fyi: datasets created with version v0.14.25 are not backward compatible with v0.14.24

[erjel]

I cannot read datasets created with version 0.14.25 onward with version 0.14.24.

Error message:

I will update my environments to the newer versions now, I just want to make you aware of the breaking change.
