# Changelog ## [0.2.189](https://github.com/rust-lang/libc/compare/0.2.188...0.2.189) - 2026-07-21 ### Added - Emscripten: Add `pthread_sigmask`, `sigwait`, `sigwaitinfo`, `sigtimedwait`, `faccessat`, and `pthread_kill` ([#5270](https://github.com/rust-lang/libc/pull/5270)) - Linux SPARC: Enable the `clone3` syscall ([#4980](https://github.com/rust-lang/libc/pull/4980)) - Solarish: Add `CLOCK_PROCESS_CPUTIME_ID` and `CLOCK_THREAD_CPUTIME_ID` ([#5274](https://github.com/rust-lang/libc/pull/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](https://github.com/rust-lang/libc/commit/8c6e6710458db4d6aa0766f6f84bbf13f640237e)) ### Fixed - Musl riscv32: Rename padding fields to avoid a conflict and fix the build ([2499ff0ad993](https://github.com/rust-lang/libc/commit/2499ff0ad9936a036e78a4e0991445efee383564)) - NuttX: Fix `wchar_t` definition under Arm ([#5245](https://github.com/rust-lang/libc/pull/5245)) - Windows: Add back link names for `time`-related symbols ([#5300](https://github.com/rust-lang/libc/pull/5300)) ## [0.2.188](https://github.com/rust-lang/libc/compare/0.2.187...0.2.188) - 2026-07-21 ### Changed - Restore `Send` and `Sync` for `DIR` ([35b062263401](https://github.com/rust-lang/libc/commit/35b062263401733cd89065c6a553640f2ba51ff1)) 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`. ## [0.2.187](https://github.com/rust-lang/libc/compare/0.2.186...0.2.187) - 2026-07-20 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: ```sh 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: ```sh 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. ### Support - Add support for `aarch64-unknown-linux-pauthtest` ([#5065](https://github.com/rust-lang/libc/pull/5065)) -

2026-04-01 ### MSRV This release increases the MSRV of `libc` to 1.65. With this update, you can now always use the `core::ffi::c_*` types with `libc` definitions, since `libc` has been changed to reexport from `core` rather than redefining them.

Setting the `MUSL_V1_2_3` variable also enables some newer API unrelated to `time_t`. ### Added - L4Re: Add uclibc aarch64 support ([#4479](https://github.com/rust-lang/libc/pull/4479)) - Linux, Android: Add a generic definition for `XCASE` ([#4847](https://github.com/rust-lang/libc/pull/4847)) - Linux-like: Add `NAME_MAX` ([#4888](https://github.com/rust-lang/libc/pull/4888)) - Linux: Add `AT_EXECVE_CHECK` ([#4422](https://github.com/rust-lang/libc/pull/4422)) - Linux: Add the `SUN_LEN` macro ([#4269](https://github.com/rust-lang/libc/pull/4269)) - Linux: add `getitimer` and `setitimer` ([#4890](https://github.com/rust-lang/libc/pull/4890)) - Linux: add `pthread_tryjoin_n` and `pthread_timedjoin_np` ([#4887](https://github.com/rust-lang/libc/pull/4887)) - Musl: Add unstable support for 64-bit `time_t` on 32-bit platforms ([#4463](https://github.com/rust-lang/libc/pull/4463)) - NetBSD, OpenBSD: Add interface `LINK_STATE_*` definitions from `sys/net/if.h` ([#4751](https://github.com/rust-lang/libc/pull/4751)) - QuRT: Add support for Qualcomm QuRT ([#4845](https://github.com/rust-lang/libc/pull/4845)) - Types: Add Padding::uninit() ([#4862](https://github.com/rust-lang/libc/pull/4862)) ### Fixed - Glibc: Link old version of `cf{g,s}et{i,o}speed` ([#4882](https://github.com/rust-lang/libc/pull/4882)) - L4Re: Fixes for `pthread` ([#4479](https://github.com/rust-lang/libc/pull/4479)) - L4re: Fix a wide variety of incorrect definitions ([#4479](https://github.com/rust-lang/libc/pull/4479)) - Musl: Fix the value of `CPU_SETSIZE` on musl 1.2+ ([#4865](https://github.com/rust-lang/libc/pull/4865)) - Musl: RISC-V: fix public padding fields in `stat/stat64` ([#4463](https://github.com/rust-lang/libc/pull/4463)) - Musl: s390x: Fix definition of `SIGSTKSZ`/`MINSIGSTKSZ` ([#4884](https://github.com/rust-lang/libc/pull/4884)) - NetBSD: Arm: Fix `PT_{GET,SET}FPREGS`, `_REG_TIPDR`, and `_REG_{LR,SP}` ([#4899](https://github.com/rust-lang/libc/pull/4899)) - NetBSD: Fix `if_msghdr` alignment ([#4902](https://github.com/rust-lang/libc/pull/4902)) - NetBSD: Fix `siginfo_t` layout on 32-bit platforms ([#4904](https://github.com/rust-lang/libc/pull/4904)) - NetBSD: change definition of `pthread_spin_t` to allow arch redefinition.
