+- [Make `Instant::{duration_since, elapsed, sub}` saturating][89926]
+- [Remove non-monotonic clocks workarounds in `Instant::now`][89926]
+- [Make `BuildHasherDefault`, `iter::Empty` and `future::Pending` covariant][92630]

Compatibility Notes
-------------------
- [Remove compiler-rt linking hack on Android][83822]
+- [Mitigations for platforms with non-monotonic clocks have been removed from
+ `Instant::now`][89926]. On platforms that don't provide monotonic clocks, an
+ instant is not guaranteed to be greater than an earlier instant anymore.
+- [`Instant::{duration_since, elapsed, sub}` do not panic anymore on underflow,
+ saturating to `0` instead][89926]. In the real world the panic happened mostly
+ on platforms with buggy monotonic clock implementations rather than catching
+ programming errors like reversing the start and end times. Such programming
+ errors will now results in `0` rather than a panic.
- In a future release we're planning to increase the baseline requirements for
the Linux kernel to version 3.2, and for glibc to version 2.17. We'd love
your feedback in [PR #95026][95026].
