Upstash

Upstash Redis Search shipped in March — a full-text search extension that auto-syncs indexes with Redis writes.¹ It works with JSON, Hash, and String data, supports full-text queries, filtering, aggregations, fuzzy matching, phrase queries, and regex. Adapters for node-redis and ioredis (@upstash/search-redis, @upstash/search-ioredis) let existing clients adopt it without switching SDKs.

QStash flow control got a ground-up rewrite. The cancellation model changed from scheduling messages to future timestamps (holding slots open) to an ordered waitlist — cancelled messages are purged immediately when a slot opens, so new messages no longer wait for dead slots.² Pause/resume support and external rate reconfiguration landed alongside. The GET /v2/flow-control endpoint now returns parallelismCount, rateMax, rateCount, ratePeriod, and ratePeriodStart, and the QStash Console added a Flow Control tab with a historical parallelism graph.

Sensitive data redaction shipped for QStash and Workflow. Publishing a message or triggering a workflow now accepts a redact field that zeros out body and/or specific headers in dashboard and API responses, replacing values with a REDACTED: prefix — directly addressing multi-tenant data-leak exposure.³

Workflow's TypeScript SDK fixed a notify race condition. Passing workflowRunId to notify stores the notification for delivery even if the workflow hasn't reached waitForEvent yet, eliminating the gap between trigger and wait.⁴

QStash added US and EU regional endpoints to reduce publish latency by routing requests to the nearest region.⁵
