cache from beta can not be read by latest tyflow

[caypiranha]

Hello Guys, 

I am having here tyCache sequence made once by the open beta. Same to an Alembicfile.
If I want to load this into the latest tyFlow version 1.xx.xx it is not recognized by the tyCache reading Object. 
Is that intentionally to cut the last bridge between the Beta and Version 1.x or am I making something wrong? 

thanks in advance!
