 # Clixon CHANGELOG
 
 ## 3.3.3 Upcoming
+* Added a format parameter to clicon_rpc_generate_error() and changed error
+  printouts for backend errors, such as commit and validate. Example of the
+  new format:
+
+```
+> commit
+Sep 27 18:11:58: Commit failed. Edit and try again or discard changes:
+protocol invalid-value Missing mandatory variable: type
+```
+
 * If clixon config file has .xml ending, yang/clixon-config.yang is used as
   model for an xml-based configuration file. Otherwise legacy format is used.
+* The clixon config file format has changed. It now uses XML and YANG.
+  Old configuration files work, but you can use the new by setting an .xml suffix.
+ The yang model is yang/clixon-config.yang.
 * netconf client was limited to 8K byte messages. Now limit is 2^32.
 * Added event_poll function.
 * Added experimental xml hash for better performance of large lists.
