v1.98.0 Release Notes

Deprecations

• PodSecurityPolicies: Opencost and Kubecost now both support kubernetes v1.25. However, by default, certain PodSecurityPolicies are still installed. These will be removed in v1.99 to streamline installation on v1.25. Meanwhile, you can still install Kubecost on v1.25 via this helm chart with the following instructions: #1773 (comment)

Major

• Launched Kubecost Cloud beta
• Launched free unlimited clusters
• Launch new UI Beta
• *Doc Container Request Right Sizing recommendation API V2 Beta
• Persistent Volume Right Sizing insights beta
• ETL Query Scaling APIs to improve allocation filtering performance at scale!
• 1700 Launch of federated ETL pipeline Beta Docs

Note: * Percentile-based request right-sizing recommendations are available in the Beta UI, but only if the "ContainerStats" data pipeline is enabled. This pipeline may have trouble at high data scales while it is in the early stages of development -- please carefully review the relevant documentation: https://github.com/kubecost/docs/blob/main/api-request-right-sizing-v2.md
