The first alpha for our upcoming 1.1 release is now available for download. This release is intended for testers ONLY, to get some early exposure on some of the new features under development for Thunderbird 1.1. It will contain bugs! If you are an end user using Thunderbird 1.0, please stay with 1.0. Thanks!

We welcome your feedback on all of these new features. Keep in mind they are still under development and will contain bugs. This is just an early peak.

Known Issues

Since this is an alpha release, there will be many more issues and bugs than you would find in a finished release like 1.0 was or eventually, 1.1 final. Here are some of the more noticeable ones:

• In the new Options dialog, several menulist options cannot be changed including: The ability to change the addressbook we add outgoing messages to and the address book used to allow remote images.
• Windows users cannot paste images from the clipboard into the compose window like you can in 1.0. This feature will get added to 1.1 before 1.1 final.
