v1.1.0

Major Themes

This is the first post-v1.0 release for Crossplane, and also serves to establish our new release cadence. Crossplane will continue with minor version releases every 2 months for the foreseeable future, and the community will maintain the most recent 3 releases.

v1.1.0 primarily adds additional functionality to Crossplane's composition engine and enhances the ability to customize provider installations.

Notable Updates

• #2077 Adds "bidirectional patching" to Crossplane's composition engine. This allows for specifying patches from composed resources back to the corresponding XR / XRC. You can read more about this feature in the composition documentation. Thanks to @mcavoyk for delivering this feature.
• #2104 Adds the ability to set annotations on an installed provider controller Pod using the ControllerConfig API type. This enables scenarios such as credential injection using the Vault sidecar agent.
• #2133 Added support for Required fromFieldPath patches, which will cause rendering of composed resources to fail if a patch that is marked as Required is missing its fromFieldPath. This can have interesting implications when interacting with bidirectional patching, and its behavior is subject to change slightly in the future. See #2175 for more information.
• #2131 Adds support for naming templates in a Composition. This enables reordering, as well as addition and deletion of templates in a Composition. Template names are not required, but all templates in a
• #2082 Update Crossplane dependency on controller-runtime to v0.8.0. This change does not result in any user-facing changes for Crossplane users, but does include some fixes in the underlying machinery. Thanks to @saschagrunert and @khos2ow for leading this update.
• #2087 Fixes a bug with required package revision dependency status fields by making them optional. This bug impacted users upgrading from pre-v1.0 Crossplane versions, but could be mitigated by manually removing the required stanza in the status of the CRD.
• #2061 Adds support for linux_arm binaries and images, and switches to using a distroless base image for Crossplane and the RBAC Manager.
• #2102 Added support for using the Kubernetes Lease API for leader election for Crossplane and any providers it installs. controller-runtime currently supports using a Multilock strategy for leader election, meaning that both the legacy ConfigMap strategy, as well as the Lease API, are supported.
• #2105 Adds parameters to the Crossplane Helm chart for setting nodeSelector, tolerations, and affinity on the Crossplane and RBAC Manager Deployments.
• #2134 Adds the ability to expose Prometheus metrics endpoints for installed providers using the ControllerConfig API type. Thanks to @smcavallo for enabling this functionality.

Upgrading

Upgrades from v1.0 should be seamless, but a little special handling is required due to the fact that Helm does not upgrade CRDs. See
the Upgrading to v1.x guide in the Crossplane documentation for more information.
