Each open issues has a pull request pending, in addition to a few extra pull requests. As soon as those are all merged in, I'm recommending that we tag 0.1.1 (Monday or Tuesday).
I'll share a more detailed changelog when we announce the release. Off the top of my head, the big change that 0.1.1 introduces is that it processes all the markup in one pass, whereas previously it was evaluating the preprocessor directives (ifdef, include and attribute entries) on a first pass, then going back and parsing all the other markup (see issue #143 ). This split was causing processing directives to be evaluated differently than in AsciiDoc. That's now resolved.
We've also been working on a default stylesheet for Asciidoctor. That's planned for 0.1.2, which you can track here:
