It appears that Adobe has lost the 1.11 updater when they acquired Macromedia. The only updater file available on their website is 1.1. Because they appear to have lost it, they're trying to remove references to 1.11 from their site too.

Also, the 1.1 version still has security issues as per the following links that were addressed in 1.11:
