I don't have the middle two releases (nor do I need them). I downloaded all the games at the beginning of the comp. Yours was release 1. Then I saw that there were a few updates from you blog entries, so I downloaded the latest and saw that it was still release 1. This could be confusing if, for example, IFDB said the latest version was release 1 and you've got release 1, so you think it's up-to-date, but it's actually got some bugs that have been fixed in a later release 1.
Good point ... yeah, release numbers fall into an odd gap for me. I like being able to have point releases, so I think of those as 1.0.1, 1.1, etc., which I round down to 1.
That's how it is in a full development environment, but it doesn't need to be the case here. There's a part of me that feels a 2.0 release for fixing a minor bug is overpromising, but I think it's good to differentiate the latest release from the initial release, and since Inform doesn't allow point-releases, I might as well make it release 2.
So it seems like a reasonable compromise for the future is to have release 2 be any in-comp changes since release 1, then release 3 be a quick turnaround for post-comp features with additional content.
