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

release 0.21.0 (NOT RELEASED YET):

 - New features (see documentation):
     - C object model interface:
        - functions to add and remove records
        - functions to update timestamps in records
     - programs:
        - gedcom-check (checks standards compliancy of GEDCOM files)

 - Some compatibility with PAF (Personal Ancestral File) is added (thanks
   Hans Fugal).

release 0.20.0 (30 December 2002):

 - The release numbering scheme is changed to a three-part version number.
   Patches will just update the last digit.

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

 - A lot of new features (see documentation):
     - callback interface:
        - functions to manipulate cross-references (add, delete, link and
          unlink)
        - functions to manipulate dates (strings to numbers and vice versa,
          conversion between calendars, ...)
        - 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
        - gedcom-config script for linking and compilation flags

 - The library now comes with an extra shared library (libutf8tools),
   which needs to be linked in in any programs that use the gedcom parser
   library (you can use the script 'gedcom-config' to generate link and
   include flags).  You can use utf8tools in totally unrelated programs too.

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

 - INTERFACE CHANGE: the return value of gedcom_init() has changed from
   void to int to be able to return a status.

 - 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 !)
