v0.10.0-rc.3 - 2026-04-10 Pre-release

Pre-release

Highlights

Performance Mode: Subquery-based SLO Calculations #1607

SLO burn rate calculations can now use subqueries instead of recording rules, significantly reducing the number of rules Prometheus needs to evaluate and store.

Alert Severity Overrides #1788

Alert severities for multi-burn-rate alerts are now configurable directly in the SLO spec, giving teams full control over how alerts are routed and prioritized.

Prometheus v3 Histogram Support (`le` normalization) #1619

Pyrra now correctly handles the le label normalization differences between Prometheus v2 and v3 native histograms, enabling seamless migration to Prometheus v3 for latency-based SLOs.

`pyrra_url` Annotations on Alerts #1522

All generated alerts now include a pyrra_url annotation that links directly to the relevant SLO page in the Pyrra UI, reducing time from alert to context.

UI Redesign: shadcn/ui + Tailwind CSS #1789

The UI has been migrated from Bootstrap to shadcn/ui and Tailwind CSS, laying the groundwork for new UI features going forward.
