Release v20.66.1

Summary

An observable query whose backend returns a primitive collection — for example ISubject<IEnumerable<string>> — delivered a collection of empty values to the client instead of the actual data. Names rendered blank, comparisons failed, and string interpolation produced an empty string. One-shot queries were unaffected, so this only surfaced on live/observable queries.

Fixed

• Observable queries returning a collection of primitives (string, numeric, bool) now deliver the actual values instead of empty ones, both for the initial payload and for change-set deltas
• Observable queries returning a single primitive value now deliver that value instead of an empty one
• Observable queries that describe themselves with Object now pass their payload through instead of losing it
