Release Notes

dtolnay/anyhow (anyhow)

v1.0.104

Compare Source

• Update syn dev-dependency to version 3

marshallpierce/rust-base64 (base64)

v0.23.0

Compare Source

• Added more consts for preconfigured configs and engines
• Make DecodeError::InvalidLastSymbol more clear by including the decoded value
• Added SIMD-accelerated engines behind the default-on simd-unsafe feature: Simd picks the best
  instruction set at runtime (AVX2 on x86_64, NEON on aarch64) and falls back to the scalar
  GeneralPurpose engine, while Avx2 and Neon target one instruction set with no runtime
  detection and work in no_std. The engines support the standard and URL-safe alphabets.
• Update MSRV to 1.71.0
• Add support for custom padding symbols

rust-lang/futures-rs (futures-util)

v0.3.33

Compare Source

• Fix ReadLine's soundness issue regarding to exception safety. (#​3020)
• Fix unsound Send impl for IterPinRef and Iter. (#​3003)
• Fix stacked borrows violation in compat01as03 implementation. (#​3012)
• Fix memory leak in FuturesUnordered::IntoIter. (#​3005)
• Add portable-atomic-alloc feature and use it in FuturesUnordered. (#​3007)
• Re-export alloc::task::Wake. (#​3010)
• Update spin to 0.12. (#​3014)

rust-lang/libc (libc)

v0.2.189

Compare Source

Added

• Emscripten: Add pthread_sigmask, sigwait, sigwaitinfo, sigtimedwait, faccessat, and pthread_kill (#​5270)
• Linux SPARC: Enable the clone3 syscall (#​4980)
• Solarish: Add CLOCK_PROCESS_CPUTIME_ID and CLOCK_THREAD_CPUTIME_ID (#​5274)

Deprecated

• Deprecate CLONE_INTO_CGROUP and CLONE_CLEAR_SIGHAND. These overflow their types and will be changed to a larger size in the future. (8c6e6710458d)

Fixed

• Musl riscv32: Rename padding fields to avoid a conflict and fix the build (2499ff0ad993)
• NuttX: Fix wchar_t definition under Arm (#​5245)
• Windows: Add back link names for time-related symbols (#​5300)

v0.2.188

Compare Source

Changed

• Restore Send and Sync for DIR (35b062263401)

These were removed in 0.2.187 because libc does not actually make Send and Sync
guarantees about DIR (or other extern types), but this caused some crates to break.
The traits are added back for now to allow time to migrate, but will be removed again
in the future; please make sure your crates are not relying on libc::DIR: Send or
libc::DIR: Sync.

v0.2.187

Compare Source

This release contains a number of improvements related to 64-bit time_t configuration.
Of note the existing RUST_LIBC_UNSTABLE_* environment variables have been replaced
with configuration options. The new way to use these is:

RUSTFLAGS='--cfg=libc_unstable_musl_v1_2_3' cargo ...
RUSTFLAGS='--cfg=libc_unstable_gnu_time_bits="64"' cargo ...

Being able to set this via RUSTFLAGS makes it easier to only apply configuration to
specific targets (and notably, not the host if build scripts are used).

There are two other notable changes:

• The 32-bit windows-gnu targets now respect libc_unstable_gnu_time_bits

• uClibc now supports a similar configuration option:

  RUSTFLAGS='--cfg=libc_unstable_uclibc_time64'

As a reminder, these options are under active development and may change in the future
(hence the "unstable" in the name). It likely that we will harmonize everything under a
single configuration option before considering them stable.
