- Introduces internal v3 chunk format support, allowing Loki 2.0.1 to read v3 chunks written by future releases
- Provides a rollback safety net for users who skip directly to a version that writes v3 chunks, enabling them to revert to 2.0.1 and retain compatibility
- No functional changes for upgrades from 2.0.0; the release is optional and primarily for compatibility
