 All notable changes to Agents.KT are documented here. The format follows [Keep a Changelog](https://keepachangelog.com/en/1.1.0/), and the project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html). Pre-1.0, minor bumps may add new public API; existing API surface is preserved.
 
-## [Unreleased] — targeting 0.3.0
+## [0.3.0] — 2026-05-05
 
 First leg of the **KSP / compile-time-validation initiative** described in `docs/ksp-design.md`. This release ships **typed tool refs** — Kotlin's type system catches `tools("typo")` mistakes that previously bombed at agent `validate()` (or in CI test runs). Plus the `:agents-kt-ksp` module skeleton, ready for the Phase 2 codegen work.
