Right. But if it's the only bug... However, the cmd scripts show 11.4, so you'll also have the correct version logged. I don't know whether this is worth a quick new release.
Well, you could just change the version number in the AutoIt scripts to 11.4, recompile them and reupload them. I don't think this mistake justifies a higher version number because it doesn't change anything relevant. I did something similar with one of my Total Commander plugins, just changed the embedded resources and reuploaded the file without increasing the version (because the functionality itself remained the same).
For WOU, the trunk number would increase, nonetheless.
