# OpenObserve v1.0.0 Release Notes

**Download Binaries**: https://openobserve.ai/downloads

**Release Date**: September 11, 2026
**Previous Version**: v0.92.2

---


## Highlights

**v1.0.0 brings you v1.0 of AI Observability.** OpenObserve's end-to-end observability for LLM and agent workloads is now first-class: trace and session evaluations, an eval scheduler, annotation queues and datasets, a **Playground** with execution and scoring, **experiment workflows**, conditional model pricing, and a hardened **agent/service graph**. AI Observability is the defining story of this release — everything you need to monitor, evaluate, and debug AI systems ships in the v1.0 line.

Beyond AI Observability, v1.0.0 is OpenObserve's first **1.x General Availability** release, spanning **375 commits** (295 OSS + 80 enterprise) since the v0.92.2 line. It lands a major expansion of **alerting and reliability**: brand-new **SLOs (Service Level Objectives)** with burn-rate alerts and PromQL/time-sliced targets, **composite alerts**, an **alert library** for browsing, previewing and bulk-installing curated alerts, **multi-alert for SQL** and **pending periods**, plus **Terraform/OpenTofu export** for alerts and SLOs.  This release also introduces **Database Monitoring (DBM)**, moves **Synthetic Monitoring fully into open source** with super-cluster support and step-based billing, and lands substantial **PromQL performance** work. Under the hood, the storage layer split into **separate ORM read/write clients** (retiring the sqlite write lock), and the platform saw a broad **i18n, UI-token, and search-cancellation** hardening pass.

### Performance
