Yes you can upgrade from older versions, upgrading from the latest 0.6.x to 0.7.0 will be pretty straightforward.
Strategy to clean upload files is required
Upload files still exist even when we delete all posts using it, and wasting disk space if there's too many files.I think a command line API should be given at least.

i agree too, the files exists too much, and many files are not used any more.
There is a report that shows abandoned files. You can delete them manually. A bit of a pain, but there is little other way to be sure that something isn't needed.
