> Tails 4.19 will be a major release,
This situation is not so common. IIRC boyska has not faced it yet,
and other contributors might welcome a reminder, so here we go:
- until the freeze, code MRs should target the devel branch, except
  for bug fixes we would want included in a potential 4.18.1, in which
  case they should target the stable branch
- after the freeze, code MRs should target:
  - the testing branch, if they're for 4.19
  - the stable branch, for bug fixes we would want included in
    a potential 4.18.1
  - the devel branch, if they're for 4.22, our next major release
