A public quarterly-granularity roadmap is a Phase 2 deliverable. Until it lands, the most accurate signal of upcoming work is the open issues and the CHANGELOG.

What you can rely on today.

• The stability commitments — MSRV, semver, deprecation windows.
• Solver behavior in any released version: covered by the numerical-correctness suite documented in the book's Numerical Correctness chapter.
• The license: free for non-commercial academic and research use; commercial use requires a separate license. See /license.
