That's good to know. Is there a difference in functionality, or is it just
a rename and will the old name be deprecated?

That's a good tip, something new I learned.

I'm trying to have snippets with similar options in the same section, so I
can declare some common options only once at the top of the section. That
does make the lines a bit shorter.

e.g.

* server-side things
  :PROPERTIES:
  :dir: /ssh:....:...
  :results: scalar
  :END:

  #+BEGIN_SRC shell :var foo=bar
   qux
  #+END_SRC


One thing that I miss though is using relative locations, especially in
combination with tramp, e.g. if I have

  :PROPERTIES:
  :dir: /ssh:root at server1:/var/web
  :results: scalar
  :END:


Then I'd like to say, now on that server do sudo

  #+BEGIN_SRC shell :dir /sudo:www-data at server1:

But instead I need to repeat the whole thing (which makes sense, I guess
the most specific `:dir` takes preference)

  #+BEGIN_SRC shell :dir /ssh:root at server1|sudo:www-data at server1:


This would be even more useful with tangle

* test
:PROPERTIES:
:dir: /ssh:root at lambdaisland.com:/root
:END:

#+BEGIN_SRC shell :tangle ./foo-bar-test
foo-bar-test
#+END_SRC


But unfortunately that just creates a local file.
