This was reported on the LuaLatex list yesterday, and I extended the
example to include ConTeXt compounds. From my test folder:
%% No ligatures before dashes! Reported as: “ligatures before
%% dashes not working with LuaLaTeX 1.07.0” on comp.tex.luatex,
%% 2018-10-29 by Toni Dietze. This is also a problem with ConTeXt,
%% and is a problem with compounds as well. The problem is worse
%% with 1.09.0: With 1.07.0 (6686) it fails with the bare hyphen
%% but had no problem with en-dash, em-dash, and the compounds
%% shown below. With luatex 1.09.0 (6930) it fails with bare
%% hyphen and all shown compounds except |=|.

In one 300-page book, this hits a few times (off-course,
oft-repeated,...). Not the worst problem, but clearly a regression.

i think i know what happens ... fwiw, it's not related to the engine
(nothing really changes there nor will change but 1.07 probably is
equivalent to a by now way older context version) ... it all has to do
with some heuristics wrr to discretionary interference ...

So not an regression, but an un-caught side-effect of other changes.
In any case, 1.07 will be with us for a while -- it is part of TL18, so
probably part of some distros.
