Why the Adobe reader 9 can not skip to 11, and I see adobe 9.5.5 is more recent and FINAL release, so that if this final version has security hole, you won't fix it? Thank you!

I want to improve my adobe 9 to 11, but why it cannot be upgraded directly, the second question is since adobe 9.5.5 is more recent and FINAL output, so if this final release has security hole, adobe will not solve it? Thank you very much!

You are right. This isn't how it's done.  Upgrades are usually in this way, complete news, not a change to the existing product.
