+
+[Workflows](/workflows/) is now _Generally Available_ (or "GA"): in short, it's ready for production workloads. Alongside marking Workflows as GA, we've introduced a number of changes during the beta period, including:
+
+* A new `waitForEvent` API that allows a Workflow to wait for an event to occur before continuing execution.
+* Increased concurrency: you can [run up to 4,500 Workflow instances](/changelog/2025-02-25-workflows-concurrency-increased/) concurrently (and this will continue to grow)
+* Improved observability, including new CPU time metrics that allow you to better understand which Workflow instances are consuming the most resources and/or contributing to your bill.
+* Support for `vitest` for testing Workflows locally and in CI/CD pipelines.
+
+Workflows also supports the new [increased CPU limits](/changelog/2025-03-25-higher-cpu-limits/) that apply to Workers, allowing you to run more CPU-intensive tasks (up to 5 minutes of CPU time per instance), not including the time spent waiting on network calls, AI models, or other I/O bound tasks.
+
+#### Human-in-the-loop
+
+The new `step.waitForEvent` API allows a Workflow instance to wait on events and data, enabling human-in-the-the-loop interactions, such as approving or rejecting a request, directly handling webhooks from other systems, or pushing event data to a Workflow while it's running.
+
+Because Workflows are just code, you can conditionally execute code based on the result of a `waitForEvent` call, and/or call `waitForEvent` multiple times in a single Workflow based on what the Workflow needs.
+
+For example, if you wanted to implement a human-in-the-loop approval process, you could use `waitForEvent` to wait for a user to approve or reject a request, and then conditionally execute code based on the result.

+```ts
+import { Workflow, WorkflowEvent } from "cloudflare:workflows";
