n8n releases version 2.45.4 with bug fixes and editor features
n8n published release 2.45.4 on 2026-10-26 on its GitHub repository. The release lists bug fixes across core, editor, the IMAP Email Trigger node, the Microsoft SharePoint node, and the task runner's certifi dependency, plus editor features including a migration report filter by project.
Why it matters
Builders running self-hosted or cloud n8n workflows get fixes for IMAP trigger reconnect behavior, SharePoint column mapping (403 errors and empty items), and sub-workflow error handling when pre-run checks fail. Teams relying on these nodes may see changed behavior after upgrading.
Who should care
n8n users and self-hosters, automation builders using IMAP or SharePoint nodes, agencies maintaining client workflows
What you can do
Review the 2.45.4 release notes against your workflows that use the IMAP Email Trigger or Microsoft SharePoint nodes, then test them on a staging instance before upgrading production.
