v2.2.3

Added

• Neovim text editor.

See CHANGELOG.md

v2.2.2

Fixed

• Added empty libiconv.a stub in Dockerfile to satisfy -liconv at link
  time. On glibc systems (Ubuntu), iconv is built into libc and there is no
  separate libiconv package, but GNATCOLL iconv links -liconv explicitly.
• Added binutils package to Dockerfile for ar command used to create the stub.

v2.2.1

Added

• "Embedded Board Support" section in README with board table and two
  readiness tables (Alire image vs System image) showing Ada compiler and
  C cross-compiler availability per target.
• alr/gprbuild configuration examples in USER_GUIDE §0.4 for all four
  target/image combinations (desktop Alire, desktop System, Cortex-M7
  bare-metal, Cortex-A7 Linux).

Fixed

• README badges placed on a single line for correct inline rendering.

v2.2.0

What's New

Added embedded development toolchain to both images, supporting bare-metal ARM Cortex-M and Linux ARM Cortex-A development.

Added

• ARM Cortex-M bare-metal cross-compiler (gcc-arm-none-eabi, libnewlib-arm-none-eabi) for STM32F769I and similar boards.
• ARM Cortex-A Linux cross-compiler (gcc-arm-linux-gnueabihf, libc6-dev-armhf-cross) for STM32MP135F and similar boards.
• Hardware tools: openocd, stlink-tools, gdb-multiarch.
• Embedded board support table in README and USER_GUIDE §0.4.

Embedded Board Support

Board	SoC	Core	Runtime	Cross-compiler
STM32F769I Discovery	STM32F769NI	Cortex-M7	Bare metal	arm-none-eabi-gcc
STM32MP135F Discovery	STM32MP135F	Cortex-A7	Linux	arm-linux-gnueabihf-gcc

v2.1.2

Added

• Makefile convenience aliases: docker-pull, docker-pull-system,
  podman-pull, podman-pull-system.

make docker-pull-system   # pull from GHCR with docker
make docker-run-system    # run it

v2.1.1

Added

• Makefile pull and pull-system targets that pull from GHCR and tag for
  local use, so make run / make run-system work without building locally.

make pull-system    # pulls from GHCR, tags locally
make run-system     # just works

v2.1.0

Multi-Architecture Support

The system toolchain image (Dockerfile.system) now builds for both
linux/amd64 and linux/arm64 (Apple Silicon). Docker pulls the native
variant automatically.

Architecture Compatibility

Image	Base	alr (amd64)	alr (arm64)	GNAT (amd64)	GNAT (arm64)
Dockerfile	Ubuntu 22.04	Works	Fails (glibc 2.38)	Alire-managed	Not available
Dockerfile.system	Ubuntu 24.04	Works	Works	gnat-13	gnat-13

Verified Test Matrix

Image	Ubuntu VM (amd64)	macOS Intel (amd64)	MacBook Pro (arm64)
dev-container-ada	Passed	Passed	N/A (amd64 only)
dev-container-ada-system	Passed	Passed	Passed

Other Changes

• Makefile: full system image target parity (run-root-system, save-system, tag-system, etc.)
• Makefile: help text reorganized by image variant with architecture info
• CI: QEMU + buildx with per-matrix platform selection
• Docs: architecture tables in README, USER_GUIDE references README

See CHANGELOG.md for the complete list.

v2.0.1

Summary

Code review fixes and polish for v2.0.0.

Fixed

• Moved # syntax=docker/dockerfile:1.7 to line 1 in both Dockerfiles so BuildKit uses the specified frontend.
• Added entrypoint.sh to build context file lists in Dockerfile headers.
• Removed orphan examples/hello_ada/hello_ada.adb; added copyright header to src/ copy.
• Reject HOST_USER=root and HOST_UID=0 in entrypoint to prevent root account modification.
• Added logging to fixup_symlinks() for toolchain relink visibility.
• Fixed alire.toml author, maintainer, login, website, and "tdb" typo.
• Fixed USER_GUIDE version mismatch (2.1 → 2.0.0).

Added

• Makefile targets test-system, test-docker-system, test-podman-system for system-image testing.
• make -f usage note in README explaining CURDIR bind-mount behavior.

Changed

• Unified CI build steps into a single matrix-driven step.
• CI smoke test now matches Makefile test scripts.

Full Changelog: v2.0.0...v2.0.1

v2.0.0

What's New

Two-Dockerfile split: ship both an Alire-managed toolchain image and a system-packaged toolchain image.

Added

• Dockerfile.system for Ubuntu 24.04 with system-packaged GNAT and GPRBuild.
• Makefile targets: build-system, build-system-no-cache, run-system.
• CI matrix build for both Dockerfile variants in docker-build.yml.
• Two-job publish workflow (publish-alire + publish-system) in docker-publish.yml.
• USER_GUIDE §0 "Choosing a Dockerfile" with rationale and guidance.
• Alire configured with gnat_external in system image so alr build uses the system compiler without downloading toolchains.

Changed

• BREAKING: Default Dockerfile base image from Ubuntu 24.04 to Ubuntu 22.04, matching the platform Alire's GNAT toolchains are built on.
• GitHub Actions pinned by SHA digest for supply-chain security.
• Documentation updated throughout for dual-Dockerfile structure.

v1.0.2

v1.0.2 — macOS UID Compatibility

Fixed

• Suppressed useradd warning for macOS UIDs below 1000 (e.g., UID 501). Added -K UID_MIN=100 -K UID_MAX=65534 to useradd and -K GID_MIN=100 -K GID_MAX=65534 to groupadd in the entrypoint.
