## プロジェクトの歴史と使われ方

Breezy, invoked as brz, is a decentralized revision-control system and a friendly fork of Bazaar. It preserves Bazaar disk-format and protocol compatibility while running on Python 3 and adding native support for both Bazaar and Git file formats.

### プロジェクトの歴史

The official README states that Breezy is a friendly fork of Bazaar, whose original project was hosted on Launchpad. It explicitly names Python 3 support as a key difference from Bazaar's Python 2 codebase.

The GitHub repository was created in May 2018, while the official documentation footer credits Breezy Developers from 2017-2018. That places the fork in the period when many Python projects were moving away from Python 2 and legacy Bazaar users still needed a maintained path.

Breezy kept the bzr command available while introducing brz, and its input package facts list executables for brz, bzr, Git remote helpers, and Bazaar smart-server helpers. That continuity is central to its history: it is both a successor and a compatibility bridge.

### 採用の歴史

The input package facts show unusually broad package-manager coverage for a non-Git VCS: Alpine, Homebrew, Chocolatey, Debian, Fedora, MacPorts, Nix, Arch, and Ubuntu all carry Breezy or Bazaar-compatible packaging names.

Breezy's adoption comes from two overlapping audiences: existing Bazaar users who needed maintained tooling, and developers who wanted Bazaar's workflow with Git interoperability. Its official docs also link Launchpad support, Bazaar mailing-list continuity, and Breezy-specific Matrix support.

### 使われ方

The README describes Breezy as supporting both centralized workflows like CVS/Subversion and distributed workflows like Git/Mercurial, including checkouts, feature branches, and shared working trees.

The documentation set includes a user guide, tutorials, quick reference, release notes, upgrade guide, user reference, admin guide, migration docs, and plugin docs. The upgrade guide covers checking, reconciling, and upgrading branch formats, especially for larger communities and Launchpad-hosted branches.

Configuration and authentication are documented in Breezy's user reference. The curated paths for breezy.conf, locations.conf, branch.conf, and authentication.conf match that role as a full VCS with local, per-location, per-branch, and credential configuration.

### パッケージ好きにとっての重要性

Breezy is significant because it is the maintained package-manager path for Bazaar-era version-control workflows. It keeps old branch formats and protocols usable while making the tool viable on Python 3.

It also matters as a rare bridge VCS package: it is neither simply Git nor simply Bazaar. Package maintainers have to account for compatibility executables, Git helpers, Python dependencies, and distro naming differences such as brz versus bzr.

For history-minded users, Breezy shows how package ecosystems preserve tooling after a dominant upstream fades. A fork can become the practical continuation when distributions, users, and hosted services still depend on old formats.

### タイムライン

- 2017: Official documentation credits Breezy Developers beginning in 2017.
- 2018-05: The Breezy GitHub repository was created.
- 2018: The README identifies Breezy as a Python 3 friendly fork of Bazaar.
- 2020: Breezy 3.x documentation and release notes became the main user-facing documentation set.
- 2026: Official repository metadata showed active development continuing.

### Related projects

- Bazaar is the direct predecessor and compatibility target named by the Breezy README.
- Git is a supported file format and interoperability target named by the README.
- Launchpad remains part of Breezy's support and migration story through docs, answers, bugs, and historical Bazaar hosting.
