There are now a couple of points left on the todo list for the next release (see http://www.lysator.liu.se/~nisse/nettle/plan.html). Basically:
* Complete the dsa reorg (I'd appreciate all comments on that).
* Make the nettle_cipher abstraction use a const context argument for encrypt and decrypt.
* Documentation updates.
This is going to be quite a large number of incompatible changes. I think it makes sense to name the new release 3.0, and announce it as a "typical" dot-zero release, which can be expected to have some serious.
To fix reported issues, we may need a 3.1 releqase reasonably soon after 3.0, and if required, 3.1 may include additional API or ABI fixes, together with new features. After 3.1, we should get back into a more normal development, and maintain backwards compatibility.
I think this will also be a good time to upgrade the license (currently LGPLv2 or later) to a dual license, LGPLv3 or later, or GPLv2 or later.
