Clixon 4.4 three compile-time options: MOVE_TRANS_END for changing transaction-end callbacks; STATE_ORDERED_BY_SYSTEM to make state data system ordered; XML_MERGE_TWO_ROUNDS to improve xml_merge performance.

 ### API changes on existing protocol/config features
+* State data is now ordered-by system for performance reasons. For example, alphabetically for strings and numeric for integers
+  * Controlled by compile-time option `STATE_ORDERED_BY_SYSTEM`
 * Obsolete configuration options present in clixon configuration file will cause clixon application to exit at startup. 
 * JSON
   * Empty values in JSON has changed to comply to RFC 7951

 ### Minor changes
 
+* Added a compile-time option `MOVE_TRANS_END` which changes the semantics of the transaction_end callback. Instead of being called after a transaction, it is called prior to the target database is installed. This is to ensure that the source and target databases are same as for other transaction callbacks.
+
 * Moved hello example to [clixon-examples](https://github.com/clicon/clixon-examples)
 * Sanity check of mandatory key statement for Yang LISTs.
   * If fails, exit with error message, eg: `Yang error: Sanity check failed: LIST vsDataContainer lacks key statement which MUST be present (See RFC 7950 Sec 7.8.2)`
