NSIS and new RAR5 archive format support?

Hi,

Quick Question:

WinRAR release version 5.0 with new RAR5 compression format. Will I be able to use it in you software as default method for compression/decompression ? I would like to use RAR5 format because from what I read and tested it has 95% of maximum possible 7z ULTRA compression ration, but the decompression of RAR5 format is over 2-4 times faster than 7z. Does NSIS can create non-msi (just simple exe installer) that can use RAR5 format ?

rar is a proprietary compression format

So? I own a full legit copy of it. My question is: will I be able to create NSIS installer and put "unrar.dll" into it and be able to unpack such installer?

You will never see native RAR support because the format is closed, if you want to call some 3rd-party dll then you would have to use the system plugin or if the API is complex it might be better to write a custom plugin...
