Coming maintenance release?

I was reminded that it would be good with a maintenance release of lsh.
Things to do for an lsh-2.0.5:

1. Upgrade to recent autoconf and automake (to fix the distcheck
   security problem in Makefiles generated by earlier automake).

2. Backport any portability fixes from the development branch, to make
   it compile and work on current systems.

I'm also considering

3. Upgrade the license to GPLv3.

4. Delete the bundled nettle library (to avoid shipping an ancient
   version of nettle), and do any fixes needed to work with recent
   nettle.

Anything else, e.g., any debian patches that should be integrated?

Regards,
/Niels
