*
|
|
* [TOC]
|
|
*
|
|
* Non-backwards-compatible changes between libyang version 2 and 3 are rather minor and can be summarized as providing
|
|
* structured error information (instead of a single message), unifying **lyd_new_*()** function options, and some
|
|
* minor changes such as removing deprecated functions or making a few functions inlined. However, there is another
|
|
* large change that has not affected the API, specifically configuration system-ordered lists and leaf-lists are now
|
|
* ordered based on their keys/values, respectively. Except for moderately slower performance and negligible increased
|
|
* memory requirements, it should not affect existing applications (assuming they do not rely on the previous order of
|
|
* these instances).
|
|
*
|
|
* The complete generated list of changes (without any additional notes) can be found in
|
|
* <a href="../compat_report_2_3.html">the compatibility report</a>.

|
* @section transition2_3Logging Logging
|
|
*
|
|
* Except for some function adjustments, ::ly_err_item has been changed to provide every piece of error information in a
|
|
* separate member to allow for easier processing.
|
|
*
|
|
* Here is the overview of the changed / removed / added functions connected to logging.

* Except for the function changes below, ::lysc_type now has a copy of the typedef name, if applicable. There
