According to git bisect, the culprit is rev 3854:

    * insertion of discretionaries following explicit hyphen characters
    now happens in hnj_hyphenation(), not earlier
    * the main control loop has been simplified accordingly
    * hyphenation exceptions are now case sensitive
    * it is now possible to add extra hyphenation points to a compound word
    containing explict hyphens via a hyphenation exception
