there you are! response.json now sets content-type = application/json as it's supposed to be (if no specific content-type header is specified) Previous versions relied on the user setting the right content-type, but we noticed that nobody was properly setting it.
<tl;dr> web2py fixed a "behavioural bug", setting the proper content-type, and your view worked around a "behavioural bug" (you didn't set the content-type) that wasn't supposed to be there in the first place. Strip $.parseJSON: it's useless now because response.json doesn't return a string that can be parsed as a json object, but the json object itself.
