Releasing

This page is the operator guide for cutting an icey release.

Use it when you are preparing a new version, tagging it, and updating the package-manager artifacts that depend on the published GitHub source archive.

What Changes On A Release

A real icey release has two parts:

1. manual release prose
2. mechanical version and archive metadata

The manual part stays in:

• CHANGELOG.md
• ROADMAP.md

The mechanical part is handled by the top-level release helpers:

• make release
• make release-check
• make release-pin

Core Release Flow

Start from a clean, reviewed main branch with the release notes already written.

make release VERSION=2.4.0
git commit -am "release: prepare 2.4.0"
git tag 2.4.0
git push origin main 2.4.0
make release-finalize VERSION=2.4.0
git commit -am "build: pin release archives for 2.4.0"
git push origin main

What those steps do:

• make release syncs VERSION, package recipe versions, Debian source metadata, Conan release metadata, and the public FetchContent examples.
• make release-finalize pins the release archive hashes and then verifies that VERSION, package metadata, docs examples, and the matching CHANGELOG.md heading all line up.
• the release tag must be a plain semantic version such as 2.4.0
• the GitHub source archive for that tag is the thing the package-manager pinning steps use

Package-Specific Follow-Up

After the tag is pushed, the GitHub tarball becomes immutable. That is when archive hashes should be pinned.

The combined post-tag helper is:

make release-finalize VERSION=2.4.0

That runs:

• make release-pin-conan VERSION=2.4.0
• make release-pin-vcpkg VERSION=2.4.0
• make release-pin-arch VERSION=2.4.0
• make release-pin-homebrew VERSION=2.4.0
• make release-pin-alpine VERSION=2.4.0
• make release-pin-macports VERSION=2.4.0
• make release-pin-spack VERSION=2.4.0
• make release-pin-conda VERSION=2.4.0
• make release-check VERSION=2.4.0

Conan

Local Conan packaging is version-synced by make release, and make release-pin-conan pins the post-tag archive hash used by the recipe.

Use it to verify the shipped recipe still builds:

make package-conan

Current scope:

• local recipe path: packaging/conan/conanfile.py
• local source metadata: packaging/conan/conandata.yml
• local consumer test: packaging/conan/test_package

Current non-scope:

• ConanCenter submission is not automated here yet
• if and when ConanCenter packaging is added, it will need its own source-download metadata and review path

vcpkg

The vcpkg port in this repo is an overlay/custom-registry seed, not an upstream microsoft/vcpkg port checkout.

Release sequence:

make release VERSION=2.4.0
git tag 2.4.0
git push origin main 2.4.0
make release-pin-vcpkg VERSION=2.4.0
make package-vcpkg

What gets updated:

• packaging/vcpkg/icey/vcpkg.json version is synced by make release
• packaging/vcpkg/icey/portfile.cmake archive ref and SHA512 are pinned by make release-pin-vcpkg

Arch / AUR

The Arch packaging in this repo is the AUR seed:

• packaging/arch/PKGBUILD
• packaging/arch/.SRCINFO

Release sequence:

make release VERSION=2.4.0
git tag 2.4.0
git push origin main 2.4.0
make release-pin-arch VERSION=2.4.0
make package-arch

What gets updated:

• pkgver and pkgrel are synced by make release
• the source URL is synced by make release
• the archive SHA256 is pinned by make release-pin-arch

For a real AUR publish, copy the final PKGBUILD and .SRCINFO into the AUR repo after the hash is pinned and the local makepkg run passes.

Homebrew

The Homebrew packaging in this repo is a tap-local seed:

• packaging/homebrew/Formula/libdatachannel.rb
• packaging/homebrew/Formula/icey.rb

Release sequence:

make release VERSION=2.4.0
git tag 2.4.0
git push origin main 2.4.0
make release-pin-homebrew VERSION=2.4.0
brew install --formula ./packaging/homebrew/Formula/libdatachannel.rb
brew install --formula ./packaging/homebrew/Formula/icey.rb

What gets updated:

• version, source URL, and placeholder SHA are synced by make release
• the final release archive SHA256 is pinned by make release-pin-homebrew

The icey formula depends on the tap-local libdatachannel formula because Homebrew core does not currently ship that dependency.

Debian / PPA

The Debian packaging in this repo is a source-package seed intended for Debian-style apt repositories and Launchpad PPAs:

• packaging/debian/debian/control
• packaging/debian/debian/rules
• scripts/package-debian-source.sh

Release sequence:

make release VERSION=2.4.0
make release-check VERSION=2.4.0
make package-debian-source

For a Launchpad target series, set the distribution explicitly:

DEBIAN_DISTRIBUTION=noble make package-debian-source

What gets updated:

• the Debian changelog version is synced by make release
• make package-debian-source stages a full source package under build/package/debian/
• that staging flow vendors the pinned source tarballs needed for a WebRTC-enabled build where distro packages do not exist yet

Release Checklist

• update CHANGELOG.md and ROADMAP.md
• run make release VERSION=x.y.z
• commit the pre-tag release metadata
• create and push the plain semantic-version tag
• run make release-finalize VERSION=x.y.z
• commit the pinned package-manager archive hashes and successful final check
• verify the package-manager entry points you intend to publish
• if you are targeting apt or Launchpad, run make package-debian-source after the version sync
