mlpd file format has changed?

mlpd File will be created when selecting SaveAs command from File menu.
But this file's format has changed from Xamarin Profiler 0.33.
When I use Xamarin Profiler 0.32, I can read this file with HeapShot.Reader libraryhttps://github.com/mono/heap-shot/. But since 0.33 I can't.
So I continued to use 0.32, but after installing Cycle8 , Xamarin Profiler 0.32 doesn't work properly.

I want know how mlpd file format has changed and the existence of library to read new mlpd file.

If there is, I wanna modify my script which I created before to investige memory leak.
Xamrin Profiler is getting better, but it's still slow and lack of some feature like comparing allocation or deallocation of objects between snapshots.
