Major Themes

The key theme of this release is performance and scalability. This release introduces a --max-reconcile-rate flag that controls how frequently Crossplane may reconcile its resources. With the default value of --max-reconcile-rate=10 (per second) Crossplane v1.6 is able to drive large bursts of claims (each composed of a handful of managed resources) to readiness 2x to 5x faster than Crossplane v1.5.

Note that this release removes the following v1beta1 APIs:

  • Provider.pkg.crossplane.io/v1beta1
  • ProviderRevision.pkg.crossplane.io/v1beta1
  • Configuration.pkg.crossplane.io/v1beta1
  • ConfigurationRevision.pkg.crossplane.io/v1beta1
  • CompositeResourceDefinition.apiextensions.crossplane.io/v1beta1
  • Composition.apiextensions.crossplane.io/v1beta1

Upcoming API Removals

Note that v1.6 will be the lat version of Crossplane that supports the following v1alpha1 APIs, which will be removed in v1.7. Please migrate to the v1 iteration of these APIs if you have not already. The v1alpha1 and v1 APIs are identical, so migration should simply be a case of updating the apiVersion in your packages:

  • Provider.meta.pkg.crossplane.io/v1alpha1
  • Configuration.meta.pkg.crossplane.io/v1alpha1
