Please don't top-post, like I asked you.  If you don't know what
top-posting is, Google will explain it to you with the first hit.

It doesn't matter if you made changes or not.  You have to give your

When will you be releasing that version?  And what's keeping you from
changing your website now?

AFAICT, yes.


P.S.: I'm not sure if you are subscribed to ffmpeg-devel, so I CCed you
just in case.  Please keep ffmpeg-devel in the CC as well.
