. If set, instead of failing the flow will bubble up the error and continue.

Scripts and flows can now be triggered by the delivery of an email.

Windmill now pre-bundles TypeScript (Bun) scripts using Bun bundler and caches them on S3 and locally at deployment time. Furthermore, if a Bun script is run while not being pre-bundled, it will be re-bundled. This will increase stability and optimize (in some cases with 60% improvement) the execution time and the memory consumption, in particular for scripts with many/heavy imports and relative imports.

We also did improvements for non-deployed scripts using better caching strategies for the dependency cache. You cannot do any faster than running a pre-bundled script aside from having the script being already running which is what dedicated workers are made for. This makes Windmill the fastest platform to run TypeScript.

However, in very rare cases (< 1%), this might break existing bun scripts that are incompatible with being bundled. If you notice such issue for a particular script after the upgrade, add //nobundling to the top of the script.

Improved the flow status viewer readability.

Flows now have versions just like scripts and apps.

Added new type of input `oneOf@, that displays an option between multiple objects.

Windmill now automatically tracks relative imports in Bun and Python such that if you update a common dependency and update its imports, it will now re-trigger deployment and lockfile computation of all the scripts that depend on it (it was working for Python but not Bun before).

Windmill can now also track such imports in inline scripts of flows and will surgically update the inline lockfiles of those flows if the relative imports change.

Obversability around concurrent jobs has been improved from the Runs menu.

Labels allow to add static or dynamic tags to jobs with property "wm_labels" followed by an array of strings (e.g. return {"wm_labels":["showcase_labels", "another_label"]}

When enabled, the flow will continue to the next step after going through all the retries (if any) even if this step fails.

While loops execute a sequence of code indefinitely until the user cancels or a step set to Early stop stops.

Improved the experience with approval steps.

Map support in Rich display rendering.

We now support GH flavored markdown for description of scripts, flows, resources.

You can set and retrieve a value given a key from any step of flow and it will be available from within the flow globally.

Flows are not the only way to write distributed programs that execute distinct jobs. Another approach is to write a program that defines the jobs and their dependencies, and then execute that program. This is known as workflows as code.

The Flow & metadata copilot is an assistant powered by an OpenAI resource that simplifies your script & flows building experience by population fields (summaries, descriptions, step input expressions) automatically based on context and prompts.

Added rich results render for arrays of objects and markdown in scripts and flows.
