Version 1.62.1 (2022-07-19)
==========================

Rust 1.62.1 addresses a few recent regressions in the compiler and standard
library, and also mitigates a CPU vulnerability on Intel SGX.

* [The compiler fixed unsound function coercions involving `impl
  Trait` return types.][98608]
* [The compiler fixed an incremental compilation bug with `async
  fn` lifetimes.][98890]
* [Windows added a fallback for overlapped I/O in synchronous reads
  and writes.][98950]
* [The `x86_64-fortanix-unknown-sgx` target added a mitigation for the
  MMIO stale data vulnerability][98126], advisory [INTEL-SA-00615].
