Regular release update May 7th, 2026

Features:

Data resource errors now include an optional statusCode property that contains the HTTP status code from the failed fetch (UNI-9158)

// Filter for errors that have status codes const fetchErrors = issues.filter( (i): i is DataResourceIssue => i.type === "data" && typeof i.statusCode === "number" ); // Filter for specific status codes (e.g., rate limits) const rateLimitErrors = fetchErrors.filter(i => i.statusCode === 429);

This addresses the need to handle errors beyond simple message filtering, particularly for rate limits (429) and other HTTP status codes.

Custom edgehancers can now report HTTP status codes when registering errors via the mesh-edgehancer-sdk:

// Custom edgehancers can include statusCode in error objects return { errors: [ { message: "Failed to fetch data", statusCode: 404 } ] };

The statusCode field is automatically validated and passed through to the final error response.

Replaced ariakit with base-ui component library within the uniform design system (the replacement is backwards-compatible)

Improvements:

Improved validation clarity of the locale definitions management screen (UNI-9265)

Bug fixes:

Pattern-derived components now properly show Personalize This and A/B Test This options in the composition editor preview highlighter, and variant menu items display both the variant name and component title for better clarity. (UNI-5842)
Fixed the "Open a different composition" button being cut off in the header when the Scout sidebar is pinned. (UNI-9268)
Slot's allowedComponents list now allows IDs of up to 100 characters, matching the maximum length allowed for component public IDs (UNI-6697)
