 # ESAPI Deprecation Policy
 Unless we unintentionally screw-up, our intent is to keep classes, methods, and/or fields whihc have been annotated as "@deprecated" for a minimum of two (2) years or until the next major release number (e.g., 3.x as of now), which ever comes first, before we remove them.
 Note that this policy does not apply to classes under the **org.owasp.esapi.reference** package. You are not expected to be using such classes directly in your code.
