Why are columns equal height in Bootstrap 4 and not in Bootstrap 3?

Consider these basic and identical Bootstrap 3 and Bootstrap 4 samples. When inside the same row, in Bootstrap 3 divA seems to take as much vertical space as needed based on its own contents, whereas in Bootstrap 4 divA spans vertically as tall as divB is depending on its content.

Is there a way in Bootstrap 3 to make divA act like in v4+? How can you make two divs inside the same row have the same (not fixed) height?

I've read about the breakpoint changes in Bootstrap 4+ but I can't find any info on why these work differently.

Am I missing something?

#divA {
  background-color: red;
  border: 1px solid black;
}

#divB {
  border: 1px solid black;
}

Just use flex.

.d-flex {
  display: flex;
}
.a {
  background: red;
  width: 30%;
}
<div class="d-flex">
  <div class="a">A</div>
  <div class="b">
    Lorem ipsum dolor sit amet consectetur adipisicing elit. Nulla soluta corporis, repellat architecto error voluptatibus neque vitae tempora laudantium saepe nostrum sint ipsam dignissimos recusandae magnam illo eveniet veritatis! Unde.
  </div>
</div>
