Many thanks for your new beta, Hans.
From the previous beta with the new hyphenator, I have two issues.
With the new hyphenator, \hyphenation isn’t honored, such as in this sample:
\setuphyphenation[method=traditional]
     \hyphenation{Nietz-sche}
     \starttext
     \hsize\zeropoint
     Nietzsche
     \stoptext
Has the command been deprecated with the new hyphenator?
no, on the todo list is a variant (in fact you can add pretty complex 
patterns in different ways already)
...
The second issue is the ability to enable underscore hyphenation. Is
there any way to apply the following definition to \hyphenatedurl?
\unexpanded\def\underscorehyphenation#1%
    {\dontleavehmode
     \begingroup
     \prehyphenchar\minusone
     \localrightbox{\llap{\smash{\lower.1ex\hbox{_}}}}%
     \setbox\scratchbox\hbox{#1}%
     \prehyphenchar`-\relax
     \unhbox\scratchbox
     \endgroup}
(This is adapted from the last sample in lang-url.mkiv.)
no need to mess like that:

\startluacode

     local function addfunnyhyphen(tfmdata)
         local exheight = tfmdata.parameters.xheight
         local emwidth  = tfmdata.parameters.quad
         local width    = emwidth
         local height   = exheight / 10
         local depth    = exheight / 2
         tfmdata.characters[0xFE000]   = {
             width    = 0,
             height   = 0,
             depth    = 0,
             commands = {
                 { "right", -width },
                 { "down", depth },
                 { "rule", height, width },
             }
         }
     end

     fonts.constructors.newfeatures("otf").register {
         name        = "funnyhyphen",
         description = "funny hyphen",
         manipulators = {
             base = addfunnyhyphen,
             node = addfunnyhyphen,
         }
     }

\stopluacode

\definefontfeature[default][default][funnyhyphen=yes]

\starttext

     \prehyphenchar"FE000

     \hsize 1mm

     averylongword

\stoptext
