Here are changes:
- IPv6 support support added for FTP.
- CRC32 and MD5 checksum added for FTP.
- "chunkmode=onflyrange" support added for HTTP PUT.
- "preemptiveauth" regular parameter added.
- "cookiesource" extra parameter added to load cookies from Java Plugin.
- "resumeheader" extra parameter added to improve resume support.
- i18n.properties improved:
progress.bar.upload.checksum.failed.label

Could you please elaborate a bit on the new "resumeheader" parameter?

You can now define HTTP header for resume support. Default is "size" which includes file size info on remote folder. You can now customize it and use "Content-Length" if you need. Some customers prefers relying on "Content-Length" returned by HTTP HEAD request. Does it make sense?
