• static build support
• loads of minor or major bugfixes and enhancements

version 0.14 - release 1

Main features of this release are:

• XPath evaluation optimized
• C++ bindings updated
• new function ly_path_data2schema() for transforming data paths to schema paths
• large number of bugfixes and minor enhancements

version 0.13 - release 2

There are no API/ABI differences with the previous release.

Main features of this release are:

• large number of bugfixes
  • mostly corner cases and complex YANG statement bugs

version 0.13 - release 1

The complete API/ABI diff to the previous release is available at netopeer.liberouter.org.

Main features of this release are:

• yanglint enhancements
  • parsing and validating of RPCs, RPC replies, and notifications
  • processing input files customization
• large number of bugfixes
  • most notably augment and leafref (x)path fixed according to RPC
  • this change also included modified path arguments of several API functions (lys_find_path, lyd_find_path)

version 0.12 - release 2

The main features of this release are:

• various bugfixes
• ly_ctx_new_ylpath() and ly_ctx_new_ylmem() to create context according to yang-library data (reflected in yanglint(1))
• allow multiple search paths for the context (reflected in yanglint(1))
• shorthand cases in choice are now implicitly created in schema trees
• default values are not checked in grouping but when the grouping is instantiated
• extended checking of all XPATH expressions
• added pointer to private data in extension instances structures
• number of internal schemas in the context is available in API as LY_INTERNAL_MODULE_COUNT
• strict option in yanglint(1) non-interactive mode

version 0.12 - release 1

The complete API/ABI diff to the previous release is available at netopeer.liberouter.org.

The main features of this release are:

• various bugfixes
• support for YANG extensions (libyang's schema tree structures changed)
• ietf-metadata implemented - support for annotations represented in data as data nodes' attributes
• added possibility to set all the imported modules as implemented
• YANG parser's error messages extended by the path of the invalid node
• nodes, used in must and when XPath expressions, which are not found in schema are reported as warnings, not errors - refering non-exiting nodes is generally allowed despite it is useless

version 0.11 - release 2

The main features of this release are:

• various bugfixes
• include subdirectories of search path when looking for the imported modules and included submodules
• NACM extension instances are not printed in schemas - this is a temporary change until the full support of YANG extensions is implemented
• corrected parsing of backslash-ed characters in YANG strings (even in YANG 1.0 modules, the clarification from 1.1 is applied)
• changed return code of lys_features_enable() and lys_features_disable() when the feature is already in the desired state
• improved printing of canonical data values
• improved printing of anydata/anyxml trees
