NOTE: NO BACKWARD COMPATIBILITY IS GUARANTEED FOR 0.x RELEASES !!

release 0.18 (NOT RELEASED YET):

 - The library should now be portable, i.e it should work on any POSIX system.
   On systems lacking glibc, libiconv is needed (see README).

 - New features (see documentation):
     - callback interface:
        - functions to manipulate cross-references (add, delete, link and
          unlink)
        - support for writing Gedcom files
        - complete concatenated text (e.g. for notes) is now passed in the
          end callback
     - C object model interface:
        - functions for string retrieval and modification
        - support for writing Gedcom files
     - development support:
        - m4 macro that can be used in configure.in

 - INTERFACE CHANGE: the end record callback function now takes an extra
   argument: a Gedcom_val, which contains in the case of a REC_NOTE the
   complete concatenated string.

 - The return value of gedcom_init() has changed from void to int to be able
   to return a status, but this should not impact any programs.

 - Various bugfixes.

release 0.17 (12 September 2002):

 - New features (see documentation):
     - new function gedcom_get_by_xref
     - age values are parsed
     - gedcom object model in C

 - INTERFACE CHANGE: the callback functions now take an extra argument: the
   record/element identifier (that is also used as first argument in the
   *_subscribe_* functions).  The extra argument is the first argument.

 - INTERFACE CHANGE: Age values are now parsed: an extra type is added to
   the types possible in a Gedcom_val: an age_value (see documentation for
   details).  So, instead of GEDCOM_STRING, you now need to use GEDCOM_AGE
   for age values.
   As a quick change, you can use the raw_value instead of the parsed_value
   until you make the real change of using the struct age_value.

 - INTERFACE CHANGE: The type of an xref_value can also be XREF_ANY, if
   the actual type is not known yet.  This is e.g. used in the case of an
   association (ASSO): the cross-reference can be any object type, the
   actual type is given by the TYPE subtag.

release 0.16 (16 August 2002):

 - Another bugfixing release.

 - Some compatibility with Lifelines 3.0.2 is added (not necessarily complete).

release 0.15 (27 March 2002):

 - Again mainly a bugfixing release

 - Compatibility with ftree is added, all GEDCOM files written by ftree
   should load fine now.

 - Note for developers: you now have to call the function gedcom_init()
   as soon as possible in your program (before any character set handling
   is done, see documentation for details).  If the function has not been
   called, gedcom_parse_file() will return an error.

release 0.14 (20 January 2002):

 - This is mainly a bugfixing release, no extra features have been added.

 - Some example code is available on how to convert from UTF-8 to the locale
   system, and how to check the library version via configure.in (see the
   documentation for details).

release 0.13 (5 January 2002):

 - Cross-references are now parsed and checked.  For this, an extra type is
   added to the types possible in a Gedcom_val: an xref pointer. This means
   that GEDCOM_XREF_PTR has to be used now in some places instead of
   GEDCOM_STRING.
   A quick change is to replace
     GEDCOM_STRING(val)
   by
     GEDCOM_XREF_PTR(val)->string
   where applicable.  But you can also store an object in the 'object' member
   of the struct returned by GEDCOM_XREF_PTR (see documentation).

 - Other interface changes in the callbacks:
    - parsed tag value (integer) is passed next to the string value
    - the start record callbacks now also contain a Gedcom_val (the NOTE can
      have a value)

 - Further, various bugfixes have been made.

release 0.12 (31 December 2001):

 - The calling of callbacks is now completed.

 - Some initial documentation is available.

 - The parsed value that is returned in callbacks can now be:
     - a null value
     - a string
     - a date (struct date_value)
   See the documentation for more info.  Parsing and checking of cross-
   references will be added next.

release 0.11 (15 December 2001):

 - Initial release from Sourceforge.net (developers only !)
