This patch release fixes critical issues with payload truncation and caching to ensure proper pagination support in read_cache operations.
Bug Fixes
-
Fixed cache key collisions in truncated payloads - Resolved an issue where truncated payloads could share cache keys, causing data corruption. Each truncated payload now generates a unique cache key based on its specific content and truncation parameters.
-
Fixed read_cache pagination for truncated content - Truncated payloads are now persisted and recursively cached, enabling proper pagination through large truncated responses. This ensures that clients can reliably retrieve all pages of truncated data using read_cache.
-
Improved truncation observability - Added enhanced logging and monitoring for read_cache truncation operations, making it easier to diagnose issues with cached truncated payloads.
These fixes apply to both Personal and Teams editions.
