# What's new and versions

*Applies to VAST Cluster 5.5.*

These docs are written for **VAST Cluster 5.5**. Every page says so under its title, and describes only what 5.5 ships. If your cluster runs another release, check the release notes and version pages below before you rely on a page.

## Find your cluster's release

Run the short check on [find your versions](/develop/docs/dev-database-reference-versions#find-your-versions): it prints your VAST DataBase Python SDK version and the cluster version. For DataEngine, ask your platform team which `vastde` CLI release and builder image go with your cluster ([your workstation](/develop/docs/dev-dataengine-operations-setup-prerequisites#your-workstation)).

## What's new in 5.5, by service

| Service | What's new | Versions and compatibility |
| --- | --- | --- |
| VAST DataBase | [Release notes](/develop/docs/dev-database-release-notes): what each 5.5 release added, fixed and limits | [Version compatibility](/develop/docs/dev-database-reference-versions): the Python SDK, Trino, Spark and the ADBC driver |
| VAST Vector Search | [Release notes](/develop/docs/dev-vector-search-release-notes): what 5.5 supports for vector search, and its known limitations | [Version compatibility](/develop/docs/dev-database-reference-versions), shared with VAST DataBase |
| VAST Event Broker | [What's new in 5.5](/develop/docs/dev-event-broker-overview#whats-new-in-55) | [Kafka compatibility](/develop/docs/dev-event-broker-reference-kafka-compatibility): supported clients and Kafka APIs |
| VAST DataEngine | [What's new in 5.5](/develop/docs/dev-dataengine-overview#whats-new-in-55) | [Your workstation](/develop/docs/dev-dataengine-operations-setup-prerequisites#your-workstation): the `vastde` CLI and builder image |
| VAST DataStore | No release-notes page | [S3 compatibility](/develop/docs/dev-datastore-reference-s3-compatibility) and [NFS versions](/develop/docs/dev-datastore-reference-nfs#versions) |
| VAST Catalog | No release-notes page. The [overview](/develop/docs/dev-catalog-overview#use-cases-and-considerations) lists what to know on 5.5. | The Catalog is read with the VAST DataBase clients: see [version compatibility](/develop/docs/dev-database-reference-versions) |

The full release notes are in the KB: [VAST Cluster 5.5 release notes](/docs-5-5/docs/vast-cluster-5-5-release-notes). The release-notes pages here are digests for people who build on the cluster.

## Automation tools

[Automation tools](/develop/docs/dev-database-reference-automation-tools) names the Terraform provider, `vastpy` and admin MCP server versions its examples were checked with on 5.5, and which [REST API versions](/develop/docs/dev-database-reference-automation-tools#api-versions) a 5.5 cluster serves.
