|
4 | | - * ~1600 changes, numerous bugfixes |
5 | | - |
6 | | - * Language |
7 | | - * The `float` type has been removed. Use `f32` or `f64` instead. |
8 | | - * A new facility for enabling experimental features (feature gating) has |
9 | | - been added, using the crate-level `#[feature(foo)]` attribute. |
10 | | - * Managed boxes (@) are now behind a feature gate |
11 | | - (`#[feature(managed_boxes)]`) in preperation for future removal. Use the |
12 | | - standard library's `Gc` or `Rc` types instead. |
13 | | - * `@mut` has been removed. Use `std::cell::{Cell, RefCell}` instead. |
14 | | - * Jumping back to the top of a loop is now done with `continue` instead of |
15 | | - `loop`. |
16 | | - * Strings can no longer be mutated through index assignment. |
17 | | - * Raw strings can be created via the basic `r"foo"` syntax or with matched |
18 | | - hash delimiters, as in `r###"foo"###`. |
19 | | - * `~fn` is now written `proc (args) -> retval { ... }` and may only be |
20 | | - called once. |
21 | | - * The `&fn` type is now written `|args| -> ret` to match the literal form. |
22 | | - * `@fn`s have been removed. |
23 | | - * `do` only works with procs in order to make it obvious what the cost |
24 | | - of `do` is. |
25 | | - * The `#[link(...)]` attribute has been replaced with |
26 | | - `#[crate_id = "name#vers"]`. |
27 | | - * Empty `impl`s must be terminated with empty braces and may not be |
28 | | - terminated with a semicolon. |
29 | | - * Keywords are no longer allowed as lifetime names; the `self` lifetime |
30 | | - no longer has any special meaning. |
31 | | - * The old `fmt!` string formatting macro has been removed. |
32 | | - * `printf!` and `printfln!` (old-style formatting) removed in favor of |
33 | | - `print!` and `println!`. |
34 | | - * `mut` works in patterns now, as in `let (mut x, y) = (1, 2);`. |
35 | | - * New reserved keywords: `alignof`, `offsetof`, `sizeof`. |
36 | | - * Macros can have attributes. |
37 | | - * Macros can expand to items with attributes. |
38 | | - * Macros can expand to multiple items. |
39 | | - * The `asm!` macro is feature-gated (`#[feature(asm)]`). |
40 | | - * Comments may be nested. |
41 | | - * Values automatically coerce to trait objects they implement, without |
42 | | - an explicit `as`. |
43 | | - * Enum discriminants are no longer an entire word but as small as needed to |
44 | | - contain all the variants. The `repr` attribute can be used to override |
45 | | - the discriminant size, as in `#[repr(int)]` for integer-sized, and |
46 | | - `#[repr(C)]` to match C enums. |
47 | | - * Non-string literals are not allowed in attributes (they never worked). |
48 | | - * The FFI now supports variadic functions. |
49 | | - * Octal numeric literals, as in `0o7777`. |
50 | | - * The `concat!` syntax extension performs compile-time string concatenation. |
51 | | - * The `#[fixed_stack_segment]` and `#[rust_stack]` attributes have been |
52 | | - removed as Rust no longer uses segmented stacks. |
53 | | - * Non-ascii identifiers are feature-gated (`#[feature(non_ascii_idents)]`). |
54 | | - * Ignoring all fields of an enum variant or tuple-struct is done with `..`, |
55 | | - not `*`; ignoring remaining fields of a struct is also done with `..`, |
56 | | - not `_`; ignoring a slice of a vector is done with `..`, not `.._`. |
57 | | - * `rustc` supports the "win64" calling convention via `extern "win64"`. |
58 | | - * `rustc` supports the "system" calling convention, which defaults to the |
59 | | - preferred convention for the target platform, "stdcall" on 32-bit Windows, |
60 | | - "C" elsewhere. |
61 | | - * The `type_overflow` lint (default: warn) checks literals for overflow. |
62 | | - * The `unsafe_block` lint (default: allow) checks for usage of `unsafe`. |
63 | | - * The `attribute_usage` lint (default: warn) warns about unknown |
64 | | - attributes. |
65 | | - * The `unknown_features` lint (default: warn) warns about unknown |
66 | | - feature gates. |
67 | | - * The `dead_code` lint (default: warn) checks for dead code. |
68 | | - * Rust libraries can be linked statically to one another |
69 | | - * `#[link_args]` is behind the `link_args` feature gate. |
70 | | - * Native libraries are now linked with `#[link(name = "foo")]` |
71 | | - * Native libraries can be statically linked to a rust crate |
72 | | - (`#[link(name = "foo", kind = "static")]`). |
73 | | - * Native OS X frameworks are now officially supported |
74 | | - (`#[link(name = "foo", kind = "framework")]`). |
75 | | - * The `#[thread_local]` attribute creates thread-local (not task-local) |
76 | | - variables. Currently behind the `thread_local` feature gate. |
77 | | - * The `return` keyword may be used in closures. |
78 | | - * Types that can be copied via a memcpy implement the `Pod` kind. |
79 | | - |
80 | | - * Libraries |
81 | | - * std: The `option` and `result` API's have been overhauled to make them |
82 | | - simpler, more consistent, and more composable. |
83 | | - * std: The entire `std::io` module has been replaced with one that is |
84 | | - more comprehensive and that properly interfaces with the underlying |
85 | | - scheduler. File, TCP, UDP, Unix sockets, pipes, and timers are all |
86 | | - implemented. |
87 | | - * std: `io::util` contains a number of useful implementations of |
88 | | - `Reader` and `Writer`, including `NullReader`, `NullWriter`, |
89 | | - `ZeroReader`, `TeeReader`. |
90 | | - * std: The reference counted pointer type `extra::rc` moved into std. |
91 | | - * std: The `Gc` type in the `gc` module will replace `@` (it is currently |
92 | | - just a wrapper around it). |
93 | | - * std: `fmt::Default` can be implemented for any type to provide default |
94 | | - formatting to the `format!` macro, as in `format!("{}", myfoo)`. |
95 | | - * std: The `rand` API continues to be tweaked. |
96 | | - * std: Functions dealing with type size and alignment have moved from the |
97 | | - `sys` module to the `mem` module. |
98 | | - * std: The `path` module was written and API changed. |
99 | | - * std: `str::from_utf8` has been changed to cast instead of allocate. |
100 | | - * std: `starts_with` and `ends_with` methods added to vectors via the |
101 | | - `ImmutableEqVector` trait, which is in the prelude. |
102 | | - * std: Vectors can be indexed with the `get_opt` method, which returns `None` |
103 | | - if the index is out of bounds. |
104 | | - * std: Task failure no longer propagates between tasks, as the model was |
105 | | - complex, expensive, and incompatible with thread-based tasks. |
106 | | - * std: The `Any` type can be used for dynamic typing. |
107 | | - * std: `~Any` can be passed to the `fail!` macro and retrieved via |
108 | | - `task::try`. |
109 | | - * std: Methods that produce iterators generally do not have an `_iter` |
110 | | - suffix now. |
111 | | - * std: `cell::Cell` and `cell::RefCell` can be used to introduce mutability |
112 | | - roots (mutable fields, etc.). Use instead of e.g. `@mut`. |
113 | | - * std: `util::ignore` renamed to `prelude::drop`. |
114 | | - * std: Slices have `sort` and `sort_by` methods via the `MutableVector` |
115 | | - trait. |
116 | | - * std: `vec::raw` has seen a lot of cleanup and API changes. |
117 | | - * std: The standard library no longer includes any C++ code, and very |
118 | | - minimal C, eliminating the dependency on libstdc++. |
119 | | - * std: Runtime scheduling and I/O functionality has been factored out into |
120 | | - extensible interfaces and is now implemented by two different crates: |
121 | | - libnative, for native threading and I/O; and libgreen, for green threading |
122 | | - and I/O. This paves the way for using the standard library in more limited |
123 | | - embeded environments. |
124 | | - * std: The `comm` module has been rewritten to be much faster, have a |
125 | | - simpler, more consistent API, and to work for both native and green |
126 | | - threading. |
127 | | - * std: All libuv dependencies have been moved into the rustuv crate. |
128 | | - * native: New implementations of runtime scheduling on top of OS threads. |
129 | | - * native: New native implementations of TCP, UDP, file I/O, process spawning, |
130 | | - and other I/O. |
131 | | - * green: The green thread scheduler and message passing types are almost |
132 | | - entirely lock-free. |
133 | | - * extra: The `flatpipes` module had bitrotted and was removed. |
134 | | - * extra: All crypto functions have been removed and Rust now has a policy of |
135 | | - not reimplementing crypto in the standard library. In the future crypto |
136 | | - will be provided by external crates with bindings to established libraries. |
137 | | - * extra: `c_vec` has been modernized. |
138 | | - * extra: The `sort` module has been removed. Use the `sort` method on |
139 | | - mutable slices. |
| 4 | + * ~XXX changes, numerous bugfixes |
140 | 5 |
|
141 | 6 | * Tooling |
142 | | - * The `rust` and `rusti` commands have been removed, due to lack of |
143 | | - maintenance. |
144 | | - * `rustdoc` was completely rewritten. |
145 | | - * `rustdoc` can test code examples in documentation. |
146 | | - * `rustpkg` can test packages with the argument, 'test'. |
147 | | - * `rustpkg` supports arbitrary dependencies, including C libraries. |
148 | | - * `rustc`'s support for generating debug info is improved again. |
149 | | - * `rustc` has better error reporting for unbalanced delimiters. |
150 | | - * `rustc`'s JIT support was removed due to bitrot. |
151 | | - * Executables and static libraries can be built with LTO (-Z lto) |
152 | | - * `rustc` adds a `--dep-info` flag for communicating dependencies to |
153 | | - build tools. |
| 7 | + * The `rust` and `rusti` commands have been removed, due to lack of maintenance. |
