1.3 of the Calendar released!

If you wonder why it has been so long between 1.0 and 1.3 of the CalCore/CalZope/CPSSharedCalendar trio, then the answer is not only vacation, and a whole bunch of big new features, but also that every time I have been close to releasing a new version, I have first released it to some of our trusty customers for testing. And they have promptly found bugs, which I then fixed, and made a new release, and so on.

After the release of 1.0, several additional customers have installed the new calendar, and we also have people using it outside of CPS altogether. At this point I dare to say that the new calendar is both prettier, faster and more stable than the old CPSCalendar. The type of bugs that has been popping up lately are mostly translation and usability problems, where the calendar doesn't behave exactly as you would expect it to. An upgrade is warmly recommended.

The major new features in 1.3 are:

• Major speed increases for big installations.
• Event coloring according to type.
• Calendar "stacking": You can create calendars which display the events of several calendars as if they were one.
• Migration from the older CPSCalendar.
• Support for Zope 2.7 and 2.8, CMF 1.4 and 1.5, CPS 3.2 and 3.3.
• Localization of date format.

Of course, there are also many bugfixes, most having to do with translations, something that always takes a long time.

Separate releases per target

There are now several separate releases. This is mostly because the install instructions just got way to complicated, and it's also an effect of the desire to release a non-zope release of the CalCore library that does all the heavy calendar lifting, so the rest of teh Python world can use it. CalCore requires some libraries from Zope 3,  so I made a CalCore-bundle release that includes these packages, and which is easily installable into any non-zope python installation with the standard distutils.

There is also a CalZope bundle that includes all you need to install it under Zope or CMF (except for Five and Zope 3), which you need if you run Zope 2.7.

And of course, we also have the CPSSharedCalendar bundle, which includes all the products you need to install the calendar on CPS (again not including Five and Zope 3).
