I suppose I should be reading the fine manual more, but I've never
figured out the difference between \oldaddlyrics and \addlyrics.  In
any case, my manual conversions use \addlyrics.

OK, in abc, I might write:

X:1
T:Row, row, row your boat
M:6/8
L:1/8
K:C
  C3  C3  | C2  D    E3  |  E2   D   E2  F  |   G6 |
w:Row row row your boat, gen- tly down the stream
   c    c   c   G    G   G  |  E    E   E  C    C   C |
w: Mer- ri- ly, Mer- ri- ly, Mer- ri- ly Mer- ri- ly,
   G2  F E2   D | C6 |]
w:Life is but a dream.

abc2ly would have formerly (1.5.71) written a score for that as:

\score{
\notes <

\addlyrics
\context Staff="default"
{
\voicedefault
}

\context Lyrics="default"
<
{ \wordsdefaultVA }
>
>
}



and now writes:

\score{
         <<

        \context Staff="default"
        {
            \voicedefault
        }

        \addlyrics {
 \wordsdefaultVA }
    >>
}


Which looks pretty similar to me.  So if something major is going to
change about how addlyrics works, someone (I'm willing to be the
someone if I'm in the loop) should make sure that abc2ly can convert
"Row, row, row your boat".  

Now the reason I'm grumpy about this, is that if we have a two verse
song:

X:1
T:Row, row, row your boat
M:6/8
L:1/8
K:C
  C3  C3  | C2  D    E3  |  E2   D   E2  F  |   G6 |
w:Row row row your boat, gen- tly down the stream
w:Bat, bat, bat your ball, fierce- ly o'er the fence,
   c    c   c   G    G   G  |  E    E   E  C    C   C |
w: Mer- ri- ly, Mer- ri- ly, Mer- ri- ly Mer- ri- ly,
   G2  F E2   D | C6 |]
w:Life is but a dream.

The old abc2ly would have said:

\score{
        \notes <<

        \addlyrics
        \context Staff="default"
        {
            \voicedefault
        }

        \context Lyrics="default"
        <<
          { \wordsdefaultVA }
          { \wordsdefaultVB }
        >>

    >>
}

And the new one says:

\score{
         <<

        \context Staff="default"
        {
            \voicedefault
        }

        \addlyrics {
 \wordsdefaultVA }
        \addlyrics {
 \wordsdefaultVB }
    >>
}

I've never seen why convert-ly wouldn't be able to write that from the
old output of abc2ly, but instead it writes:

\score{
         <<

        \oldaddlyrics
        \context Staff="default"
        {
            \voicedefault
        }

        \context Lyrics="default"
        <<
          { \wordsdefaultVA }
          { \wordsdefaultVB }
        >>

    >>
}

Which doesn't work, and leaves the second verse out.

Now I have been hand-converting my multi-verse songs by using
something like the new output of abc2ly.  I hope that's going to go on
working.  If not, abc2ly should stop using it, of course. And it would
be good if convert-ly could handle it better than it handled the
conversion between 2.x and 2.6 where it broke all multi-verse lyrics
that I know anything about.
