title: Use of @since in PHP code
body: <p>I am using the @since comment in my PHP code. I have a question about its use though. Say I have a function that performs a particular task, and it's been implemented in version 1.0.</p>
  
  <p>So I currently have @since 1.0.</p>
  
  <p>Now I go ahead and change the function's name, although the code inside remains the same. 
  Should it now say @since 3.0 (the current version) or remain @since 1.0?</p>
