From the project

74HCT6526

For a stack to work properly, is mandatory that all boards share the same MAJOR.MINOR versión. Any change than renders a board incompatible with the previous releases triggers a new MINOR version. If a version only includes fixes, but does not alter the buses, it's only a new revision. There may be some cases where boards with different MAJOR.MINOR version can actually work together, but this is not something I can guarantee or predict. A deep look at the schematics to understand the differences between releases is needed to actually confirm this.
