Default revision selection on install

Maybe I’m missing the obvious, but why, when I boot from the install iso, is the default selection of release to be installed:
freepbx stable 64bit v-1.810.210.57

When a newer version,
freepbx stable 64bit v-1.811.210.57

is available as a selection?

It would seem the default should be the latest stable, no?


It will grab the new version when it installs.

Or 89? It will still grab the newest version?


Wonder what the point of giving a choice of three diff versions is then. :?
