I am using Xara Designer Pro X11. When I open it up, it tells me that there is a new upgrade to Xara Designer Pro X for $99 only until September 27th.
This naming convention has me confused. Is this an upgrade or an older version of what I have?

Then I ran across this HumbleBundle Deal (https://www.humblebundle.com/softwar...n=tile_index_4)

Is this the full blown Xara Designer Pro X? Again does Pro X precede Pro X11? Which is actually the latest version?
