I've just released Cucumber 1.3.17. This releases a couple of changes to the formatters that Björn Rasmusson has been working on to allow embedding of images in JSON and HTML reports, as well as proper support for Scenario Outlines in the JSON formatter. If you're using the excellent free cucumber-reporting tools you'll appreciate this.

I'm hoping this is the last release in the 1.x line. We're closing down on the last remaining bugfixes for Cucumber 2.0, and I expect a third beta to be out very soon.
