What’s new:

In MacOSX, [csound~] will accept Max style paths as well as POSIX style
paths.  [dp.pathconvert] is no longer necessary.

Added “open” message that does the same thing as double-clicking on the
[csound~] external; it opens the current csd or orc/sco file(s).

Added “run” message that allows you to execute command line commands.

Help patch has been improved and expanded.
