* These were included for testing
* If you want to run the Clixon test suite you need to point `YANGMODELS`, see test/README.md
* The following configure options have been removed:
* `configure --with-opt-yang-installdir=DIR`
* `configure --enable-optyangs`
* You may need to specify standard YANGs using configure option `--with-yang-standard-dir=DIR`
* Updated yang ietf models with fetures for tet
* Added option `CLICON_YANG_AUGMENT_ACCEPT_BROKEN` to accept broken yangmodels.
* This is a debug option for CI testcases where standard YANG models are broken
* Fixed: [very slow execution of load_set_file #288](https://github.com/clicon/clixon/issues/288)
* New `clixon-lib@2021-11-11.yang` revision
* Modified option: RPC stats extended with YANG stats
* Modified `clixon-config@2021-11-11.yang` revision
* Added option:
* CLICON_PLUGIN_CALLBACK_CHECK
* Enable to make plugin context check before and after all callbacks.
* Added statistics for YANG: number of objects and memory used
* Use the treeref no-copy option of CLIgen to reduce memory
* Refactored cli-generation/autocli-start code
* Refactored cligen glue functions to use cligen_eval directly (remove clicon_eval,clixon_cligen_eval)
* Added ancestor config cache indicating wether the node or an ancestor is config false or true
* Improved yang cardinality lookup
* Added yang_init(), called from all apps using yang
