v26.3.0-rc.2

✨ Features

Service Launcher UX Improvement

When autoscaling rules are active on an endpoint, the replica count input is now automatically disabled with a tooltip and informational alert explaining why. This prevents conflicting configurations between manual replica settings and autoscaling policies.

• FR-2232: disable replica count input when autoscaling rules are active by @yomybaby in #5886

Developer Experience

Integrated react-grab as a development-only tool, enabling AI coding agents to inspect UI elements by hovering and copying component context (file path, component name, line number) via ⌘C. This is excluded from production builds.

• FR-2218: integrate react-grab for AI agent element inspection by @yomybaby in #5887

🐛 Bug Fixes

Endpoint Routing Compatibility

Fixed an issue where legacy routings field was fetched unnecessarily on servers that support the newer route-node feature. The query now skips routings when route-node is supported, using route_nodes instead. Also removes the legacy RoutingsCount column from the endpoint list view.

• FR-2261: skip routings when route-node is supported by @nowgnuesLee in #5905

🛠 Chores

CI Pipeline Fix

Fixed a post-install cache error in the release CI workflow caused by a conflicting manual pnpm store path configuration. The fix delegates store path detection and caching entirely to actions/setup-node.

• fix: remove redundant pnpm store config causing post-install cache error by @yomybaby in #5879
