+A milestone release introducing LocalGPT Gen for 3D scene generation, XDG Base Directory compliance, Docker Compose support, and workspace restructuring.
+
+### Added
+
+- **LocalGPT Gen** — a new `localgpt-gen` subcrate for AI-driven 3D scene generation (Phase 1+2). ([55aa127](https://github.com/localgpt-app/localgpt/commit/55aa127))
+- **Secure Docker Compose setup** for running LocalGPT in containers. ([#2](https://github.com/localgpt-app/localgpt/pull/2))
+- **XDG Base Directory layout** for all paths, following platform conventions on Linux, macOS, and Windows. ([#18](https://github.com/localgpt-app/localgpt/issues/18))
+- **Local server config guidance** for OpenAI-compatible server setups. ([#25](https://github.com/localgpt-app/localgpt/pull/25))
+- Security section added to README covering sandbox, signed policy, and injection defenses.
+
+### Changed
+
+- Extracted `localgpt-gen` into its own workspace member and bumped to v0.2.0.
+- Replaced OpenClaw auto-migration with a detection notice (no longer silently migrates config).
+- Configured cargo-release for joint crates.io publishing.
+
+### Fixed
+
+- Added glibc compatibility shim for `ort-sys` on glibc < 2.38 (fixes builds on older Linux distros).
+
