It works for me. Did you run cargo update?

[gnunicorn]

Sorry, I was trying against master || release and I missed the update of router. Examples work fine then (release still doesn't though :( )

[sunng87]

Yes, because handlebars 0.19 has a little backward incompatible change. I'm planning a few releases to cover (iron 0.3 + handlerbars 0.19) and (iron 0.4 + handlebars 0.19).

tl;dr I will release it tonight.
