Version 1.55.0 (2021-09-09)
============================
Language
--------
- [You can now write open "from" range patterns (`X..`), which will start at `X` and
will end at the maximum value of the integer.][83918]
- [You can now explicitly import the prelude of different editions
through `std::prelude` (e.g. `use std::prelude::rust_2021::*;`).][86294]
Compiler
--------
- [Added tier 3\* support for `powerpc64le-unknown-freebsd`.][83572]
\* Refer to Rust's [platform support page][platform-support-doc] for more
information on Rust's tiered platform support.
Libraries
---------
- [Updated std's float parsing to use the Eisel-Lemire algorithm.][86761]
These improvements should in general provide faster string parsing of floats,
no longer reject certain valid floating point values, and reduce
the produced code size for non-stripped artifacts.
- [`string::Drain` now implements `AsRef<str>` and `AsRef<[u8]>`.][86858]
Stabilised APIs
---------------
- [`Bound::cloned`]
- [`Drain::as_str`]
- [`IntoInnerError::into_error`]
- [`IntoInnerError::into_parts`]
- [`MaybeUninit::assume_init_mut`]
- [`MaybeUninit::assume_init_ref`]
- [`MaybeUninit::write`]
- [`array::map`]
- [`ops::ControlFlow`]
- [`x86::_bittest`]
- [`x86::_bittestandcomplement`]
- [`x86::_bittestandreset`]
- [`x86::_bittestandset`]
- [`x86_64::_bittest64`]
- [`x86_64::_bittestandcomplement64`]
- [`x86_64::_bittestandreset64`]
- [`x86_64::_bittestandset64`]
The following previously stable functions are now `const`.
- [`str::from_utf8_unchecked`]
Cargo
-----
- [Cargo will now deduplicate compiler diagnostics to the terminal when invoking
rustc in parallel such as when using `cargo test`.][cargo/9675]
- [The package definition in `cargo metadata` now includes the `"default_run"`
field from the manifest.][cargo/9550]
- [Added `cargo d` as an alias for `cargo doc`.][cargo/9680]
- [Added `{lib}` as formatting option for `cargo tree` to print the `"lib_name"`
of packages.][cargo/9663]
Rustdoc
-------
- [Added "Go to item on exact match" search option.][85876]
- [The "Implementors" section on traits no longer shows redundant
method definitions.][85970]
- [Trait implementations are toggled open by default.][86260] This should make the
implementations more searchable by tools like `CTRL+F` in your browser.
- [Intra-doc links should now correctly resolve associated items (e.g. methods)
through type aliases.][86334]
- [Traits which are marked with `#[doc(hidden)]` will no longer appear in the
"Trait Implementations" section.][86513]
Compatibility Notes
-------------------
- [std functions that return an `io::Error` will no longer use the
`ErrorKind::Other` variant.][85746] This is to better reflect that these
kinds of errors could be categorised [into newer more specific `ErrorKind`
variants][79965], and that they do not represent a user error.
- [Using environment variable names with `process::Command` on Windows now
behaves as expected.][85270] Previously using envionment variables with
`Command` would cause them to be ASCII-uppercased.
- [Rustdoc will now warn on using rustdoc lints that aren't prefixed
with `rustdoc::`][86849]
