[74784]: https://github.com/rust-lang/rust/issues/74784

Version 1.45.1 (2020-07-30)

[73078]: https://github.com/rust-lang/rust/issues/73078
[74509]: https://github.com/rust-lang/rust/pull/74509
[74457]: https://github.com/rust-lang/rust/pull/74457

Version 1.45.0 (2020-07-16)
==========================

Language
--------
- [Out of range float to int conversions using `as` has been defined as a saturating
  conversion.][71269] This was previously undefined behaviour, but you can use the
   `{f64, f32}::to_int_unchecked` methods to continue using the current behaviour, which
   may be desirable in rare performance sensitive situations.
- [`mem::Discriminant<T>` now uses `T`'s discriminant type instead of always
  using `u64`.][70705]
- [Function like procedural macros can now be used in expression, pattern, and  statement
  positions.][68717] This means you can now use a function-like procedural macro
  anywhere you can use a declarative (`macro_rules!`) macro.

Compiler
--------
- [You can now override individual target features through the `target-feature`
  flag.][72094] E.g. `-C target-feature=+avx2 -C target-feature=+fma` is now
  equivalent to `-C target-feature=+avx2,+fma`.
- [Added the `force-unwind-tables` flag.][69984] This option allows
  rustc to always generate unwind tables regardless of panic strategy.
- [Added the `embed-bitcode` flag.][71716] This codegen flag allows rustc
  to include LLVM bitcode into generated `rlib`s (this is on by default).
- [Added the `tiny` value to the `code-model` codegen flag.][72397]
- [Added tier 3 support\* for the `mipsel-sony-psp` target.][72062]
- [Added tier 3 support for the `thumbv7a-uwp-windows-msvc` target.][72133]

\* Refer to Rust's [platform support page][forge-platform-support] for more
information on Rust's tiered platform support.


Libraries
---------
- [`net::{SocketAddr, SocketAddrV4, SocketAddrV6}` now implements `PartialOrd`
  and `Ord`.][72239]
- [`proc_macro::TokenStream` now implements `Default`.][72234]
- [You can now use `char` with
  `ops::{Range, RangeFrom, RangeFull, RangeInclusive, RangeTo}` to iterate over
  a range of codepoints.][72413] E.g.
  you can now write the following;
  ```rust
  for ch in 'a'..='z' {
      print!("{}", ch);
  }
  println!();
  // Prints "abcdefghijklmnopqrstuvwxyz"
  ```
- [`OsString` now implements `FromStr`.][71662]
- [The `saturating_neg` method as been added to all signed integer primitive
  types, and the `saturating_abs` method has been added for all integer
  primitive types.][71886]
- [`Arc<T>`, `Rc<T>` now implement  `From<Cow<'_, T>>`, and `Box` now
  implements `From<Cow>` when `T` is `[T: Copy]`, `str`, `CStr`, `OsStr`,
  or `Path`.][71447]
- [`Box<[T]>` now implements `From<[T; N]>`.][71095]
- [`BitOr` and `BitOrAssign` are implemented for all `NonZero`
  integer types.][69813]
- [The `fetch_min`, and `fetch_max` methods have been added to all atomic
  integer types.][72324]
- [The `fetch_update` method has been added to all atomic integer types.][71843]

Stabilized APIs
---------------
- [`Arc::as_ptr`]
- [`BTreeMap::remove_entry`]
- [`Rc::as_ptr`]
- [`rc::Weak::as_ptr`]
- [`rc::Weak::from_raw`]
- [`rc::Weak::into_raw`]
- [`str::strip_prefix`]
- [`str::strip_suffix`]
- [`sync::Weak::as_ptr`]
- [`sync::Weak::from_raw`]
- [`sync::Weak::into_raw`]
- [`char::UNICODE_VERSION`]
- [`Span::resolved_at`]
- [`Span::located_at`]
- [`Span::mixed_site`]
- [`unix::process::CommandExt::arg0`]

Cargo
-----

Misc
----
- [Rustdoc now supports strikethrough text in Markdown.][71928] E.g.
  `~~outdated information~~` becomes "~~outdated information~~".
- [Added an emoji to Rustdoc's deprecated API message.][72014]

Compatibility Notes
-------------------
- [Trying to self initialize a static value (that is creating a value using
  itself) is unsound and now causes a compile error.][71140]
- [`{f32, f64}::powi` now returns a slightly different value on Windows.][73420]
  This is due to changes in LLVM's intrinsics which `{f32, f64}::powi` uses.
- [Rustdoc's CLI's extra error exit codes have been removed.][71900] These were
  previously undocumented and not intended for public use. Rustdoc still provides
  a non-zero exit code on errors.

Internals Only
--------------
- [Make clippy a git subtree instead of a git submodule][70655]
- [Unify the undo log of all snapshot types][69464]
