This email is a "heads up" that Fedora Rawhide will soon have KiCad version 7.0.0-rc2.
Designs created with KiCad 6 and earlier are readable / editable by KiCad 7.
However, once a design is saved with KiCad 7, it will no longer be readable by KiCad 6 or earlier.
By policy, numbered Fedora releases (F36, F37, etc) will not be auto-upgraded to KiCad 7, but builds will be available on Copr for those Fedora users who want to move forward.
