The primary changes are in the build system.

It shouldn't be hard to port blocks written for 2.8.  Are you
currently building your blocks in the main tree, or outside of it, as
suggested in the "How to Write a Block" article?

  http://www.gnu.org/software/gnuradio/doc/howto-write-a-block.html

If you follow the strategy in "How to Write a Block", I think you'll
find the port straight-forward.  Most likely just some Makefile.am
hacking.
