This release is largely about stabilization. We’ve fixed some bugs, stabilized our API, and improved support for JRuby and Ruby 1.9. There are several deprecations (especially around asynchronous ‘waits’ blocks and some matchers) to go along with the fixes and features. See the release notes for full details.
Our upcoming priorities include improving the documentation, properly supporting Rails 3 and RSpec 2 and a number of other environments, and looking at all of your pull requests and issue reports. Jasmine’s backlog lives in Pivotal Tracker.
Big thanks to the Jasmine community for the pull requests; the majority of changes between 0.11.1 and 1.0 are based on user-submitted patches.
