@ -20,11 +20,11 @@ Expected: January 2025
* New: [feature request: support xpath functions for strings](https://github.com/clicon/clixon/issues/556)
* Added: re-match, substring, string, string-length, translate, substring-before, substring-after, starts-with
* Added support for system-only-config data
* A mechanism to not store sensitive data in the datastore, instead use application callbacks to store the data in system state.
* Store sensitive data in the "system" instead of in datastores
* New `CLICON_XMLDB_SYSTEM_ONLY_CONFIG` configuration option
* New `system-only-config` extension
* New `ca_system_only` backend callback for reading system-only data
* New `clixon-config@2024-08-01.yang` revision
* New `clixon-config@2024-11-01.yang` revision
* Added: `CLICON_XMLDB_SYSTEM_ONLY_CONFIG`

"If set, some fields in the configuration tree are not stored to datastore.
Instead, the application must provide a mechanism to save the system-only-config
Instead, the application provides a mechanism to save the system-only-config
in the system via commit/system-only-config callbacks.
Specifically, system-only data is read from the system except in the following case:
datastore is candidate, and either locked or modified
In that case, the system-only config is stored in the cache (not in file) and
not read from the system.
The system-only data is still not stored in the datastore however.
See also extension system-only-config in clixon-lib.yang";
