But commented out for now, because:

The authorization mechanism you have provided is not supported. Please use
AWS4-HMAC-SHA256
Merge branch 'master' into s3-aws
enable frankfurt

The aws library supports the AWS4-HMAC-SHA256 that it requires.
Merge branch 'master' of ssh://git-annex.branchable.com into s3-aws
