Changelog

0.7.0 (2026-06-01)​

Added​

  • OpenBSD and NetBSD target support — full platform routing with dynamic target triples using std::env::consts::ARCH and std::env::consts::OS. Affects build, run, clean commands and the platform module.
  • src/platform/bsd.rs — new BSD platform module (shared by FreeBSD, OpenBSD, NetBSD) providing bin_path, lib_path, elf_path, efi_path, shared_lib_path.
  • build.out_dir config option — custom output directory that overrides the default target/<triple>/<profile> path for final artifacts. Supported in build, run, and config validation.
  • dcr fmt command — new CLI command that formats all C/C++ source files (*.c, *.cpp, *.h, *.hpp) in src/ and tests/ using clang-format.
  • Incremental linking — needs_link() in common.rs checks if any object file is newer than the linked output, skipping unnecessary relinking. Implemented for all backends (unix_cc, msvc, gas, nasm).
  • build.kind = "none" and "custom" — two new project kinds for special build scenarios that don't produce standard artifacts.
  • install_bsd.sh — POSIX-compliant installation script for BSD systems (FreeBSD, OpenBSD, NetBSD) with binary download and source build modes.
  • Linux ARM64 support in install.sh — added Linux:aarch64|Linux:arm64 target detection for pre-built binary downloads.
  • BSD OS detection in install.sh — detects FreeBSD, OpenBSD, NetBSD and determines target triple.
  • rust-toolchain.toml — explicit toolchain pinning to stable channel.
  • Integration tests — build_with_target_config (verifies build.target = "linux") and build_with_out_dir (validates custom output directory).
  • get_build_string_with_profile made pub — so run.rs can determine custom output directory configuration.

Changed​

  • build.target semantics changed — now strictly contains a target triple (e.g., x86_64-unknown-linux-gnu) or short name (linux, macos, windows). No longer used as custom output directory — this functionality moved to build.out_dir.
  • build.standard made optional — changed from String to Option<String>. Validation only enforces non-empty for non-ASM languages. Skipped in dcr.toml output if empty.
  • dcr run with out_dir — now determines target directory respecting build.out_dir via get_build_string_with_profile() from build.rs.
  • collect_sources() returns empty vector instead of error when no sources are found, allowing kind = "none" or kind = "custom" projects with no source files.
  • CI/CD release workflow refactored — git2 made target-specific (no vendored-openssl on Windows), Zig-based cross-compilation for non-x86_64 Linux targets, Arch Linux package version cleanup (dashes → dots), gmake symlink for NetBSD.
  • README compatibility table — FreeBSD, OpenBSD, NetBSD build/run status upgraded from "community/best-effort" to "officially supported".
  • Documentation updated — build-section.md describes new build.target and build.out_dir fields. target-directory.md rewritten to clarify the distinction.

Fixed​

  • stdout/stderr not inherited in dcr run — child process output was captured and manually printed, breaking interactive programs. Fixed by switching to Command::status().
  • Race condition in release CI — matrix build jobs could upload assets to a release that didn't exist yet. Fixed by adding a dedicated create-release job.
  • Release GHA — stable toolchain override — fixed Rust toolchain override issues in CI.
  • Arch Linux package version sanitization — version strings with dashes (e.g., 0.7.0-dev) are invalid for pkgver. Fixed by replacing dashes with dots.
  • GPG permissions after Docker — Docker operations changed GPG directory ownership. Fixed by running chown after Docker commands.
  • RPM artifact paths — RPM artifacts were placed in rpm/x86_64/ instead of fedora/x86_64/. Fixed in Dexoron Packages Index workflow.
  • JSON parsing reliability in install.sh — added jq as primary parser with python3 fallback for dev channel release lookup.

Removed​

  • format_roots() helper function — removed from common.rs. Was only used by the old error handling path in collect_sources().
  • Per-distribution artifact download steps — three separate actions/download-artifact steps replaced with unified gh release download --clobber.
