Vector v0.12.0 release notes

Code name Vector Remap Language

The Vector team is pleased to announce 0.12.0. This release introduces the Vector Remap Language, an expression-oriented language designed for transforming observability data (logs and metrics) in a safe and performant manner.

Check out the VRL announcement post for more details as well as the highlights and changelog for a complete list of changes in 0.12.0.

What’s next

Vector's own observability
We will be working to improve Vector’s own observability with high-quality internal metrics, logs, CLI tools, and dashboards.
Improved Vector to Vector communication
The vector source and sink currently use the TCP protocol to transmit data. While this has served users well, it presents operational challenges for large-scale deployments of Vector. Because HTTP is widely used and easy to integrate into platforms like Kubernetes we will be moving these components to the HTTP protocol.
Schema support
With the inclusion of type-safety in VRL we will be working to officially support common and custom schemas within Vector. This will be an opt-in feature that will provide Vector with type information about your data, making Vector type safe from end to end and further raising confidence that Vector will operate properly post-deployment.
