Publish 2.0.

[jdm]

Any new version that includes e30e91e has to be a major version bump. While on one hand it would be nice to batch a bunch of breaking changes together, that would require a maintainer that is paying attention to this crate and has hopes and dreams for it, and that is not a good description of bincode's current maintainers :)

You should not do 2.0 for that change.

• The way to make that change backward compatibly is to deprecate SerializerAcceptor keeping the old signature and make a new trait with a different name with the new signature and a blanket impl for T: SerializerAcceptor.

• But SerializerAcceptor is not a public API anyway so you can just change it.
