- [Rustc now correctly relates the lifetime of an existential associated
type.][71896] This fixes some edge cases where `rustc` would erroneously allow
you to pass a shorter lifetime than expected.

- [Rustc now dynamically links to `libz` (also called `zlib`) on Linux.][74420]
The library will need to be installed for `rustc` to work, even though we
expect it to be already available on most systems.
- [Tests annotated with `#[should_panic]` are broken on ARMv7 while running
under QEMU.][74820]
- [Pretty printing of some tokens in procedural macros changed.][75453] The
exact output returned by rustc's pretty printing is an unstable
implementation detail: we recommend any macro relying on it to switch to a
more robust parsing system.
