Breaking changes

This page is the audit trail of every breaking change shipped in a stable release. The 0.1.0-preview track is still pre-stable, so changes within preview minors are not listed here — they’re tracked in the release notes.

How to use this page

1. Find the release where the change shipped.
2. Read the before snippet — the API you’re using today.
3. Compare against after — the new shape.
4. Apply the diff to your code; the composition smoke tests will catch anything you miss.

0.1.0-preview

The initial preview track. No backwards-compatibility commitment yet.

0.2.0-preview (planned)

Specific breaking changes will land here as they are committed. Each entry will have:

• What changed — one-sentence summary.
• Before — code snippet at 0.1.0-preview.
• After — code snippet at 0.2.0-preview.
• Why — the rationale.
• Mechanical migration — whether Cephalon.MigrationAssistant can rewrite it.

Future stable releases

Once CephalonEngine ships 1.0.0, this page becomes the contract for every breaking change going forward. Stable releases follow strict semver — breaking changes only land in major bumps.
