Version 1.30.0 (2018-10-25)
2+
==========================
3+
4+
Language
5+
--------
6+
- [Procedural macros are now available.][52081] These kinds of macros allow for
7+
more powerful code generation, there is a [new chapter available][proc-macros]
8+
in Rust Programming Language book that goes further in depth.
9+
- [You can now use keywords as identifiers using the raw identifiers
10+
syntax (`r#`).][53236] e.g. `let r#bool = true;`
11+
- [Using anonymous parameters in traits is now deprecated with a warning and
12+
will be a hard error in the 2018 edition.][53272]
13+
- [You can now use `crate` in paths.][54404] This allows you to refer to the
14+
crate root in the path. e.g. `use crate::foo;` refers to `foo` in `src/lib.rs`.
15+
- [Using a external crate now no longer requires being prefixed with `::`.][54404]
16+
e.g. previously using a external crate in a module without a use statement
17+
required `let json = ::serde_json::from_str(foo);` can now be written
18+
as `let json = serde_json::from_str(foo);`.
19+
- [You can now apply the `#[used]` attribute to static items to prevent the
20+
compiler from optimising them away even if they appear to be unused.][51363]
21+
e.g. `#[used] static FOO: u32 = 1;`
22+
- [You can now import and reexport macros from other crates with the `use`
23+
syntax.][50911] Macros exported with `#[macro_export]` are now placed into
24+
the root module of the crate. If your macro relies on calling other local
25+
macros it is recommended to export with the
26+
`#[macro_export(local_inner_macros)]` attribute so that users won't have to
27+
import those macros.
28+
- [`mod.rs` files are now optional.][54146] Previously if you had a `foo` module
29+
with a `bar` submodule, you would have `src/foo/mod.rs` and `src/foo/bar.rs`.
30+
Now you can have `src/foo.rs` and `src/foo/bar.rs` to achieve the same effect.
31+
- [You can now catch visibility keywords (e.g. `pub`, `pub(crate)`) in macros
32+
using the `vis` specifier.][53370]
33+
- [Non-macro attributes now allow all forms of literals not just
34+
strings.][53044] e.g. Previously you would write `#[attr("true")]` you can now
35+
write `#[attr(true)]`.
36+
- [You can now specify a function to handle a panic in the Rust runtime with the
37+
`#[panic_handler]` attribute.][51366]
38+
39+
Compiler
40+
--------
41+
- [Added the `riscv32imc-unknown-none-elf` target.][53822]
42+
- [Added the `aarch64-unknown-netbsd` target][53165]
43+
44+
Libraries
45+
---------
46+
- [`ManuallyDrop` now allows the inner type to be unsized.][53033]
47+
48+
Stabilized APIs
49+
---------------
50+
- [`Ipv4Addr::BROADCAST`]
51+
- [`Ipv4Addr::LOCALHOST`]
52+
- [`Ipv4Addr::UNSPECIFIED`]
53+
- [`Ipv6Addr::LOCALHOST`]
54+
- [`Ipv6Addr::UNSPECIFIED`]
55+
- [`Iterator::find_map`]
56+
57+
The following methods are a replacement methods for `trim_left`, `trim_right`,
58+
`trim_left_matches`, and `trim_right_matches`. Which will be deprecated
59+
in 1.33.0.
60+
- [`str::trim_end_matches`]
61+
- [`str::trim_end`]
62+
- [`str::trim_start_matches`]
63+
- [`str::trim_start`]
64+
65+
Cargo
66+
----
67+
- [`cargo run` doesn't require specifying a package in workspaces.][cargo/5877]
68+
- [`cargo doc` now supports `--message-format=json`.][cargo/5878] This is
69+
equivalent to calling `rustdoc --error-format=json`.
70+
- [You can specify which edition to create a project in cargo
71+
with `cargo new --edition`.][cargo/5984] Currently only `2015` is a
72+
valid option.
73+
- [Cargo will now provide a progress bar for builds.][cargo/5995]
74+
75+
Misc
76+
----
77+
- [`rustdoc` allows you to specify what edition to treat your code as with the
78+
`--edition` option.][54057]
79+
- [`rustdoc` now has the `--color` (Specify whether to output color) and
80+
`--error-format` (Specify error format e.g. `json`) options.][53003]
81+
- [We now distribute a `rust-gdbgui` script that invokes `gdbgui` with Rust
82+
debug symbols.][53774]
83+
- [Attributes from Rust tools such as `rustfmt` or `clippy` are now
84+
available.][53459] e.g. `#[rustfmt::skip]` will skip formatting the next item.
