> What do people think about releasing libraries with 1.1 draft spec support?  Gregg Kellogg has done some great work adding 1.1 support to jsonld.js and pyld.  We'd like to release that code for people to use but I'm unsure on how to best do it.  Once the code is out there people will start using and depending on the features.  If changes need to be made before 1.1 is final, it would be nice to be able to change anything as needed.

We want to avoid needing tricky compatibility code for possible old draft behavior.  Is this enough of a problem to even need a solution?  "@version": "1.1-draft-1" or similar might be nice, but that doesn't have the 1.0 processor fail behavior.  "@version": [1.1, "draft-1"] could work, and arrays would even allow a string "1.1" version, but maybe that's too confusing.  Other schemes are possible too, for 1.1 processor to read other flags, etc.  Thoughts?

People have been using my Ruby JSON-LD library for a while, which has these issues released. Indeed, semantic versioning is a way to introduce a breaking change to the library, but you have a point about people creating data which relies on this.

Not sure about putting more semantics in @version. If the eventual WG decides to break compatibility with CG 1.1 issues, then they would likely need to signal this with a different version number.

In whatever state, I think the libraries need to be released, if only as a pre-release, as people do rely on features such as id maps now, and likely other features.
