• I added CHANGELOG entry for this change.
• Change is not relevant to the end user.

Changes

• Split the function VerifyRepair in two dedicated functions verify and repair.
• Replace return statement by continue to go to the next iteration. This allow to parse all blocks from a bucket.
• Added a log in debug level to just say when a block has no issue :
