+Gosub changes
+-------------
+ * A new function, STACK_PEEK, has been added, to correlate for functionality
+ available in AEL in 1.4 that disappeared in 1.8. STACK_PEEK permits the
+ user to see the location of the calling Gosub from within the subroutine.

===========================================================
+From 1.8.11 to 1.8.12:
+* In AEL dialplans, the "h" extension will now be inherited from prior
+ calling contexts, just as it had in 1.4. If you have created an AEL
+ dialplan from scratch in earlier versions of 1.8, you may want to
+ check that the execution of "h" extensions in earlier contexts is what
+ you want. If you want to interrupt this functionality, simply placing
+ an "h" extension in the macro where you want no inheritance to take
+ place should be sufficient.
+
From 1.8.10 to 1.8.11:
* If no transport is specified in sip.conf, transport will default to UDP.
