Along the same line, I read at [1]

Because it has been such a long time, and because some of the changes
potentially break existing Autoconf scripts, we are conducting a
public beta test before the final release of version 2.70. Please
test this beta with your autoconf scripts, and report any problems you
find to the Savannah bug tracker:

Maybe we should do some pro-active testing, rather than just waiting for
2.70 to get dropped on us? God knows how long it will be until 2.71.
