Every direct dependency moves to its current release, golang.org/x/crypto first: keyfunc ssh to serves keys through its ssh/agent package, which has had security fixes since the pinned 2025-05 version. go.mod and go.sum only; no code changed and the SSH, age and child mnemonic test vectors pass unedited, so no derived key moves.
