| 6 | * Non-backwards-compatible changes between libyang version 2 and 3 are rather minor and can be summarized as providing |
| 7 | * structured error information (instead of a single message), unifying **lyd_new_*()** function options, and some |
| 8 | * minor changes such as removing deprecated functions or making a few functions inlined. However, there is another |
| 9 | * large change that has not affected the API, specifically configuration system-ordered lists and leaf-lists are now |
| 10 | * ordered based on their keys/values, respectively. Except for moderately slower performance and negligible increased |
| 11 | * memory requirements, it should not affect existing applications (assuming they do not rely on the previous order of |
| 12 | * these instances). |
| 13 | * |
| 14 | * The complete generated list of changes (without any additional notes) can be found in |
| 15 | * <a href="../compat_report_2_3.html">the compatibility report</a>. |

| 17 | * @section transition2_3Logging Logging |
| 18 | * |
| 19 | * Except for some function adjustments, ::ly_err_item has been changed to provide every piece of error information in a |
| 20 | * separate member to allow for easier processing. |
| 21 | * |
| 22 | * Here is the overview of the changed / removed / added functions connected to logging. |

| 26 | * ly_last_errmsg() | ::ly_last_logmsg() | Function renamed with the same functionality. |
| 27 | * ly_strerrcode() | ::ly_strerr() | Function renamed with the same functionality. |
| 28 | * ly_errcode() | - | Now requires ::ly_err_last() call. |
| 29 | * ly_errmsg() | - | ^ |

| 39 | * lyd_find_xpath3() | ::lyd_find_xpath3() | Optional prefix data parameter added. |
| 40 | * lyd_new_path() | ::lyd_new_path() | All options now in a single bitmap parameter of @ref newvaloptions. |
| 41 | * lyd_new_any() | ::lyd_new_any() | ^ |

| 47 | * lyd_new_term() | ::lyd_new_term() | ^ |
| 48 | * lyd_new_list3_bin() | ::lyd_new_list3() | Functionality now merged into the single function. |
| 49 | * lyd_new_list3_canon() | ^ | ^ |
| 50 | * lyd_new_list_bin() | ::lyd_new_list() | Functionality now merged into the single function. |

| 56 | * @section transition2_3Minor Other Minor Changes |
| 57 | * |
| 58 | * Except for the function changes below, ::lysc_type now has a copy of the typedef name, if applicable. There |
| 59 | * are use-cases when this information is needed even in the compiled schema tree such as checking the real type of |
| 60 | * a union value. |

| 67 | * lyd_find_xpath4() | ::lyd_find_xpath3() | Previous lyd_find_xpath3 was removed to reduce symbols. |
