 ### API changes on existing protocol/config features (You may have have to change how you use Clixon)
 
+* xml-stats moved from clixon-config.yang as state data to an rpc `datastats`in clixon-lib.yang 
 * Stricter incoming RPC sanity checking, error messages may have changed.
 
 ### C-API changes on existing features (you may need to change your plugin C-code)
 
+* Two new plugin callbacks added
+  * ca_daemon: Called just after a server has "daemonized", ie put in background.
+  * ca_trans_commit_done: Called when all plugin commits have been done.
 * Length of xml vector in many structs changed from `size_t` to `int`since it is a vector size, not byte size. This includes `transaction_data_t`
 * `xml_merge()` changed to use 3-value return: 1:OK, 0:Yang failed, -1: Error
 * `clixon_netconf_error(category, xerr, msg, arg)` removed first argument -> `clixon_netconf_error(xerr, msg, arg)`
