title: iPhone app Update Vs new version
body: <p>Let's say I have an existing IOS app live on Appstore which is version 1.0</p>
  
  <p>Now I make some changes to the app and want to submit back.</p>
  
  <p>Are there 2 separate ways to submit ?
  Like can I still keep the version as 1.0 and just submit the app OR
  I need to create a new version 1.1 and then submit it ?</p>
  
  <p>What are the differences in the process?</p>
  
  <p>Also from the customer end, how does this work for new/existing users ?</p>
