Could you please release an old version that just matches the paper?

[Passerby-ET]

It seems that the OpenVDB tech and LevelSet method have been applied in the program recently. Really a good job!
Whereas, those fantastic techs have confused some freshers such as me in the Bimocq study. Regarding code management, release versions would be good checkpoints for stage work, and I believe a release version that just matches the paper(Efficient and Conservative Fluids Using Bidirectional Mapping) would help readers a lot. I do hope the access to the original codes.
So, could you please release an old version that just matches the paper?
Best wishes! And really impressive work :)
