2026 H1 Release Recap ♥︎

As we hit the midpoint of 2026, we wanted to take a moment to share our first-half Release Recap, highlighting the most impactful improvements delivered for you across Q1 and Q2, in case you missed any in the day-to-day.

The first half of 2026 has been about making Atomic smarter, more connected, and easier to operate at scale. We expanded our integration ecosystem, introduced AI into the Workbench, and shipped a series of improvements to help teams build, debug, and manage Action Flows with less friction. Here's our top eight:

1. Ask Atomic: AI-powered Workbench assistant Ask Atomic launched in beta in March, bringing an AI assistant directly into the Workbench. Designed to help you understand and use Atomic more effectively, Ask Atomic can answer questions about features, configuration, and best practices without leaving your workflow.

2. Action Flow Runs tab for real-time debugging The new Runs tab in the Action Flow editor lets you inspect specific Action Flow instances as they execute. You can view the status of each step, preview cards and notifications, see resolved variable values, and review analytic events, all in real time. This makes it significantly easier to understand what happened (and why) for any given flow run. Currently in preview for selected organisations.

3. Fine-grained API keys with expiry and IP restrictions A major upgrade to API key management landed in April. You can now create API keys scoped to specific API operations, set expiration dates, and restrict usage to allowed IP addresses or CIDR ranges. Organisations can also enforce a maximum key lifetime and block creation of new legacy keys. This gives security and compliance teams much tighter control over API access.

4. Pre-configured integration steps for Slack, WhatsApp, Notion, Google Sheets and Customer.io Throughout Q1 and Q2 we added a growing library of pre-configured Action Flow steps for popular services. You can now send messages to Slack, send text and image messages via WhatsApp, read and write to Google Sheets, create pages in Notion, and trigger workflows in Customer.io, all without writing custom request configuration from scratch.

5. Action Flow folder navigation with drag-and-drop Managing a growing library of Action Flows got a lot easier with the new column-style folder browser. You can navigate with your keyboard, drag and drop flows between folders, and nest folders up to three levels deep. Alongside this, the Action Flows page now shows lightweight engagement metrics at the top of the page, so you can see at a glance what's active and what's not.

6. Test send-request steps without running the full flow A small but high-impact addition: you can now test individual send-request steps directly from the Action Flow editor using the "Test request" button. No need to trigger the entire flow just to validate an integration is configured correctly. This alone can save significant time when building and troubleshooting flows.

7. mTLS support for enterprise integrations Mutual TLS (mTLS) is now available in preview, allowing send-request steps and webhook subscriptions to use client certificates. For organisations with strict security requirements around service-to-service communication, this removes a common blocker to integrating Atomic into existing infrastructure.

8. iOS interruption levels and Android channel customisation for push notifications You can now set the iOS interruption level (time-sensitive, critical) for individual push notification steps or card push notifications, and customise the Android notification channel per notification. This gives you finer control over how notifications are surfaced on each platform, helping you balance urgency with user experience.

Alongside these headline improvements, the first half of 2026 also delivered a new insights permission model, stream container platform and SDK version visibility, Google service account credential uploads, icon alt text for accessibility, Action Flow step search, bulk media uploads, and dozens of smaller fixes and refinements across the Workbench, SDKs, and platform.

What's coming next

We're not slowing down. Here's a taste of what the team is working on for the second half of 2026.

SDK 26.2.0 is right around the corner, bringing a series of card layout improvements including new category element features with additional icon theming and sub-headings, text alignment options (center, right, left), expanded text block styles (primary, secondary, tertiary), and heading levels (h1, h2, h3). These add up to significantly more control over how your cards look and feel.

On the platform side, we're exploring some exciting new capabilities. We're bringing MCP (Model Context Protocol) support into Atomic, adding AI-powered steps directly into Action Flows, and reworking the theme editor to make it easier to manage your design system. These are still taking shape, but we're excited about where they're headed.

If any of this sounds interesting, or if you'd like early access as these features roll out, we'd love to hear from you. Get in touch and let's chat about what's ahead.
