title: Deprecated meaning?
body: <p>When jQuery, Microsoft or some other software company says:"this function is deprecated".</p>
  
  <p>For example, when there is a func1 that works fine in version 1.0 and is deprecated in version 2.0 that also introduces a new func2:</p>
  
  <ol>
  <li>Should func1 also be included in version 2.0 for backwards compatibility?</li>
  <li>Is func1 supposed to work without bugs in version 2.0? ( func2 is fine with versions 2 and 1)</li>
  <li>Is func2 allowed not to work correctly in version 2.0?</li>
  </ol>
  
  <p>What does deprecation really mean and does it mean the same in all organizations?</p>
  
  <p>For ex. the live method in jQuery doesn't work in 1.7 in IE but it does in Chrome).</p>
