# December 2024 Release

The December release of <code class="expression">space.vars.company\_name</code> <code class="expression">space.vars.PRODUCT\_NAME</code> includes several feature updates and enhancements.

### Key Features

**Cluster blueprints got a major upgrade**

The Cluster blueprint feature that enables a profile-based / declarative mechanism for defining the desired state of a Virtualized Cluster received a major upgrade in this release. You can now define multiple host configurations as part of the Cluster Blueprint, rather than standardizing on a single host configuration. This enables you to incorporate the diversity of infrastructure in your data center under a single Virtualized Cluster.

**Automatic Resource Rebalancing (ARR) enhancement**

ARR feature now utilizes both CPU and Memory metrics while making decisions on VM distribution on the Virtualized Cluster.
