The new version will be ready in about two or three hours, and I'm not going for any release announcement this time (except of this blog post) since the change is rather cosmetic and doesn't affect functionality. If you can live with the fact that the new version 7.0.1 you just downloaded has 1MB of unused data which wastes your precious disk space then there is no need for you to download 7.0.2 since it is the very same in all aspects as like 7.0.1 (minus the forgotten stuff).
No harm happens, the forgotten stuff has no side effects at all, it just shouldn't be there. I made some experiments with the firefox module which is inside Slax, and I forgot to delete 2MB of useless data inthere so the resulting Slax 7.0.1 is more than 1MB bigger than it should.
