Origen 2 Release Notes#

Origen 2.0.0.dev9#

  • Released: 2026-08-26

  • Author: Priyavadan Kumar

  • Tag: origen-v2.0.0.dev9

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  • Improved CI performance and coverage with caching, superseded-run cancellation, lockfile validation, wheel ABI verification, and Linux and Windows package checks.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.
