Information for Upgrading From Previous Asterisk Releases
=========================================================

Manager:

* The CallerID fields across Manager events have now been made more
  consistent. CallerID Number will be sent as CallerIDNum and CallerID
  Name will be sent as CallerIDName wherever used.

AEL:

* Macros are now implemented underneath with the Gosub() application.
  Heaven Help You if you wrote code depending on any aspect of this!
  Previous to 1.6, macros were implemented with the Macro() app, which
  provided a nice feature of auto-returning. The compiler will do its
  best to insert a Return() app call at the end of your macro if you did
  not include it, but really, you should make sure that all execution
  paths within your macros end in "return;".
