⚠️ Potential issue | 🟡 Minor | ⚡ Quick win

Clarify version discrepancy between PR description and actual change.

The PR description mentions updating to v1.1.2 (with only build/wheel updates), but the actual change updates to v1.2.0. This inconsistency should be clarified—if v1.2.0 is intended, the PR description should be updated to reflect the correct version and include any relevant v1.2.0 release notes or breaking changes.
