Note that the readme is outdated. With the upcoming 0.17 release, which is in the making for almost a year already, you can link multiple versions of ring in one executable: https://github.com/briansmith/ring/issues/1268

Similarly, while the policy is still that ring only supports the newest rust compiler version, due to the fact that there has been no update for months already, you can use it with older compiler versions.

Last, the author used to yank old versions of its library, which caused tons of downstream pains (basically, if you are a library and are using ring, I recommend you have a Cargo.lock checked into git). This yanking has stopped since 3 years already, too. Don't think this was mentioned in the readme, but I feel it's an important improvements for users.

So a great deal of things has improved, although I'd say only the first bullet point is a permanent improvement, while the second two might be regressed upon. idk.
