Versioning Lifecycle Policy

To provide clarity on support and upgrade paths, Fusion now follows a Versioning Lifecycle Policy:

• Latest Supported Version (LSV): The most recent release and the previous three versions receive full support.

• Oldest Supported Version (OSV): The minimum supported version continues to receive limited support.

• End-of-Life (EOL): Versions older than the OSV are no longer supported and require an upgrade.

This policy ensures flexibility while maintaining stability and security across all supported versions.
