+Gosub changes
+-------------
+ * A new function, STACK_PEEK, has been added, to correlate for functionality
+ available in AEL in 1.4 that disappeared in 10. STACK_PEEK permits the
+ user to see the location of the calling Gosub from within the subroutine.

===========================================================
+From 10.3 to 10.4:
+
+* 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 10, 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 10.2 to 10.3:
* If no transport is specified in sip.conf, transport will default to UDP.
