# Cortex Renderer 1.3.0

**October 13, 2022**

## New features

### Scalability

Cortex Renderer 1.3.0 adds the ability for it to scale horizontally. Previously, only a single instance of the service could be running and now the service is able to replicate based on load. This improves job throughput, and prevents heavier jobs from degrading the performance of lighter jobs. This scalability is achieved by persisting job state in Cortex's database so that any job may be handled by any service instance.

## Resolved items

* The cortex renderer does not execute the provided callback for certain long running jobs.
