I think you are mixing up things and it is the 3rd number at 50 or above
that is the development code.

In this case is "almost" 2.5.4 but not quite.
We wanted to have a tag in b2_5 before commits there ceased so that we can refer
to it by a version number vs the "tip of b2_5".
It contains various fixes on top of 2.5.3, but as far as I know, it did not
undergo the actual release testing that the point release would normally undergo.

Since the b2_5 at the time was a maintenance branch, we mostly tried to place
important fixes there that should not have broken anything.
But due to lack of proper release testing this could not be guaranteed by us,
so using it is still a bit of a leap of faith, but not quite as much as say or or the like.
