**Not Yet Scheduled:**

- Monitor v1.0-beta.1 for issues (2 weeks minimum)
- Address any discovered problems
- Remove legacy scripts (v2.0.0)
- Remove deprecation warnings
- Final validation and testing
- Tag release v2.0.0

**Current Phase 5 Prepares For:**

- Clear migration path for users
- Documented deprecation timeline
