+### Added
+- **`env_nested_delimiter` implementation** - Previously declared but not functional, now fully implemented with delimiter-aware env var scanning, recursive type resolution, and nested dict unfolding (contributed by [@FatJun](https://github.com/FatJun) in [#49](https://github.com/msgflux/msgspec-ext/pull/49))
+- `env_nested_max_depth` config option to limit nesting depth (0 = unlimited)
+- `load_dotenv` exported in public API (`from msgspec_ext import load_dotenv`)
+- 10 new tests for nested delimiter functionality
+
+### Changed
+- `env_nested_delimiter` default changed from `"__"` to `None` (opt-in behavior)
+
+### Fixed
+- `env_nested_delimiter` was declared in `SettingsConfigDict` but never used ([#48](https://github.com/msgflux/msgspec-ext/issues/48))
