### What's new

**JavaScript Script task improvements**

The JavaScript Script task is now powered by Jint, aligned with the expression editor. This update removes the previous 10k inbound character limit and 1 MB outbound payload limit. Script tasks now support up to 64 MB of memory, a 30-second execution time limit, and the ability to expose transform functions.

**Pause support for Call activity**

You can now pause processes while a Call activity is running. Previously, a pause signal only took effect after the Call activity completed.

**RPA self-healing for missing activities**

When an RPA activity fails to start due to a missing resource (for example, a 404 error), Maestro now applies self-healing to recover execution and continue the process run.

In the Optimize tab, KPIs now include history charts, making it easier to track trends over time.
