TypeScript SDK (qstash-js):
Added support for the Anthropics provider and refactored the api field of publishJSON. See the documentation here. Full changelog, including fixes, is available here.
Qstash Server:
Fixed a bug in schedule reporting. The Upstash-Caller-IP header now correctly reports the user’s IP address instead of an internal IP for schedules. Validated the scheduleId parameter. The scheduleId must now be alphanumeric or include hyphens, underscores, or periods. Added filtering support to bulk message cancellation. Users can now delete messages matching specific filters. See Rest API here. Resolved a bug that caused the DLQ Console to become unusable when data was too large. Fixed an issue with queues that caused them to stop during temporary network communication problems with the storage layer.
