Thunderbird 3.0 has finally been released.
While Mozilla's browser project has undergone steady development, Thunderbird has seemed to lag behind. Once it hit the 2.0 milestone, no major revisions have come along leading some of us who use Firefox's sidekick wondering if the team had all gone out to a permanent lunch.
A few notes:
The most obvious feature addition is tabs for e-mail. This works similarly to the now standard feature in every major web browser and can be used in a number of ways. Since I have multiple e-mail accounts, I've found the most natural of these to be having each account open in its own tab. I can then go back and forth between tabs and open individual folders in that tab or open those in yet another tab if I want. I'm still playing with it to find uses, but that's where I am with it now.
Speaking of multiple accounts, this version of Thunderbird now has something called "Smart Folders." It will organize all your Inbox's across your e-mail accounts into a single Inbox for reading if you want. The folders for those accounts remain to keep everything organized the way you want, but this would allow you to read all your new mail without switching around between them. I, personally, don't think I'll use this, and the feature can be turned off.
Gmail's IMAP now works.
The search function has been greatly improved. You'll notice when you first start up the new version that Thunderbird will spend a lot of time (given my volume of e-mail and usenet archives, about 274 truckloads plus a spare trailer of time) indexing everything. After it's done, the continued indexing of new messages seems mostly invisible. I'll note also that while the indexing was taking place it didn't interfere with anything and that I could read/send/browse my mail at will, but it did put a tax on my CPU while it was working.
Font handling seems much improved in the Linux version.
Almost none of my former extensions currently work except for Engimail, which is the bridge between Thunderbird and GPG. (Interestingly, as you can see in the pic above, the names of some of these extensions that don't work do still appear in the About window and are appended to the client header still.) A few themes have been updated, but not many, and some that claim to be updated aren't. Given the interface makeover, all old themes will need substantial work to function with this version. Most of the extensions I did use aren't killers, but one, the interface between T-Bird and Gmail's calendar will be missed until it is updating, assuming it is. I say "assuming" because it has been so long between T-Bird updates, I wonder how many developers are still paying attention.
Other than that, I've not run into any problems, and this version is noticeably more responsive than its predecessor. That's all for now.
