+Version 0.24, XX Xxx 2002 ( cvs tag libical-0-24 )
+--------------------------------------------------
+
+**** Incompatibilities with previous version ****
+
+CSTP client/server code has been removed from libicalss.
+Future versions will eventually contain a full CAP 6.0
+client/server implementation.
+
+icalproperty_get_name() is deprecated and will change
+in a future release. Use icalproperty_get_icalproperty_name()
+instead.
+
+icalcomponent_get_span() is deprecated in this release
+because it does not handle recurring events. See
+icalcomponent_foreach_recurrence() for an alternate
+interface.
+
+The icalproperty_remove_parameter() call is deprecated
+because it improperly deals with extended parameters.
+See icalproperty_remove_parameter_by_kind() for a
+compatible call.
+
+Code that deals with the TRANSPARENT property now
+uses enumeration values to get/set values instead of
+strings.
+
+The code for dealing with icalsets was overhauled. You
+will want to use the common icalset_* routines
+directly instead of calling into the icalfileset_* or
+icaldirset_* routines.
+
+A number of routines now expect to be called with
+const arguments. A number of routines now
+return pointers to const data.
+
+
+**** New Features ****
+
+Major cleanup of the time-handling routines. New API is
+available that deals with timezones much more cleanly.
+
+The regression routines in src/test are much cleaner.
+Test runs summarize which tests fail and do not
+immediately abort() like the old set of tests. A
+number of old, commented tests were resurrected.
+
+C++ Interface: New libraries libical_cxx.la and libicalss_cxx.la
+are build when you configure with the --enable-cxx option.
+
+Java Interface: A JNI interface to libical is build when
+you configure with the --enable-java option.
+
+Most of libical is now reentrant and thread safe. The Lex/Yacc
+query parser is pre-built with flex 2.5.8 and bison 1.34. To
+rebuild these files you will need to specify the --with-devel
+option. The --enable-reentrant option also adds the -D_REENTRANT
+flag for systems that require it. The build system attempts to
+add the pthread libraries to support a thread safe memory allocator
+and thread-safe error handling.
+
+A new storage mechanism for Berkeley DB 4.0 was contributed
+by Critical Path. Specify the --with-bdb4 and --with-bdb4-dir
+options to enable.
+
+Embedded code comments are slowly being migrated to be
+doxygen compliant. See http://www.doxygen.org/ for
+more on this wonderful tool.
+
+The code should now compile with non-gcc compilers. Certain
+parts of the autogenerated code were causing problems. The
+code base has also been ported to the windows Visual C
+environment.
+
+
+Version 0.23, 26 Mar 01 ( cvs tag libical-0-23 )
+------------------------------------------------
+
+**** Incompatibilities with previous versions ****
+
+icalparameter_new_rsvp
+icalparameter_get_rsvp
+icalparameter_set_rsvp
+
+ These routines now take and return ICAL_RSVP_TRUE and
+ ICAL_RSVP_FALSE instead of 0 and 1
+
+icalenum_*_to_*
+
+ These routines have been moved to icalproperty, icalparameter
+ or icalvalue
+
+
+
+Python interface: An alpha level python interface is available in
+src/python.
+
+Perl interface: A pre-alpha level interface is available in
+src/Net-ICal-Libical
+
+Code Autogeneration: Converted all of the important files in
+design-data/ to .csv files and improved the code that is generated
+from them. Now all of the enumerations for property, parameters and
+values are generated from thes files, as are the string
+representations for the enumerations. You can add a new property or
+parameter to the system simply by adding a line to the appropriate
+file in design-data/
+
+Recurrences: Improved the recurrence code by fixing bugs in MONTHLY
+recurrences and completely re-implementing expand_year_days() for
+YEARLY recurrences. Hubert V's aided in testing.
+
+Build system: JP Rosevear made several improvements to the build
+system. Now checking out the code from cvs should give to a complete
+but minimal distribution, without any of the autognerated files.
+
+Interface changes: Nearly all of the icalenum routines for converting
+between strings and enumerations have been moved out of icalenum into
+icalproperty, icalparameter and icalvalue. This means that their names
+have changed, although #defines have been added to icalenum.h to map
+back to the old names.
+
+Added src/libical/icllangbind.c that has some functions to make it
+easier to bind libical to other languages.
+
+
+Version 0.22, 15 Jan 01 ( cvs tag libical-0-22)
+----------------------------------------------
+
+Many improvements to the time routines in icaltime.c. I think that
+they actually make sense now. Note that there is an interface change
+with icaltime_from_timet() -- I removed the is_utc parameter, since
+all timet values are in UTC. Use icaltime_from_int() if you really
+want the old interface
+
+Major improvements to icalfileset. icalfileset_select now works and so
+does file locking.
+
+Minor revision to the documentation, but it does include a new section
+on file storage ( icalfileset ) and time ( icaltime.c)
+
+Lots of bug fixes and small patches.
+
+I improved the regression test in src/test/regression.c. It now have
+command line switches to select specific tests ( undocumentated, of
+course ) and more of the tests include asserts, so you can just run it
+without looking at the output. If the test runs without crashing, it
+is mostly OK.
+
+
+
+Version 0.21, 20 Nov 00 ( cvs tag libical-0-21)
+----------------------------------------------
+
+ * icalmessage.c Many routines to create new ical messages.
+
+ * icalspanlist.c Code to generate a list of the busy time f the
+ VEVENTS in a set. Also includes routiens to generate free and busy
+ lists from the spanlist, and to find the next free time after a
+ given time.
+
+ * icalvalue.c The STATUS property now has its own value type,
+ STATUS, which holds the enumeration icalproperty_status.
+
+ * icalrestriction.c Added more restrictions. Now handles mutual
+ and exclusive consitions, and checks for the reight values in
+ STATUS properties
+
+ * icaltypes.c Added routine to create durationtype from string:
+ icaldurationtype_from_string
+
+
+ * icalcomponet.c Add sever get/set convienience routines to access
+ and manipulate common component propoerties from the component
+ interface. This eliminates the need to create a lot of temporary
+ variables if you just want to change the start time of and event.
+
+
+ * icalcomponent.c Added new routines to icalcomponent:
+ _get_span -- returns the start and end times of the event in UTC
+ _get_first_real_component -- return ref to VTODO, VEVENT or VJOURNAL
+
+ * icalspanlist.c Added new class, icalspanlist, that generates a
+ list of alternating busy and free times from an icalset. The class
+ includes routines to gnerate rfc2445 busy and free lists, and to
+ get the next avaliable busy or free time after a given time.
+
+
+Version 0.20D 3 Nov 00
+-----------------------
+
+Many miscelaneous tweaks to the build system
+
+More work to icalclassify.
+
+Aded routines to icaltime.c to convert to and from specific timezones
+in Olsen format ("America/Los_Angeles")
+
+
+Version 0.20 7 Sept 00 (cvs tag libical-0-20 )
+----------------------------------------------
+
+Addedd icalclassify() which looks at a message and determine how to
+process it.
+
+Misc bug fixes and tweaks.
+
+Version 0.19 6 August 00 (cvs tag libical-0-19)
+-----------------------------------------------
+
+Created a MIME parser in icalmime.c. This will take any complex MIME
+encapsulated message and return an icalcomponent with the same
+structure. Each MIME part is represented by a component of type
+X-LIC-MIMEPART.
+
+Added MIME partsing to stow.c
+
+Added external iterators to icalcomponent. See test_iterators() in
+test/regression.c
+
+Refactored icalcluster and icalstore into icalset, icalfileset and
+icaldirset, which have a pseudo inheritance relationship between them.
+
+Fixed more memory leaks.
+
+Version 0.18a 10 June 00 ( cvs tag libical-0-18a )
+-----------------------------------------------
+
+Did the final tweaks to stow.c, a program to recieve and store iMIP
+messages.
+
+
+Version 0.18 10 June 00 ( cvs tag libical-0-18 )
+-----------------------------------------------
+
+Added libicalvcal, which includes the Versit code for parsing vCal
+files and a routine (icalvcal_convert() ) that converts a vCal object
+to an iCal object. The test program is src/test/testvcal.
+
+Added marginally functional recurrence code. The curent code does not
+handle all of the examples in rfc2445 ( which are extracted in
+test-data/recur.txt ) but it can do all of the obvious cases. See the
+test program in src/test/recur.c for an example. In particular, the
+code cannot handle the integer values in BYDAY, nor negative integers
+in BYMONTH or BYMONTHDAY. It also cannot handle BYSETPOS.
+
+Moved some code to the examples directory and improved the comments.
+
+Did a little more work on the documentation in the doc directory. The
+documentation is in LyX source, but there is a text version in
+UsingLibical.txt
+
+
+Version 0.17 15 May 00 (cvs tag libical-0-17 )
+---------------------------------------------
+
+Fixed two bugs that added extraneous '/' to test values
+
+Fixed type in internal string for the COUNTER method
+
+Eliminated a memory leak in icalparser.c
+
+
+Version 0.16a 29 April 00
+----------------------------------------------
+
+Fixed bug in icalvalue_new_from_string that caused METHOD value to
+choke on non standard input.
+
+Fixed a memory leak in icalparser_add_line -- failed to free 'line'
+
+
+Version 0.16 5 April 00 ( cvs tag libical-0-16)
+----------------------------------------------
+
+Now using automake.
+
+Substantial changes to the parser. New interfaces let you parser
+multiple components from a single stream by feading the parser object
+one line at a time.
+
+Added a STRING value type. this type is like TEXT, but does not
+backslash magic characters. It is used in PRODID and REQUEST-STATUS,
+where the '/' and ';' are literal.
+
+Added several convience functions for REQUEST-STATUS to icalenums.c
+
+Addedd a routine to icalcomponent to convert X-LIC errors to
+REQUEST-STATUS return values.
+
+Version 0.15a 5 Mar 00 (cvs tag libical-0-15a)
+---------------------
+
+Experimented with CVS
+
+Fixed icalvalue_set_text to convert escaped characters into the proper
+values.
+
+Other minor code tweaks.
+
+
+Version 0.15 7 Feb 00
+---------------------
+
+Split the storage classess ( icalstore, icalcluster, icalcalendar )
+into a seperate library, libicalss
+
+Implemented restriction checking in file icalrestrictions.c. The
+checking is not complete, but can handle the bulk of the restrictions
+described in RFC 2446.
+
+Created a new value type, METHOD. Changed METHOD property to use the
+new value. The METHOD value uses an enumeration.
+
+
+Version 0.14b
+-------------
+
+Implemented parsing of RECUR values, although it does not handle BYDAY
+specs with numbers.
+
+Fixed error in icalparser_next_line that mangled lines longer than the
+temp buffer (1024 chars.) The temp buffer is now 80 chars, and it can
+handle (apparently) arbitrary length lines
+
+Fixed severe brokenness in a value, but I forgot which one.
+
+Cleaned cruft out of the distribution, so the tarfile is smaller.
+
+
+Version 0.14a 14 Jan 00
+-----------------------
+
+Fixed bug in ROLE parameter -- missing '-' in the text of allowed values
+
+Fixed bug in X-parameters
+
+Version 0.14 11 Jan 00
+----------------------
+
+Fixed wrong value type for TRIGGER property
+
+Added Calendar object. Calendar is an aggregate of two stores and two
+clusters, and can store all of the inforamation associated with a
+calendar.
+
+icalcomponent_add_property and icalcomponent_add_component will
+complain if you try to add a component or property that is already
+part of an other component. The *_free routines wil complain if you try
+to free a linked component or property.
+
+More improvements to error handling.
+
+Parser is much more robust.
+
+Minor memory enhancements.
+
+Regression test runs without memory leaks.
+
+Version 0.13d 21Dec99
+---------------------
+
+Seperated perl interface and library
+
+Added autoconf support
+
+Scripts that generate derived properties, values and parameters now
+change source and header files inline.
+
+Changed icalstore to cluster all components with DTSTART in a month
+into a single file. This should reduce number of file accesses by a
+factor of 60.
+
+Ran code through Purify and fixed memory leaks.
+
+
+Version 0.13 16Nov99
+---------------------
+
+Yet more bug fixes! Yeah!
+
+Added better error handling. The Parser inserts X-LIC-*ERROR
+properties to warn of parsing errors.
+
+The imip source/sink programs in /src/imip is demonstrably functional.
+
+Version 0.12b 17Oct99
+---------------------
+
+More bug fixes, particularily in parse from string routines
+
+ICal::Store is mostly functional
+
+This is version is a checkpoint, not a release.

+---------------------
+
+Expanded perl interface:
+ Added 1/2 of Store module
+ Fixed bugs
+ Implemeted get_{first,next}_property
+
+Extended C interface

+ Fixed bugs
+
+
+This is version is a checkpoint, not a release.
+
+Version 0.12 27Aug99
+--------------------
+
+Added a rudimentatry perl interface
+
+This is version is a checkpoint, not a release.
+
+
+Version 0.11 11Aug99
+--------------------
+
+Eliminated most use of flex/bison -- all parsing, except for the
+values, is done in C.
+
+Cleaned up memory leaks. Purify claims that I got them all.
+
+Moved all derived component/prop/param/value code ( in .inc / .h
+files) into main files ( icalcomponent.{c,h}, icalproperty.{c,h}, etc/
+)
+
+Implemented *_clone routines.
+
+Fixed a lot of bugs.
+
+Implemented more value types. Still unimplemeneted are BINARY and RECUR
+
+Included MacOS/Code Warior files from Graham Davison
+
+
+Version 0.10 8Jul99
+-------------------
+
+Eliminated shift/reduce and reduce/reduce conflicts in the parser.
+This version is almost feature complete -- it has the basic structure
+for all of the library's functionality, and it will only require
+implementing procedure shells and fixing bugs. I think that all of the
+hard work is done...
+
+Version 0.09a,b 3,7 Jul99
+-------------------------
+
+Various improvements to the parser, added some functionality. The parser code
+is mostly complete, and should be fully functional, except for a horde of
+bugs. Also added support for X-Properties.
+
+Version 0.09 25Jun99
+--------------------
+
+Added a parser in files src/comp/icalitip.{y,l} The lexer is mostly
+functional, but the parser is not.
