Is this note correct and telling the whole story? I am just now noticing that nightly (i.e. ~1.87) is warning about a lint named wasm_c_abi, which presumably reflects recent PR #138601. Is what's going on that there are two ABI changes and lints which happen to share the same lint name? If so, it might be worth a sentence to clarify the situation for users who use both stable and nightly.

This note corresponds to #133951

it seems confusing that we turned a FCW Into a hard error and then added new FCWs to the same lint that was previously hard errored

@bors r+ rollup not sure waht to do about the wasm abi lint thing, but these notes have already been included in the PR to the stable branch so are effectively "merged" already. any changes would need to also be backported to the stable branch aiui |

| ------------------- | ||
| - [The `wasm_c_abi` future compatibility warning is now a hard error.](https://github.com/rust-lang/rust/pull/133951) | ||
| Users of `wasm-bindgen` should upgrade to at least version 0.2.89, otherwise compilation will fail. | ||
| - [Remove long-deprecated no-op attributes `#![no_start]` and `#![crate_id]`.](https://github.com/rust-lang/rust/pull/134300) | ||
| - [The future incompatibility lint `cenum_impl_drop_cast` has been made into a hard error.](https://github.com/rust-lang/rust/pull/135964) This means it is now an error to cast a field-less enum to an integer if the enum implements `Drop`. | ||
| - [SSE2 is now required for "i686" 32-bit x86 hard-float targets; disabling it causes a warning that will become a hard error eventually.](https://github.com/rust-lang/rust/pull/137037) | ||
| To compile for pre-SSE2 32-bit x86, use a "i586" target instead. |

A bit late now (I'm not sure I want to stop the r+), but the removal of RustcEncodable / RustcDecodable is a breaking change we should probably note as a follow-up.

I was wondering how we missed this PR (#134272), but it is there quietly in the "Libraries" section. Yes, we should add a compat note as well, and let's do that as a followup -- on master only at this point, but that will also render in GitHub releases, at least.
