As you may have seen, Lightning 1.7 has been released. There are no major UI changes, most of the bugs fixed are us running after the changes in the core Mozilla platform (most notably removing e4x support, fixing sqlite statement wrappers) and backend fixes (cure excessive getItems requests when accessing calendars).
We have some improvements for Mac users in this release though: there is now support for some gestures in the calendar views. If you are on mac (or another machine with a touchpad that supports gestures), try the usual pinch, rotate and swipe gestures in the day, week, multiweek and month views.
Also, as mentioned in the previous blog post, I have rewritten the printing support to accommodate for the e4x backend changes. There might be some kinks, so please continue testing the print support in the release and file bugs or at least comment here as necessary. We have already noticed the “All day – All day” bug.
You can view the full list of changes here on bugzilla.
Note also that if you are using the Provider for Google Calendar, you must update it to version 0.16. If you do not get the new version via automatic updates, please download it here from addons.mozilla.org.
