We released Zimbra 4.0.2 today and there were a few extras that came along for the ride. First off the Fedora Core 5 build is now GA. We also added a new developer/preview release on Ubuntu. This has been a popular hack in our forums for sometime.
Here’s a sample of some of the other changes/fixes in 4.0.2:
- perf improvements for IMAP (new MySQL indexes)
- > 2GB support in the Zimbra Outlook Connector
- i18n and some l10n for the Zimbra Outlook Connector
- disabling AS/AV causes mail deferral
- cursor fails to appear in Firefox
- mailbox quota page does not contain any entries
- several all day event and timezone bugs fixed
Keyboard shortcuts and navigation are indispensable time savers for an application’s frequent and power users. Who among us has not quickly learned the keyboard shortcuts for performing common tasks within an application that we use regularly?
Unfortunately, one of the more common complaints against web-based applications is that they are, in many instances, lacking when it comes to supporting keyboard shortcuts and navigation. Frankly, the lack of keyboard support (both shortcuts and navigation) is something that has annoyed me about the Zimbra Collaboration Suite (ZCS), and it is something that I have been wanting to add to both Kabuki (the Zimbra Ajax Toolkit) and the ZCS; however, I didn’t want to just stuff in some basic keyboard shortcuts and call it a day. Instead, I wanted to have a go at implementing the same level of keyboard support that most traditional UI toolkits and desktop applications support. This actually turned out to involve quite a bit of work - for example, since only input elements may have focus (in most browsers) we needed to simulate and track focus for toolkit components which frequently have no native input element associated with them - but at the end of the day, I think it was worth the effort.

To continue the Zimbra blog series on Ajax (recent entries include Ajax innovation is about the server, Ajax optimization techniques (presented at OSCON), OpenAjax update, and Ajax’s impact on scaling), we wanted to offer some general thoughts on securing Ajax applications gleaned, of course, from our Zimbra experience.
