New PUT option -nobucketlisting:this option forces S3Express not to list the remote S3 bucket. Instead of listing the remote S3 bucket before the put operation starts, S3Express will check file by file if a local file needs to be uploaded. This option can be quite slow, but it is faster when a few files are to be uploaded to a large S3 bucket that already has lot of files in it.
New global option -disablecertvalidation (advanced): disable SSL certificate validation over https.
Restored support for S3 buckets with periods '.' in the name (over the https protocol).
Fixed an issue that could occur when using the new PUT option -optimize with the option -mul.
