The week in marketing-automation

Agent infrastructure is where the activity is. Gumloop gave agent-built artifacts access to AI models, embedding and device inputs, and n8n fixed its agent runtime, OAuth sessions and sub-workflow redaction. Both are products that automate workflows, and both spent the week on what agents can reach and what they can see.

Security patching ran alongside. Pimcore closed two more advisories in 2026.3.3, and n8n fixed redaction so parent executions hide data from viewers who can't use a sub-workflow's credentials.

Leaders

Gumloop ships a numbered release every few days. 12.5 lets dashboards and apps that agents build call AI models, embed on any site and use the mic, camera and clipboard, adds a Slack channel-join trigger and makes browser sign-ins and embedded forms more reliable. 12.4 added agent-built custom MCPs, multi-account apps and cross-team sharing, and 12.0 gave agents a real browser.

n8n 2.45.0, published October 20, is a minor release whose visible notes are a long list of fixes: agents accept gateway model IDs and forward credential headers, each OAuth request gets its own session, and idle mcp-browser sessions are evicted. Its 2.43.7 patch suspends in-flight executions at worker shutdown.

Pimcore 2026.3.3 patches a Custom Reports SQL denylist bypass and object injection via the session tmp_store, and lightens ManyToMany loading. It follows 2026.3.2, which fixed an IDOR, a Twig sandbox bypass and object injection.

Wildcards

Buttondown posts a changelog entry nearly every day. This week brought two iPhone editor keyboard fixes, filters that accept date-named metadata keys, fully translated archives and, on October 21, screen-reader support with a skip-to-content link, page-change announcements and labels for icon-only buttons.

Moosend has no product release: every entry in its feed over two months is a blog post, most recently on SEO-friendly content.

Themes that compounded

  • Agent runtimes were extended in Gumloop and fixed in n8n.
  • MCP support deepened in Gumloop (agent-built MCPs) and n8n (idle mcp-browser eviction).
  • Security advisories were patched in Pimcore, and redaction was corrected in n8n.
  • Accessibility work appeared in Buttondown.

Watch this week

Gumloop has gone from 12.0 to 12.5 on a cadence of days, so another numbered release is likely. n8n patches two supported lines almost daily and 2.45.0 is new, so expect early fixes. Pimcore ships on a weekly patch train, which puts 2026.3.4 next in line.
