The schedule is the following: we are compatible with previous major version. The interface had changed in early 10.0-CURRENT, and during the entire 10.0-CURRENT life it has supported the new and the old interface and this went into stable/10. When doing the change, I have pronounced this deprecation schedule. If anyone upgrades to next major: 9.x -> 10.x, or 10.x -> 11.x, including package sets, then everything will be working for him. -- Totus tuus, Glebius.
