This NEWS file for liblingoteach covers a short overview about the 
	latest changes.

0.2.1   2003/11/23:
-------------------
  * ling_conf_set_app_name() and ling_conf_set_lang_file() return NULL on 
    failure instead of NULL or an empty lingConfig
  * In some cases ling_lang_get_languages() produced memory leaks. This has 
    been fixed.
  * In some cases ling_lang_get_max_languages() produced memory leaks. This has 
    been fixed.
  * Some internal lesson functions did not initialize structures correctly.
    This has been fixed.
  * Some internal lesson functions did not clean up all memory references,
    which resulted in high memory usage and possible memory leaks. This has 
    been fixed.
  * In seldom cases ling_lesson_save_lesson() did not close the file correctly,
    which could lead to incorrect saving and buggy file contents. This has 
    been fixed.
  * If meaning ids had negative values, ling_lesson_create_tree() could get mad
    and produce unwanted results. This has been fixed.
  * Missing checks for successful memory allocation in 
    ling_lesson_create_tree() could lead to unwanted results and segmentation 
    faults. This has been fixed.
  * Missing checks could lead to unwated results and segmentation faults 
    due to wrong data passed to libxml2 in ling_meaning_find_sound(). This has
    been fixed.
  * A wrong buffer size could lead to segmentation faults when using 
    ling_meaning_save_lesson(). This has been fixed.
  * ling_meaning_get_by_word_id() could cause a inconsistent memory table in 
    libxml2 due to a missing allocation check. This has been fixed.
  * ling_meaning_save_meanings() returned TRUE, disregarding if the lesson
    could be saved to a file or not. This has been fixed.
  * ling_meaning_get_new() will now initialize all members with NULL or 0.
  * ling_lang_get_languages will now return -1 on failure
  * New function ling_lang_free_languages for freeing language arrays created
    by ling_lang_get_languages.
  * ling_lesson_return_rand_lesson() can spin in an endless loop due to a 
    wrong check. This is fixed. It now returns NULL if nothing can be found
    within twenty loop rounds.
  * Meanings now support additional descriptions.
    
    Thanks to Dag Bakke and others for reporting errors.

0.2.0	2003/10/12:
-------------------
  * Types have been changed to work as linked lists (lingMeaning).
  * A new type lingLesson for lesson lists has been introduced.
  * all global variables, except the defines for XPath-validation have been
    removed. The library can now be used by multiple programs at the same time.
  * Meaning lists can now easily be modified using different manipulation
    interfaces like edit, add and remove.
  * A new type lingConfig is introduced on a per lesson base.
  * The library now handles application names for all lessons.
  * All interfaces have changed.
