What’s new for Windows in 0.1.125

Released Oct 28, 2026

Kyle sets itself up for each of your companies on this computer, and starts working as soon as its first run finishes.

  • The first run's last step starts Kyle right away, instead of waiting for your next sign-in.
  • A second company's first run on the same computer joins the Kyle already there: one home, set up for each company.
  • A stair on a proposal stays in the base bid unless you said, in your own words, to carry it as an alternate, and the proposal check quotes you.
  • Also in this release: everything else on main since 0.1.124.
