 Compatibility Notes

-- [Reject unsupported naked functions][93153]
+- [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].
