In 2.12.3 it was possible to use
#(override-auto-beam-setting '(end 1 24 2 4) 1 8)
In a code like

\version "2.12.3"

\new Staff {
        \time 2/4
        #(override-auto-beam-setting '(end 1 24 2 4) 1 8)

        a8 a a a |
        a16 a a a a a a a |
        a32 a a a
        a a a a
        a8  a16. a32 |
        a8  a16. a32
        a32 a a a
        a a a a |
}

the attached 2.12.3-png was returned.

2.17.6, trying \set beamExceptions like:

\version "2.17.6"

%#(set-global-staff-size 18)

\new Staff {
        \time 2/4
        \set beamExceptions =
           #'((end . (
                         ((1 . 8) . (2 4))
                         ((1 . 16) . (4))
                         ((1 . 32) . (4 4 4 4)))))
        a8 a a a
        |
        a16 a a a a a a a
        |
        a32 a a a
        a a a a
        a8  a16. a32
        |
        a8  a16. a32
        a32 a a a
        a a a a
        |
}

returns the output of the 2.17.6-png.

Is there no way to do with 2.17.6 what was possible with 2.12.3?

If there's none, I'll report a bug.
