I did not update my iPad 3 with the last update, will that affect me updating to IOS 6?

I did not update my iPad 3 with the last update, will that affect me updating to the new IOS 6? Will I get all the updates I missed in the previous update if I update to IOS 6. If not, tell me where to go to get the last update before I update to IOS 6. I thought I had time before this new one came out. Thanks for any help I get.
