Hi Hans,

Perhaps completely benign, but a bit strange difference I’ve spotted (because I log the ligatures of the font I use). 

After upgrade to 2016.07.30 00:26 I notice that 1 entry (only one which is a bit strange, because there are other similar entries in the description table which were not changed at all) in descriptions table in ebgaramond12-regular.tma (in tex/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/fonts/otl/ directory) has changed from

  [983766]={
   ["boundingbox"]=519,
   ["index"]=2684,
   ["name"]="ij.sc",
   ["unicode"]={ 105, 106 }, 
   ["width"]=570,
  },

To (latest beta)

[983766]={
   ["boundingbox"]=519,
   ["index"]=2684,
   ["name"]="ij.sc",
   ["unicode"]=307,  -- 307 is ij ligature whose unicode = { 105, 106 }
   ["width"]=570,
  },

Is this expected at all ? 
Thanks a lot

Best regards

Joseph Canedo
