It was tested and we knew that microtype will errors. But the
previous luaotfload version contained a severe bug (letterspacing
was completly broken) and we didn't want to leave this in the frozen

While the microtype error is a nuisance, the work-around is at least
easy: load luatexbase.

I wrote the author, but didn't get an answer yet.

Well if you want to do an emergency update, I would suggest to
comment this line in microtype.lua:

    microtype.warning("overwriting function `keepligature'")

should get:

    -- microtype.warning("overwriting function `keepligature'")
