I had hoped it might have been released before Javapolis, but time pressures came into play (no pun intended!) Anyway, Joda-Time 1.2, the replacement for JDK Date and Calendar, is now released!
This release fixes a few bugs and upgrades to the latest time zone information. It also includes two new calendar systems, Ethiopic and Islamic. I am still looking to expand the range of calendar systems though, there are numerous ones still to add.
Also added were convenience methods on properties to create an interval for a whole month/week etc (toInterval), and to set a date to the last day in a month (withMaximumValue).
The feedback from Joshua Bloch and the rest of the audience at Javapolis was useful, and I expect to enhance and clarify the API over the coming year.
Full details can be found on the website. As always, feedback welcome!
