Dota 2 Demo File Format

[himynameis]

Hi I'm trying to port demoinfo2 to linux and osx. After minor tweaking I have working executable, but when I try to parse demo file it complains "CDemoFile::Open: demofilestamp doesn't match."

And indeed demo files I'm try to parse have different PROTODEMO_HEADER_ID, "PBDEMS2" not "PBDEMS" that original demoinfo2 expects(defined in demofile.h).

I guess this has something to do with dota 2 migrating to source 2 engine? If that's the case where can I get the updated protobuf files to parse demo files from dota 2 reborn clients?

I found several repositories in GitHub but would like to know if there is any "official" version of protobuf files 3rd party developers can use.

Thanks
