Constant EARLIEST_SUPPORTED_VERSION

Source 
pub const EARLIEST_SUPPORTED_VERSION: Version;
Expand description

The earliest supported version of the on-disk filesystem format.

When a breaking change is made:

  1. LATEST_VERSION should have it’s major component increased (see above).
  2. EARLIEST_SUPPORTED_VERSION should be set to the new LATEST_VERSION.
  3. The SuperBlockHeader version (below) should also be set to the new LATEST_VERSION.

Also check the constant version numbers above for any code cleanup that can happen.
