-===== New in Old Modules =====
 ===== New in Core =====
+  * new module exports interface
+    * unified from Kamailio and SER module exports interfaces
+  * locking - added api functions for recursive lock sets
+  * added xflags field to sip_msg_t - holds extended flags - 64 new flags in addition to the old 32 flags
+  * new internal msg flag to add srvid param to local via
+  * added internal flag for adding xavp fields to via params
+  * parser - assign ids for more methods
+    * KDMQ and HTTP method types GET, POST, PUT and DELETE
+  * pv - default number of buffer slots set to 40
+  * new rpc command - core.ppdefines_full
+    * print preprocess defines with their details
+  * xavp - extended to hold a bare void pointer value
+    * useful to link data that doesn't need cloning or freeing
+  * added config defines for application version
+    * three tokens are defined for version X.Y.Z: KAMAILIO_X, KAMAILIO_X_Y, KAMAILIO_X_Y_Z
 ==== Interpreter ====
+  * kemi - more core functions exported to kemi framework
+  * kemi - added KSR.is_method_in("mflags")
+    * check if current method matches one listed in the flags
+    * flags are: I (INVITE), A (ACK), B (BYE), C (CANCEL), R (REGISTER),
+      P (PUBLISH), S (SUBSCRIBE), N (NOTIFY), O (OPTIONS)
+    * KSR.is_method_in("IABC")
+  * kemi - renamed KSR.drop() to KSR.set_drop()
 ==== Parameters ====
+  * new parameters to control the size of pv cache
+    * pv_cache_limit - the limit how many pv declarations in the cache after which an action is taken. Default value is 2048
+    * pv_cache_action - specify what action to be done when the size of pv cache is exceeded. If 0, print an warning log message when the limit is exceeded. If 1, warning log messages is printed and the cache systems tries to drop a $sht(...) declaration. Default is 0
+  * aliased global param ip_free_bind to ip_nonlocal_bind - match better with linux system control option
+  * new parameter kemi.onsend_route_callback
+    * allow setting the name of the function to be called by kemi framework as equivalent of onsend_route {}
+    * default value: ksr_onsend_route
+    * set to empty string or "none" to skip the execution of this kemi callback
+  * new parameter kemi.reply_route_callback
+    * set the name of kemi callback function to be executed on receiving a sip reply (equivalent of reply_route)
+    * default: ksr_reply_route
+    * set to empty or "none" to skip execution of this callback
+  * new parameter route_locks_size
+    * if set, kamailio creates a group of recursive locks used to sync on execution of request_route and reply_route based on hashing ID of Call-ID header. In other words, if a message has triggered the execution of request_route or reply_route, any other message with the same Call-ID     waits until the other one finishes the execution.
+  * new parameter kemi.event_route_callback
+    * set the name of kemi function to be executed for core event route equivalent
+    * default value is not set (no callback function name). If set to "none", it is also not executed.
+    * callback function receives a string parameter with the name of the event
+    * execute kemi event callback for "core:worker-one-init"
+  * new core parameter xavp_via_params
+    * set the name of the xavp whose subfields will be added as via params
 ==== Functions ====
+  * core functions exported to kemi interface
