 ### Key Concepts

- **`dcr.toml`** — конфигурационный файл проекта (аналог `Cargo.toml`). Секции: `[package]`, `[build]`, `[toolchain]`, `[dependencies]`, `[workspace]`.
- **Профили сборки**: `debug` (по умолчанию) и `release`. Встроенные флаги зависят от компилятора. Пользовательские флаги через `build.cflags` / `build.ldflags`.
- **Инкрементальная сборка**: объектные файлы кешируются по mtime. Отслеживание заголовков пока не реализовано (см. `TODO.md`).
- **Workspace**: корневой `dcr.toml` с секцией `[workspace]` описывает member-проекты и их зависимости; сборка происходит в топологическом порядке.
- **Path dependencies**: зависимости по путям автоматически добавляют include/lib-пути; генерируется `dcr.lock`.
- **Build kinds**: `bin` (бинарник), `staticlib` (`.a`), `sharedlib` (`.so`/`.dylib`/`.dll`).
+- **`~/.dcr/`**: Centralized storage for registries and configurations.
+- **`config.toml`**: File in `~/.dcr/` defining available package indices and their priorities.
+- **`dcr.toml`**: Local project configuration.
+- **Registry System**: `RegistryManager` handles package discovery across multiple indices based on priority.

 # Changelog

+## [0.6.5] - 2026-05-13
+
+Added:
+
+- New dependency registry system
+- Package type support (`lib`, `app`, `none`) in `dcr.toml`
+- Library packaging functionality: automatically generates `include` and `lib` directories in `target/` for `lib` type projects
+- Expanded CI build targets:
+  - Linux: `aarch64-unknown-linux-gnu`, `x86_64-unknown-linux-musl`, `aarch64-unknown-linux-musl`
+  - Windows: `aarch64-pc-windows-msvc`, `x86_64-pc-windows-gnu`, `aarch64-pc-windows-gnullvm`
+
+Changed:
+
+- `src/core/deps/` modular architecture overhaul
+- Native platform pathing defaults for Linux (now dynamic architecture detection)
+- Improved `run` command output handling
+
+## [0.6.0] - 2026-05-12
+
+Added:
+
+- Full Git dependency support in `dcr.toml`
+  - Support for `git`, `branch`, `tag`, and `rev` fields
+  - Automatic cloning and checkout via `git2`
+  - Dependencies are stored in `target/<profile>/deps/git/`
+- New `dcr add` command for easy dependency management
+  - Short syntax: `github:user/repo`, `gitlab:user/repo`, `path:/to/lib`
+  - Automatic GitHub resolution for `git:user/repo`
+- Visual feedback for dependency fetching with in-place status updates ("Fetching" → "Fetched")
+- Modular dependency management architecture in `src/core/deps/`

+Priority list of tasks to turn DCR into a true Cargo killer for C/C++ developers.
+
+## 🔥 High Priority (Next Releases)
+
+- [x] **Git dependencies support**  
+  `git = "https://github.com/user/repo.git#branch"` and `git = "..."@tag`
+- [ ] **Conan and vcpkg integration**  
+  Automatic download, installation and linking of packages
+- [ ] **Full freestanding / embedded support**  
+  `-nostdlib`, linker scripts, bare-metal targets (i686-elf, aarch64-none-elf, etc.)
+- [ ] **EFI support**  
+  Dedicated platform configuration for EFI targets
+- [ ] **Custom project name**  
+  Override binary name in `dcr.toml`
+- [ ] **Custom build steps / targets**  
+  Ability to define custom pre-build, post-build, codegen steps in `dcr.toml`
+- [ ] **Improved mixed C/C++/ASM projects**  
+  Better handling of `.S` and `.asm` files with correct flags
+- [ ] **dcr publish + official package registry**  
+  Publish and fetch your own libraries easily
+
+## ✅ Medium Priority
+
+- [ ] **Static analysis** (`dcr check`)  
+  Integration with clang-tidy, cppcheck, include-what-you-use
+- [ ] **Linter + Formatter** (`dcr fmt`, `dcr lint`)
+- [ ] **Hot reload / Live reload** for applications (raylib, SFML, SDL, etc.)
+- [ ] **Better cross-compilation experience**  
+  Ready-to-use toolchains + automatic download
+- [ ] **Linker script support** + direct linker control
+- [ ] **Workspaces improvements**  
+  Per-member include directories, selective builds, better dependency graph
+- [ ] **Build-time code generation**  
+  Support for protobuf, flatbuffers, Qt moc, custom generators
+
+## 📌 Low Priority / Nice to Have
+
+- [ ] Support for Meson and Ninja as alternative backends
+- [ ] Dockerfile generation (`dcr docker init`)
+- [ ] First-class Windows MSVC support (currently works but rough)
+- [ ] Documentation generation (`dcr doc`)
+- [ ] Sanitizers integration (`dcr sanitize`)
+- [ ] Benchmarks and comparison with CMake/Meson
+- [ ] C++20 modules support (when it becomes stable)
+
+## 🧠 Future Ideas
+
+- Official DCR package registry (dcrhub)
+- GUI wrapper (dcr-gui)
+- Plugin system
+- Toolchain manager (like rustup)
+- Zig as alternative compiler
+- deb/rpm/flatpak/AppImage packaging support
+

+**Currently in progress:**
+- ...
+
+**Completed in recent releases:**

-## Supported fields per dependency
+## Supported dependency types

+### Registry dependencies
+Defined by name and version string. DCR automatically resolves the package from the configured registry index.
+
+### Git dependencies
+Defined by repository URL and optionally branch, tag, or revision.
+- `git` (string, required): repository URL.
+- `branch`, `tag`, `rev` (string, optional): Git reference.
+
+### Path dependencies
 - `path` (string, required): absolute path or path relative to project root.
 - `include` (string array, optional): include directories inside dependency.
 - `lib` (string array, optional): library directories inside dependency.
 - `libs` (string array, optional): library names for linker.
- `system` (bool, optional): currently `system = true` is rejected.

 - `version` (string, required): used in `dcr.lock` project entry.

 ## Notes

 - Empty `name` or `version` makes config invalid.
 - `dcr new` sets `name` from the passed project name.
 - `dcr init` sets `name` from current directory name.
