|
|
- **Cloud Foundry**. Added minimum Pilot support for the [Cloud Foundry](https://www.cloudfoundry.org) platform, making it
|
|
possible for Pilot to discover CF services and service instances.
|
|
|
|
- **Circonus**. Mixer now includes an adapter for the [Circonus](https://www.circonus.com) analytics and monitoring platform.
|
|
|
|
- **Pilot Metrics**. Pilot now collects metrics for diagnostics.
|
|
|
|
- **Helm Charts**. We now provide Helm charts to install Istio.
|
|
|
|
- **Enhanced Attribute Expressions**. Mixer's expression language gained a few new functions
|
|
to make it easier to write policy rules. [Learn more](/docs/reference/config/policy-and-telemetry/expression-language/)
