CalDavZAP 0.12.2rc & InfCloud 0.12.2rc available at:

demos:

And the changes (the first one is VERY important and fixes lot of bugs /+ adds support for previously unsupported things/ at once):

- full RFC2445 support - RRULE processing is now performed by rrule.js (see: https://github.com/jakubroztocil/rrule); thanks to this library we now support/expand all recurrences, although the most exotic ones are "read-only" (for these you will see "Other (modification not supported)" in the interface)
- updated timezone.js to latest IANA timezone database
- other improvements and fixes

known bugs:

- incomplete translations - the "Other (modification not supported)" string needs update for all localizations (except EN, CZ, SK, HU)

Thanks for help, suggestions, bug reports, ...
