Icemac.ab.calendar

==================

- Fix icons of links introduced in version 2.1 to be rendered equally on
Firefox, Safari, Internet Explorer and Chrome.

================

Features
--------

- Add links in month view to easily access the previous resp. next month.

- Rename the links to the month view and to the year view and add titles to
them.


Other changes
-------------

- Bring the test coverage to 100 % including the tests itself and the test
infrastructure but without the need to run the selenium tests to achieve
this.

- Update to changes in test infrastructure in `icemac.addressbook >= 4.0`.

================

Backward incompatible changes
-----------------------------

- Update test infrastructure to `icemac.addressbook >= 3.0`, thus update to
`py.test >= 2.8`. The fixtures which can be reused where moved to
``icemac.ab.calendar.fixtures``. ``icemac.ab.calendar.conftest`` should no
longer be used from foreign packages as this leads to problems with the new
py.test version.


Bugs
----

- The computation of Biweekly events was fixed: There are now always two weeks
between the events. Previously it could only be one if the recurrence in the
previous month was in the last week of the month.

- Fix the bug with daylight saving time adding one hour to each event during
DST for the year calendar which was already fixed for the month calendar in
version 1.8.

=================

- Adapt code so `grokcore.component >= 2.6` can be used.

- Fix sort order of events with the same datetime again. They are now
sorted by the title of the category.

- Adapt styling to `icemac.addressbook >= 2.10`.

===================

- Stabilize the sort order of events with the same datetime. They are now
sorted by category.

===================

- Fix an error in calendar display when rendering a user defined field which is
only defined on IEvent but not on IRecurringEvent.
