Edit: 1.1b fixes an auto shutdown issue in burpsuite, I would highly recommend this release over 1.1a. The rest of the post still applies.

This is a small release but a useful one.

Release 1.1b adds the ability to parse projects for portions of siteMap and proxyHistory. For example, the following will only respond with the proxyHistory request.headers and request.body. Note, the URL is always included:

java -jar -Djava.awt.headless=true [PATH_TO burpsuite_pro.jar] --project-file=[PATH TO PROJECT FILE] \
  proxyHistory.request.headers, proxyHistory.request.body

This should result in significant speed improvements as parsing will ignore response.body which can be very large. Conversely, if you only wanted to parse the proxyHistory response body for interesting things you could do:

java -jar -Djava.awt.headless=true [PATH_TO burpsuite_pro.jar] --project-file=[PATH TO PROJECT FILE] \
  proxyHistory.response.body
