Apparently this difference comes from this change in font-ots.lua near line 603. If I edit the file to put back the discretionary_code argument, the output is same with new beta.
MWE (well as close to MWE I could write, requires EBGaramond unfortunately).

Objet :Changes in hyphenations with 2016-10-12 beta
Dear list,
After ugrading to latest beta (to test typesetting with it for now), I noticed
that some words that used to be hyphenated with previous versions are no longer
hyphenated in the output, especially when the word break used to happen at a
ligature (for example ‘st’ or ‘ct’).
I had a quick look to the différences in files in
tex/texmf-context/tex/context/base directory and I see some changes to font
handling.
Is this expected ? Or is there any mechanism to get the old behaviour ? I’ll
try to build a MWE to show this if that’s required.
Thanks a lot,
Best regards
Joseph Canedo
