 ### API changes on existing features (you may need to change your code)
+* New clixon-config@2020-02-22.yang revision
+  * Added search index extension
 * JSON parse error messages change from ` on line x: syntax error,..` to `json_parse: line x: syntax error`
 * Unknown-element error message is more descriptive, eg from `namespace is: urn:example:clixon` to: `Failed to find YANG spec of XML node: x with parent: xp in namespace urn:example:clixon`.
 * C-API parse and validation API more capable

 ### Minor changes
 
-* C-API: Added instrumentation: `xml_size` and `xml_stats_get`.
+* C-API: Added instrumentation: `xml_stats` and `xml_stats_global`.
 * Obsoleted and removed XMLDB format "tree". This function did not work. Only xml and json allowed.
 * Test framework
   * Added `-- -S <file>` command-line to main example to be able to return any state to main example.
