Libraries --------- - Windows: Use a pipe relay for chaining pipes - Replace Linux Mutex and Condvar with futex based ones. - Replace RwLock by a futex based one on Linux - std: directly use pthread in UNIX parker implementation Stabilized APIs --------------- - `bool::then_some` - `f32::total_cmp` - `f64::total_cmp` - `Stdin::lines` - `windows::CommandExt::raw_arg` - `impl<T: Default> Default for AssertUnwindSafe<T>` - `From<Rc<str>> for Rc<[u8]>` rc-u8-from-str - `From<Arc<str>> for Arc<[u8]>` arc-u8-from-str - `FusedIterator for EncodeWide` - RDM intrinsics on aarch64 stdarch/1285 Clippy ------ - Create clippy lint against unexpectedly late drop for temporaries in match scrutinee expressions Cargo ----- - Added the `cargo add` command for adding dependencies to `Cargo.toml` from the command-line. [docs](https://doc.rust-lang.org/nightly/cargo/commands/cargo-add.html) - Package ID specs now support `name@version` syntax in addition to the previous `name:version` to align with the behavior in `cargo add` and other tools. `cargo install` and `cargo yank` also now support this syntax so the version does not need to passed as a separate flag. - The `git` and `registry` directories in Cargo's home directory (usually `~/.cargo`) are now marked as cache directories so that they are not included in backups or content indexing (on Windows). - Added automatic `@` argfile support, which will use "response files" if the command-line to `rustc` exceeds the operating system's limit. Compatibility Notes ------------------- - `cargo test` now passes `--target` to `rustdoc` if the specified target is the same as the host target. - rustdoc: doctests are now run on unexported `macro_rules!` macros, matching other private items - rustdoc: Remove .woff font files - Enforce Copy bounds for repeat elements while considering lifetimes - Windows: Fix potentinal unsoundness by aborting if `File` reads or writes cannot complete synchronously. </description> </patchinfo>
