テストの為に Vimperator2.0 のα版がリリースされた模様。
For wider testing, we're releasing an alpha of Vimperator 2.0. We're now going into a code freeze and not adding new features to the repository, only bug fixes will go in. We invite you all to test the release and use the bug tracker to inform us with the bugs you'll find, so we can fix them.
