### Known issues
### Major changes:
* Clixon can now be compiled and run on Apple Darwin.
-
* Performance improvements
* Added xml hash lookup instead of linear search for better performance of large lists. To disable, undefine XML_CHILD_HASH in clixon_custom.h
* netconf client was limited to 8K byte messages. Now limit is 2^32 bytes

Backward compatibility is enabled by defining BACKEND_STARTUP_BACKWARD_COMPAT in include/clixon_custom.h
### Minor changes:
+* When user callbacks p_statedata() or rpc callback call returns -1, clixon_backend nolonger silently exits. Instead a log is printed and an RPC error is returned.
+
* Disabled key-value datastore. Enable with --with-keyvalue
* Removed mandatory requirements for BACKEND, NETCONF, RESTCONF and CLI dirs.
* When user callbacks such as statedata() call returns -1, clixon_backend no
