Origen Metal Release Notes#

Origen Metal 1.5.1#

This release modernizes the O2 development, documentation, CI, and release stack and improves program-generation exception handling.

Migrated the workspace from Poetry to UV, including committed lockfiles, assisted application migration, rollback protection, and compatibility handling across supported Python versions.
Added migration commands that preview and convert existing Poetry applications while preserving the original files if validation fails.
Modernized the documentation stack with current Sphinx, MyST, and PyData tooling, refreshed authored documentation, and improved local web development with build, watch, serve, and live-reload support.
Added coordinated Origen and Origen Metal releases with atomic version and history updates, exact-reference publication workflows, package verification, resumable releases, and website deployment only after all selected products publish successfully.
Updated the Rust workspace and command-line infrastructure, including the Clap migration and stricter command validation.
Improved CI performance and coverage with caching, superseded-run cancellation, lockfile validation, wheel ABI verification, and Linux and Windows package checks.
Preserved Python 3.7 support by handling the UV Windows launcher incompatibility while keeping dependency resolution sourced from the committed lockfile.
Fixed program-generation context cleanup when exceptions occur inside Group, Condition, or Resources blocks. The original exception now propagates without leaving child AST nodes open or being replaced by a secondary closure error. Contributed by Stephen in #238.

Added typed class and list test-program parameters and completed the associated Origen Metal release updates.
