Version 4.0.0 (NOT RELEASED YET):
---------------------------------
* REUSE compliant licensing
* Requires MSVC 2013 or higher (when building on Windows with MSVC)
* Requires CMake v3.20.0 or higher
* Brand new icalvcard library that follows the libical API.
* The icalvcal library is deprecated and will be removed sometime in the 4.x series.
Please port your icalvcal code to use icalvcard instead.
* For the C++ bindings, requires a C++11 compliant compiler
* The old src/python code is removed in favor of the glib-introspection generated
Python bindings. Requires building with -DGOBJECT_INTROSPECTION=True
* New CMake option "LIBICAL_ENABLE_64BIT_ICALTIME_T" to use 64-bit time_t implementations
on 32-bit systems (where available and supported. Windows-only so far)
* libical-glib requires glib 2.38 or higher
* libical-glib requires a C11 compliant compiler
* draft-ietf-calext-eventpub-extensions-19 (RFC 9073) support added
* draft-ietf-calext-valarm-extensions-07 (RFC 9074) support added
* libical-glib API is considered stable; no longer need to define LIBICAL_GLIB_UNSTABLE_API=1
before including <libical-glib/libical-glib.h>
* icalrecurrencetype now handled by reference rather than by value throughout the library.
* icalrecur_iterator_new() now keeps a reference to the passed rule, so that mustn't be modified as long as the iterator is in use.
* icalrecurrencetype.by_xxx static arrays replaced by dynamically allocated ones.
* GLib/Python bindings: `i_cal_recurrence_*_by_xxx*` methods have been replaced by more generic versions that take the 'by' type (day, month, ...) as a parameter.
* Allow previous recurrence iteration
* Improved performance of recurrence iterators
* GEO property has arbitrary precision (values are internally stored as strings, not doubles)
* Signatures for some functions changed to use 'bool' rather than 'int' types
* All ical*_new_clone() functions have been deprecated in favour of ical*_clone()
* Added support for Event Publishing (RFC 9073) and VALARM (RFC 9074) Extensions
* icaltzutil_get_zone_directory() can use the TZDIR environment to find system zoneinfo
* icalparser_ctrl setting defines how to handle invalid CONTROL characters during parsing
