warning: unresolved link to `SubgroupPoint::from_bytes`
##[warning]    --> jubjub/src/lib.rs:1032:27
     |
1032 |     /// other cases, use [`SubgroupPoint::from_bytes`] instead.
     |                           ^^^^^^^^^^^^^^^^^^^^^^^^^^^ unresolved link
     |
     = note: `#[warn(broken_intra_doc_links)]` on by default
     = help: to escape `[` and `]` characters, add '\' before them like `\[` or `\]`

I think that should be either [SubgroupPoint::from_bytes] or

[`SubgroupPoint::from_bytes`](SubgroupPoint::from_bytes)

[str4d]

The syntax there is correct. What's missing is an import, which I'll add shortly.

[ebfull]

There is a RELEASES.md file that I've been using to inform users of bls12_381 about the API changes. Can we update this PR with that?

[str4d]

@daira I fixed the intra-doc link in #281.

@ebfull once #281 is merged, I'll rebase this PR and then amend the bls12_381 and jubjub commits to also update their RELEASES.md files.

[str4d]

Rebased on master after merging #281. I'll edit the RELEASES.md files next.

[str4d]

Force-pushed to update the bls12_381 and jubjub release commits with release notes.

[str4d]

Aaand fixed some copy-pasta 🍝
