+### Added
+- **Deployment Tooling (cargo-rustapi)**: Added `deploy` command supporting Docker, Fly.io, Railway, and Shuttle.rs with config generation. Added OpenAPI client generation for Rust, TypeScript, and Python. Updated dependencies for YAML support and remote specs.
+- **HTTP/3 (QUIC) Support (rustapi-core)**: Added HTTP/3 infrastructure using Quinn + h3 stack. Supports self-signed certs (dev) and dual-stack execution. Added `http3` and `http3-dev` features.
+- **HATEOAS & ReDoc Improvements**: Added HATEOAS module to `rustapi-core` (HAL-style links, resource wrappers, pagination). Refactored ReDoc HTML generation in `rustapi-openapi` with exposed configuration.
+- **Validation i18n & New Capabilities**: Added i18n support (rust-i18n) with EN/TR locales in `rustapi-validate`. Refactored rule messages to use message keys. Added custom async validation support (parsing, macros, tests). Removed `validator` crate dependency.
+
+### Changed
+- **Unified Response Body**: Refactored `rustapi-core` to use a unified `Body`/`ResponseBody` abstraction for full and streaming responses. Standardized middleware and cache layers.
+- **Streaming Behavior**: Clarified flow behavior for streaming responses (e.g., explicit `Transfer-Encoding: chunked`).
+- **Server Lifecycle**: Added graceful shutdown signal method for better lifecycle control.
+- **OpenAPI Path Params**: Added support for custom schema type overrides for path parameters via `#[rustapi::param]` and `.param()`.
+
+### Fixed
+- **Validation Groups**: Fixed logic for default group application and context boundaries.
+- **Circuit Breaker**: Fixed syntax error in `circuit_breaker.rs`.
+- **OpenAPI**: Improved param schema/type handling; fixed UUID path param integer display bug (#55).
+
+### Documentation
+- **Traits**: Reorganized trait documentation examples.
+- **Cookbook**: Added deployment and HTTP/3 documents.
+- **General**: Updated crate pages and README contact info.
+
+### CI / Tooling
+- **Coverage**: Added GitHub Actions job for coverage generation with `cargo-tarpaulin`.
+
+### Chores
