Vector v0.11.0 release notes

Upgrading Vector
When upgrading, we recommend stepping through minor versions as these can each contain breaking changes while Vector is pre-1.0. These breaking changes are noted in their respective upgrade guides.

The Vector team is pleased to announce 0.11.0. This release is focused on Kubernetes. In addition to the new, first-class Kubernetes integration, we launched a number of complementary features that make Vector a prime candidate for collecting and processing your Kubernetes logs. Check out the highlights and changelog for more details.

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. This will likely be the focus of 0.13.
Kubernetes aggregator role
In addition to Vector’s observability, 0.12 will include support for deploying Vector into the aggregator role within Kubernetes. This will allow you to build end-to-end observability pipelines in Kubernetes with Vector. Distributing processing on the edge, centralizing it with an aggregator, or both. If you are interested in beta testing, please join our chat and let us know.
Vector Remap Language (VRL)

Finally, 0.12 will introduce the new Vector Remap Language. This is a Rust-native syntax designed for safe and efficient data mapping. It’s an ultra-performant middle ground between fundamental transforms like add_fields and a full blown runtime like lua.

If interested, you can beta test via the remap transform and use the Vector Remap Language reference to write scripts.
