I wondered this very same thing when I looked at the new version.  I
would assume the sources document changes, but it's rather wastefull
to send several hundred K-bytes across the net for that purpose alone.

So, I just ran diff on the file "cmds.doc" to see what commands were
added.  This was quite some time ago and I remember it not being as
easy as it sounds - that I needed to run the files through a sed
script to get them in the same format.  But hey, you are in luck, I
saved the output for posterity (and the fact that it took me several
hours to produce...)

Commands in 4.9 not in 4.14
---------------------------
entry "prefix-1" "Command"
entry "prefix-2" "Command"
entry "prefix-3" "Command"
entry "ansi-codes" "Command"

Commands new to 4.14
--------------------
entry "bind-keymap-to-key" "Command"
entry "c-argument-indentation" "Variable"
entry "dbx-format-string" "Variable"
entry "make-keymap" "Command"
entry "process-bind-keymap-to-key" "Command"
entry "process-dbx-output" "Command"
entry "read-only-mode" "Command"
entry "shift-region-left" "Command"
entry "shift-region-right" "Command"
entry "stop-process" "Command"

A few things to note:

1) Most of the new commands (relating to process control) are
unsupported under messy-dos.

2) The C-mode variables to control formatting have changed.  I don't
remember exactly how, but the function descriptions do a "reasoanble"
job of documenting the changes.  I fixed my "jove.rc" and everything
was hunky-dory

3) The shift-region-[left|right] commands are most usefull when
editing programs.

Unfortunately, it seems as if a few bugs have been introduced.  :-(

While most are quite minor (they existed in all previous versions I
have used, so I just work arround them) there is one that does annoy
me.  When running a subshell (either through shell-command or make) a
filename passed to Jove is used as the executable name.  That doesn't
sound too clear (at least to me, and I wrote it) so let me give an
example.

Assume you have a "/bin" directory in you path with at least two
executables, jove.exe and ls.exe.  From any directory, bring up jove
with the command "jove t.t" Invoke shell-command, either from a
function key if you have it bound, or from execute-named-command
(ESC x) and send the command "ls" to the shell.  Jove parses the name
of the file you put on _Jove's_ command line as the name of the file
to execute, e.g. if you were in /tmp and brought up Jove with
"jove t.t", shell-command(ed) "ls", Jove would give the error:
c:/tmp/t.t not found.

Previous versions of Jove didn't have this bug, and since I'm not
running any kind of fancy shell (csh, 4dos, etc) this is most likely a
bona-fide bug.

You can work arround the problem by bringing up Jove with no filenames
or options and then load files as you need them, but that's a pain...
However, having tried MicroEmacs, Freemacs, and ME_CD, I *still*
prefer Jove despite its bugs and peculiarities.
