n8n has shipped version 2.36.3, a patch release that brings several under-the-hood fixes to improve stability and efficiency for self-hosted deployments. The update mainly targets core internals and the workflow editor.
On the core side, the release prevents task runners from being restarted when they are simply slow, avoiding unnecessary disruptions in long-running workflows. It also delays initialization of the expression engine until a command actually needs to evaluate expressions, saving memory and startup time for other operations. Finally, test webhooks now wait for teardown to complete before releasing their isolate, eliminating a potential race condition that could cause flaky tests.
For the editor, the type selector in the Edit Fields modal has been visually restored, fixing a regression that affected the styling of that component and ensuring a more polished user experience when mapping data fields.
