Maybe I'm missing something, but isn't this irrelevant to the release given that drain_filter/exclude_if/... is unstable?

Seems plausible. Feel free to file a PR against the master branch adjusting these release notes to reflect that.

<a id="1.72.0-Stabilized-APIs"></a>

Stabilized APIs
---------------

- [`impl<T: Send> Sync for mpsc::Sender<T>`](https://doc.rust-lang.org/nightly/std/sync/mpsc/struct.Sender.html#impl-Sync-for-Sender%3CT%3E)
- [`impl TryFrom<&OsStr> for &str`](https://doc.rust-lang.org/nightly/std/primitive.str.html#impl-TryFrom%3C%26'a+OsStr%3E-for-%26'a+str)
- [`String::leak`](https://doc.rust-lang.org/nightly/alloc/string/struct.String.html#method.leak)

These APIs are now stable in const contexts:

- [`CStr::from_bytes_with_nul`](https://doc.rust-lang.org/nightly/std/ffi/struct.CStr.html#method.from_bytes_with_nul)
- [`CStr::to_bytes`](https://doc.rust-lang.org/nightly/std/ffi/struct.CStr.html#method.from_bytes_with_nul)
- [`CStr::to_bytes_with_nul`](https://doc.rust-lang.org/nightly/std/ffi/struct.CStr.html#method.from_bytes_with_nul)
- [`CStr::to_str`](https://doc.rust-lang.org/nightly/std/ffi/struct.CStr.html#method.from_bytes_with_nul)

<a id="1.72.0-Cargo"></a>

Cargo
-----

- Enable `-Zdoctest-in-workspace` by default. When running each documentation
test, the working directory is set to the root directory of the package the
test belongs to.
[docs](https://doc.rust-lang.org/nightly/cargo/commands/cargo-test.html#working-directory-of-tests)
[#12221](https://github.com/rust-lang/cargo/pull/12221)
[#12288](https://github.com/rust-lang/cargo/pull/12288)
- Add support of the "default" keyword to reset previously set `build.jobs`
parallelism back to the default.
[#12222](https://github.com/rust-lang/cargo/pull/12222)

<a id="1.72.0-Compatibility-Notes"></a>

Compatibility Notes
-------------------

- [Alter `Display` for `Ipv6Addr` for IPv4-compatible addresses](https://github.com/rust-lang/rust/pull/112606/)
- Cargo changed feature name validation check to a hard error. The warning was
added in Rust 1.49. These extended characters aren't allowed on crates.io, so
this should only impact users of other registries, or people who don't publish
to a registry.
