v26.4.0

🎉Announcement 🎉

We’re excited to announce the General Availability (GA) of the official rewrite of this tool: GoKubeDownscaler! The version 1.3 of GoKubeDownscaler brings all the features present in PyKubeDownscaler but in a Go Flavor!

Users can expect significant performance improvements, a reduced resource footprint, new features to support high availability and platform setups such as leader election, annotation compliance and so on. The new tool also comes with enhanced metrics and observability.

PyKubeDownscaler will remain supported for users who prefer not to migrate, with ongoing dependency updates, security patches, and bug fixes to ensure stability and reduce vulnerabilities. However, all new features and quality-of-life improvements will be developed in the new project.

🚀 Release Notes 🚀

• Upgraded project dependencies and the Docker image to address security vulnerabilities
• Introduced HPA safeguards to ensure that minReplicas cannot exceed maxReplicas during scale-up. This situation could previously occur when other tools were also modifying HPA objects
• Introduced logic to remove potential stale annotations
• Improved TokenBucket Logic

v25.11.0

🚀 Release Notes 🚀

• Logs are now redirected to Stderr following input/output global standards
• Logs can now be printed in JSON format using the new argument --json-logs. JSON logs are also natively compatible with GCP Cloud Logging specifications
• Added support for global DEFAULT_WEEKFRAME and DEFAULT_TIMEZONE environment variables, allowing users to define a default weekframe and timezone (e.g., Mon-Fri, Europe/Paris). This lets individual time settings be simplified to entries like DEFAULT_UPTIME=08:00-20:00 or downscaler/uptime=08:00-20:00, with the weekframe and timezone automatically inferred from the global variables.
• PriorityClass can now be set directly from the Helm Chart values
