DownThemall! 3.0b1, which is the first preview release of the upcoming Version 3.0, was just released. It is indented for users willing to cope with bleeding edge software and reporting issues back to us.
This new release is the result of a couple of years of development, and lately focus on taking advantage of recent mozilla technologies, incl. restartless add-ons, asynchronous I/O to make things snappy and better platform integration. It also brings a lot of other major and minor new and improved features and bug fixes.
Thanks for testing
Nils – on behalf of the team
