Do you mean to say that in the dev version of emacs, now up/down arrow
key moves the cursor by a screen line instead of moving by EOL char?

Hurray! One critical emacs modernization down, few more to go!

-----------------

as answer to your question, moving by screen line is more natural, and
is the behavior by all modern software. I don't know if this is how
emacs developers felt when the change is made, but probably similar.

the moving by screen line is a frequently requested feature, poping up
every couple of months in gnu.emacs.help or comp.emacs.

------------------

btw, what's the behavior of kill-line? Does it do screen line or EOL
line?

Yes.

The documentation of `next-line' function now says:

    If the variable `line-move-visual' is non-nil, this command moves
    by display lines.  Otherwise, it moves by buffer lines, without
    taking variable-width characters or continued lines into account.

It kills ``buffer lines''.  To kill a single display line one can move
the point to the start of that line with the arrows, select the display
line with `S-<down>' or `C-SPC S-C-n' and kill the display line with
`C-w' as usual.

It kills till EOL.

To make kill-line kill till the end of the screen line, you have to
enable visual-line-mode, which indeed changes line-wrapping, too.  (It
does wrapping only on word boundaries and not inside words.)

Hi there,

It looks the change that C-n and C-p now move by screen lines are pretty
big. Any idea why this has been set as default? What's the user case for
this?

Thank you so much.

Best,
