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
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.

Hi Joseph, French hyphenation is unknown to me, but I have a different approach.
MWE (well as close to MWE I could write, requires EBGaramond unfortunately).
\language[fr]
The document main language is invoked in ConTeXt with: \mainlanguage[fr]
\setupalign[hanging, lesshyphenation, hz]
I suspect that if you ask for less hyphenation, you get it. See my sample: \mainlanguage[fr] \setupalign[lesshyphenation] \starttext \hyphenatedword{T advint qu'il y eut famine au pays/ oultre la premiere famine/ qui fut au temps de Abraham. Et Izahak s'en alla vers Abimelech Roy des Philisthins en Gerar} \stoptext \hyphenatedword is your friend here. I get different results if I comment the second line (to get normal hyphenation). I wonder whether this might be causing the issue you’re experiencing. Just in case it helps, Pablo -- http://www.ousia.tk

Hi Joseph,
French hyphenation is unknown to me, but I have a different approach.
When messing with disc nodes one can argue if some of then need to become discretionary nodes or keep their other type. This change keeps it more original (of course one can argue about it) which has some consequence for the number of passes that tex makes (pass without hyphenation, pass with hyphenation, pass with hyphenation and stretch) i plan to makes things a bit more configureable in the alternative hyphenator one can also argue that the first pass can be omitted (i.e. always go for the best solution)
MWE (well as close to MWE I could write, requires EBGaramond unfortunately).

Great, thanks a lot Hans. Not a big issue (some glues are bit more stretched than before here and there, but not to the point to have underfulls), but curious to understand.
