Changelog

All notable changes to Knots Flow will be documented in this file.

Unreleased

1.13.0 - 22.09.2026

Changed

  • FEEL playground now prepopulates its input with the values of the selected execution, falling back to placeholders for nodes that did not run

Fixed

  • Dragging a gateway condition to reorder it now also reorders its underlying edge, so the new order is actually respected when the flow runs
  • Editing large workflows no longer lags: typing in a node, panning the canvas and copy/pasting stay responsive on flows with over 100 nodes, and such flows also open faster

1.12.0 - 15.09.2026

Added

  • Warning notification when the session is about to expire, so work can be saved before being logged out
  • The AI assistant can now build a workflow from the dashboard: it creates the workflow and opens it in the editor
  • Conversation starter suggestions in the AI assistant sidebar, shown under the chat input on the workflow editor page
  • The AI assistant can now read the workflow you currently have open, including unsaved changes, so it can answer questions about it and edit it in place instead of rebuilding it from scratch

Changed

  • FEEL playground now prepopulates its input with the values of the selected execution, falling back to placeholders for nodes that did not run

1.11.0 - 26.08.2026

Added

  • Flow history text editor now recognizes Liquid filter expressions ({{ x | filter }}) and {% tag %} blocks (including {% if %}...{% endif %}-style blocks and {% raw %}...{% endraw %}) as editable "Liquid expression" pills, distinct from plain variable-reference pills.
  • Clicking a Liquid expression pill opens a modal to edit its raw text, with syntax validated against liquidjs before saving.
  • Drag-and-drop reordering of gateway conditions
  • Warning when deactivating a module that is used in flows

Fixed
