### API changes on existing protocol/config features
|
||||||
|
|
||||||
|
Users may have to change how they access the system
|
||||||
|
|
||||||
|
* With-defaults default retrieval mode has changed from `REPORT-ALL` to `EXPLICIT`
|
||||||
|
* This means that all get operations without `with-defaults` parameter do no longer
|
||||||
|
return implicit default values, only explicitly set values.
|
||||||
|
* Applies to NETCONF `<get>`, `<get-config>` and RESTCONF `GET`
|
||||||
|
* To keep backward-compatible behavior, define option `NETCONF_DEFAULT_RETRIEVAL_REPORT_ALL` in
|
||||||
|
include/clixon_custom.h
|
||||||
|
* Alternatively, change all get operation to include with-defaults parameter `report-all`
