 # Changelog
 
+## [0.6.7] - 2026-05-21
+
+Added:
+
+- `build.filename` and `build.extension` in `dcr.toml` — complete control over the final artifact name without relying on `package.name`.
+  Example:
+  ```toml
+  [build]
+  filename = "KERNEL"
+  extension = "EFI"
+  ```
+  Produces `KERNEL.EFI` (works for `bin`, `staticlib`, and `sharedlib`).
+- Automatic injection of `--target=<build.target>` into compiler flags when `build.target` is set in `dcr.toml`. This greatly simplifies clang-based cross-compilation (especially for bare-metal targets like `aarch64-none-elf`).
+- Bare-metal targets (containing `none`, `-elf`, `eabi`, `baremetal`) no longer receive DCR's internal default flags (`-g`, `-Wall`, `-Wextra`, `-fno-omit-frame-pointer`, `-DDCR_DEBUG`, etc.). Prevents unwanted sections (`.comment`, debug info, etc.) that break custom linker scripts when `inherit = true`.
+
+Fixed:
+
+- `build.target` declared in `dcr.toml` is now correctly used as the default target even when `--target` is not passed on the command line (previously the host target was always forced for config resolution).
+

 - Incremental rebuild checks source/object mtime and tracked header dependencies.
 - `--force` skips build cache checks and recompiles.
 - `--clean` removes `target/<profile>` and `build.clean` paths before building.
+- `build.filename` + `build.extension` allow full control over the final artifact name (e.g. `KERNEL.BIN` instead of using `package.name`).
 - Default GCC/Clang profile flags: `debug` -> `-O0 -g -Wall -Wextra -fno-omit-frame-pointer -DDCR_DEBUG`, `release` -> `-O3 -DNDEBUG`.
+  These defaults are **not applied** for bare-metal targets (e.g. `aarch64-none-elf`, targets containing `none` / `-elf` / `eabi`).

 - In workspace root, `dcr build` builds all members in dependency order.
 - `build.exclude` removes paths from source/header collection; `build.include` re-allows matching paths and has priority over `exclude`.

+# dcr tree
+
+Displays a visual dependency tree for the current project (similar to `cargo tree`).
+
+## Usage
+
+```sh
+dcr tree
+dcr tree --invert
+dcr tree -p some-package
+```
+
+## What it shows
+
+- All direct and transitive dependencies
+- Version of each dependency
+- Whether a dependency is a registry, git, or path dependency
+
+## Notes
+
+- Useful for debugging dependency issues and understanding the build graph.
+- Output format is inspired by `cargo tree`.
