Upbound product changelog

Product update 2023-10-24

What’s Changed

• Improved the control plane dashboard and configuration list by making the table headers sticky, allowing users to scroll through longer lists without losing context.
• Resolved an issue affecting Configurations with dependencies on the latest releases of family providers that prevented users from creating new ProviderConfigs via the UI.
• The console now shows UI create hints on the control plane and configuration list screens for organizations with no control planes or configurations created.
• We fixed the background color of the main navigation tabs to match the page.
• The UI tabs in a managed control plane dashboard now link via url hash. For example, the settings tab renders as console.upbound.io/org/controlPlanes/org:ctp-name#resources

Spaces release notes

Spaces v1.2.4

Released March 13rd, 2024.

What’s Changed

• Tweaked the control plane API autoscaler configuration per recent performance testing.
• Fixed an issue causing the kube-state-metrics pods being restarted per CRD deployed in the control plane.
• Optimized the control plane deletion process to reduce the time it takes to delete a control plane.
• Fixed an issue breaking kubectl logs command against the control plane API.

Spaces v1.2.3

Released March 1st, 2024.

What’s Changed

• This release fixes an issue that affected control planes’ ability to provision in non-kind cluster environments.

Spaces v1.2.2

Released March 1st, 2024.

What’s Changed

• This release contains several improvements to improve control plane orchestration performance. It addresses an issue where control plane provisioning time degraded when multiple control planes were provisioned in parallel.
• The latest supported minor Crossplane version is now v1.15.

Spaces v1.2.1

Released February 8th, 2024.

What’s Changed

• Fixed an issue causing the controlplane resources having a benign crossplane.io/external-create-failed annotation.
• Fixed an issue causing hotlooping version controller when a controlplane is deleted.
• Other stability and performance improvements.

Spaces v1.2.0

Released February 1st, 2024.

What’s Changed

• We introduced a new concept called control plane groups within a Space. Technically, all kind: controlplane resources are now namespace-scoped objects (as opposed to previously being cluster-scoped).
• Control planes now offer auto-upgrade channels (rapid, stable, patch, and none), giving users control over what pace their control plane’s Crossplane version automatically upgrades to. None gives users total control over when to upgrade the Crossplane version in a managed control plane.
• Alpha suppport for a new aggregate query API that can be used to query state across one or more control planes in a group.
• Alpha support for built-in multi-control plane secrets management. Define new SharedSecrets and SharedSecretStores within a control plane group to selectively provision secrets from an external store–such as Vault–into the control planes in the group.
• Support for OIDC auhentication flows when interacting directly with a managed control plane in a Space.
• new up CLI commands to migrate open soure Crossplane or UXP instances into a managed control plane in a Space.

Spaces v1.1.0

Released October 10th, 2023.

What’s Changed

• Alpha support for enabling External Secrets Operator in a control plane.
• Control plane api-server autoscaling based on CRD count.
