Any news? PDT 3.6 has already been released.

I'm also interested. Current setup doesn't work.
Eclipse Mars.1 Release (4.5.1) + PDT Tools 3.5.0.201506101710
results in an error message, when i press the play button.
"Cannot start a new test session since an active test session allready exists. Only a single test session is allowed with MakeGood."

EDIT: Okay, works fine now with the update.zip you provided in #80 : https://github.com/piece/makegood/releases/download/v3.2.0-dev1/makegood-3.2.0-dev1-update-site.zip
Updated to PDT 3.6 and still works. Please update reference in Eclipse Marketplace, it delivers 3.1.1
