I downloaded Version 0.7.0.3082

Stitched a couple of Cylindrical Panos with no problems.
And that's amazing considering all the trouble I had
getting Hugin to run on my machine in the past.

I had to use your special version of enblend_HDR compiled
without GPU support to get 0.7 beta 4 to run.

But this version ran fine on my machine.  I give it a passing
grade.

Suggestion: When you select the output file type (TIFF, JPG, etc.)
the dialog box that pops up asking for the location and name to
save the panorama in/as should have the file type as the "Save as type:"
default entry.

Also, the "Specify output prefix" dialog stays up through the stitching process.
Shouldn't it pop down?  I accidentally hit the "Create Panorama" button twice and
got a second "Specify output prefix" dialog.  I think I could have started
another stitch at that time.  That would not be a good thing on my
puny machine.  Maybe an option that allows/disallows multiple stitches would
be useful.  Some machines are big and powerful enough to do multiple,
simultaneous stitches but mine isn't.

I don't know if Hugin is designed to support multiple stitches.

Also, I miss the option to have the final output shown in my favorite
image editor.  That was useful.  Maybe I'm just not seeing that option.
Does it still exist?

My needs are modest but all said I'd say that you've done good work.
Haven't tried the control point editor yet.  Nor have I tried to
stitch a spherical pano.  But I think this release is a keeper.
