Cost
- Fix: PV costs are no longer incorrectly duplicated in the event of a PVC being shared by multiple pods
- Fix: Savings summary and request sizing no longer double-apply discounts
- Fix: Idle costs were incorrect when filters are applied and adjustments are present
- Fix: Prometheus and Thanos clients handle rate limit responses, including AWS AMP 400 special-case throttling
- Fix: Avoid a nil panic in an Athena query failure edge case
- The abandoned workloads endpoint will fail more quickly in the event of bad data
- Reduced memory impact on startup for cloud asset/reconciliation processes
- Reduced memory impact for AWS users with cloud asset/reconciliation enabled
- Support for alert testing
- Fix: "/model/explainCA" no longer returns garbled error messages
- Fix: "/model/explainCA" returns HTTP error statuses for errors
- Kubecost's backing schema can be upgraded without rebuilding the ETL
- Fix: recurring alert duration now reported correctly
- Allocation API supports the "accumulateBy" parameter
Frontend
- Allocation: New treemap visualization of allocation data
- Diagnostics: Max and average node count, as calculated by Kubecost, visible
- Inspect: Support for label aggregation
- Allocation: Page now includes a link to Kubecost official documentation
- Savings: Fixed some mangled URLs
- Savings: savings.html should load more quickly and more stably
- Alerts: UI reworked for usability and adds alert testing functionality
- SAML: Logout button
- Overview + Savings: savings estimate being slow will not break the page (instead loading partially)
- Allocation: "NaN%" is replaced with "-" for external_resources
- Inspect: Useful failure message when data isn't available to display
- Allocation: On the details drilldown for an individual pod, the row values were being too-aggressively rounded to 2 decimal places while displaying 3. The values are now rounded to 3 decimal places.
- Cloud connection status: fixed "No Connection" status bug
