Server v4.x offers the following:

  • Greatly improved security handling, installation, and update processes.

  • Installed using Helm charts and images that can be pulled ahead of time to comply with your security processes.

  • Installation processes can use artifacts pulled from customer-managed registries.

  • Improved use of Kubernetes secrets and removes the requirement to grant permissions and network access to third-party tools.

Migrate from v3.x to v4.x

For existing customers interested in migrating from v3.x to v4.x, or v2.x to v4.x contact your customer success manager. Server v4.x will receive monthly patch releases and quarterly feature releases.
