On two development machines, I have installed Foundation 6.31 (npm/SASS).
I would really like to give 6.4-rc a spin, but I’m a bit reluctant since I have several F6.3 customer projects to work on. It seems that 6.4 changes a lot of the basics (flex, XY-grid, etc.) and I don’t want to break anything.
Is it still possible (and safe) to use/work on the older 6.x projects after installing a 6.4 foundation-cli?
Is it also possible to "foundation new" a 6.31 project?
