# Elevating security, control, and accessibility: Stack Internal 2026.6

**Type:** Announcement

## Summary

Stack Internal 2026.6 is a release focused on administrative security, API control, developer portal integration, knowledge-health automation, and accessibility for enterprise AI workflows. Its new Admin Security page supports X-API-Key headers for API v2.3 requests, inactivity windows, per-application daily limits up to 10,000 requests per day, and service-credential rotation with non-displayable secrets. The release adds scheduled expiration for Announcement articles, generally available community broadcasts, expanded custom award limits, tag preference and synonym APIs, richer user data, and a Backstage plugin update supporting the New Frontend System alongside the legacy architecture. Accessibility work improves screen-reader announcements, keyboard and reflow navigation, focus management, high-zoom layouts, contrast, and semantic markup, while additional fixes address tags, suggested edits, and Slack rendering.

## Context

Enterprise teams are expanding API access for internal AI tooling and automated workflows, creating a need for stronger pipeline governance. The release also addresses stale knowledge that can cause agent mistakes and human confusion, and the need for decision-grade knowledge to remain accessible across user, moderator, and administrator workflows.

## Approach / What changed

The release adds a unified Admin Security page, API controls, automated article expiration, community broadcasts, expanded award limits, tag and user-context APIs, Backstage integration updates, and accessibility improvements covering screen readers, keyboard navigation, reflow, focus management, contrast, and semantic markup.

## Takeaways

- API v2.3 requests can require X-API-Key headers, while administrators can set inactivity windows, customize application-level daily limits up to 10,000 requests, and rotate non-displayable service credentials.
- Announcement articles can receive scheduled expiration dates and are automatically soft-deleted when they expire; Community Broadcasts are now generally available for prominent notices and “For You” notifications.
- The Backstage plugin from v1.7.0 supports the New Frontend System as well as the legacy architecture, and accessibility changes improve screen-reader feedback, keyboard navigation, reflow, contrast, and semantic markup.
