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 

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
