# Clixon Changelog
## 4.3.0 (Expected: December 2019)
### Minor changes
* Added "canonical" global namespace context: `nsctx_global`
* This is a normalized XML prefix:namespace pair vector computed from all loaded Yang modules. Useful when writing XML and XPATH expressions in callbacks.
* Get it with `clicon_nsctx_global_get(h)`
* Added wildcard `*` as a mode to `CLICON_MODE` in clispec files
* If you set "CLICON_MODE="*";" in a clispec file it means that syntax will appear in all CLI spec modes.
* State callbacks provided by user are validated. If they are invalid an internal error is returned.
* Fixed multi-namespace for augmented state which was not covered in 4.2.0.
### API changes on existing features (you may need to change your code)
* Yang files reorganized into three classes: clixon, mandatory, optional (previous "standard" split into mandatory and optional).
* Clixon and mandatory yang spec are always installed
* Optional yang files are loaded only if configured with `--enable-optyangs` (flipped logic and changed from `disable-stdyangs`). NOTE: you must do this to run examples and tests.
* Optional yang files can be installed in a separate dir with `--with-opt-yang-installdir=DIR` (renamed from `with-std-yang-installdir`)
* C-API
* Added namespace-context parameter `nsc` to `xpath_first` and `xpath_vec`, (`xpath_vec_nsc` and xpath_first_nsc` are removed).
* Added clicon_handle as parameter to all `clicon_connect_` functions to get better error message
* Added nsc parameter to `xmldb_get()`
* The multi-namespace augment state may rearrange the XML namespace attributes.
* Main example yang changed to incorporate augmented state, new revision is 2019-11-15.
### Corrected Bugs
* [filter in netconf - one specific entry #100](https://github.com/clicon/clixon/issues/100)
* [xpath_tree2cbuf() changes integers into floating point representations #99](https://github.com/clicon/clixon/issues/99)
* [xml_parse_string() is slow for a long XML string #96](https://github.com/clicon/clixon/issues/96)
