Release Notes

Breaking Changes

If you are using scripts to manage arcK, these scripts will be broken due to change in command syntax when upgrading from 1.2.x to 1.3.x

  • Enhancement: syntax change. Commands now: make, verify and restore followed by flags, e.g. arck make -v /path/ /dest/path/ or arck restore /path/to/file.m /dest/path/ more
  • Enhancement: if you specify a file, does not tar first, encodes directly
  • Tweak: wizard mode removed
  • Enhancement: rewritten documentation
  • Built with Golang version 1.24.2
