3 | | - |
4 | | - * ~2100 changes, numerous bugfixes |
5 | | - |
6 | | - * Language |
7 | | - * The `for` loop syntax has changed to work with the `Iterator` trait. |
8 | | - * At long last, unwinding works on Windows. |
9 | | - * Default methods definitely mostly work. |
10 | | - * Many trait inheritance bugs fixed. |
11 | | - * Owned and borrowed trait objects work more reliably. |
12 | | - * `copy` is no longer a keyword. It has been replaced by the `Clone` trait. |
13 | | - * rustc no longer emits code for the `debug!` macro unless it is passed |
14 | | - `--cfg debug` |
15 | | - * mod.rs is now "blessed". When loading `mod foo;`, rustc will now look |
16 | | - for foo.rs, then foo/mod.rs, and will generate an error when both are |
17 | | - present. |
18 | | - * Strings no longer contain trailing nulls. The new `std::c_str` module |
19 | | - provides new mechanisms for converting to C strings. |
20 | | - * The type of foreign functions is now `extern "C" fn` instead of `*u8'. |
21 | | - * The FFI has been overhauled such that foreign functions are called directly, |
22 | | - instead of through a stack-switching wrapper. |
23 | | - * Calling a foreign function must be done through a Rust function with the |
24 | | - `#[fixed_stack_segment]` attribute. |
25 | | - * The `externfn!` macro can be used to declare both a foreign function and |
26 | | - a `#[fixed_stack_segment]` wrapper at once. |
27 | | - * `pub` and `priv` modifiers on `extern` blocks are no longer parsed. |
28 | | - * `unsafe` is no longer allowed on extern fns - they are all unsafe. |
29 | | - * `priv` is disallowed everywhere except for struct fields and enum variants. |
30 | | - * `&T` (besides `&'static T`) is no longer allowed in `@T`. |
31 | | - * `ref` bindings in irrefutable patterns work correctly now. |
32 | | - * `char` is now prevented from containing invalid code points. |
33 | | - * Casting to `bool` is no longer allowed. |
34 | | - * `yield` is a reserved keyword. |
35 | | - * `typeof` is a reserved keyword. |
36 | | - * Crates may be imported by URL with `extern mod foo = "url";`. |
37 | | - * Explicit enum discriminants may be given as uints as in `enum E { V = 0u }` |
38 | | - * Static vectors can be initialized with repeating elements, |
39 | | - e.g. `static foo: [u8, .. 100]: [0, .. 100];`. |
40 | | - * Static structs can be initialized with functional record update, |
41 | | - e.g. `static foo: Foo = Foo { a: 5, .. bar };`. |
42 | | - * `cfg!` can be used to conditionally execute code based on the crate |
43 | | - configuration, similarly to `#[cfg(...)]`. |
44 | | - * The `unnecessary_qualification` lint detects unneeded module |
45 | | - prefixes (default: allow). |
46 | | - * Arithmetic operations have been implemented on the SIMD types in |
47 | | - `std::unstable::simd`. |
48 | | - * Exchange allocation headers were removed, reducing memory usage. |
49 | | - * `format!` implements a completely new, extensible, and higher-performance |
50 | | - string formatting system. It will replace `fmt!`. |
51 | | - * `print!` and `println!` write formatted strings (using the `format!` |
52 | | - extension) to stdout. |
53 | | - * `write!` and `writeln!` write formatted strings (using the `format!` |
54 | | - extension) to the new Writers in `std::rt::io`. |
55 | | - * The library section in which a function or static is placed may |
56 | | - be specified with `#[link_section = "..."]`. |
57 | | - * The `proto!` syntax extension for defining bounded message protocols |
58 | | - was removed. |
59 | | - * `macro_rules!` is hygenic for `let` declarations. |
60 | | - * The `#[export_name]` attribute specifies the name of a symbol. |
61 | | - * `unreachable!` can be used to indicate unreachable code, and fails |
62 | | - if executed. |
63 | | - |
64 | | - * Libraries |
65 | | - * std: Transitioned to the new runtime, written in Rust. |
66 | | - * std: Added an experimental I/O library, `rt::io`, based on the new |
67 | | - runtime. |
68 | | - * std: A new generic `range` function was added to the prelude, replacing |
69 | | - `uint::range` and friends. |
70 | | - * std: `range_rev` no longer exists. Since range is an iterator it can be |
71 | | - reversed with `range(lo, hi).invert()`. |
72 | | - * std: The `chain` method on option renamed to `and_then`; `unwrap_or_default` |
73 | | - renamed to `unwrap_or`. |
74 | | - * std: The `iterator` module was renamed to `iter`. |
75 | | - * std: Integral types now support the `checked_add`, `checked_sub`, and |
76 | | - `checked_mul` operations for detecting overflow. |
77 | | - * std: Many methods in `str`, `vec`, `option, `result` were renamed for |
78 | | - consistency. |
79 | | - * std: Methods are standardizing on conventions for casting methods: |
80 | | - `to_foo` for copying, `into_foo` for moving, `as_foo` for temporary |
81 | | - and cheap casts. |
82 | | - * std: The `CString` type in `c_str` provides new ways to convert to and |
83 | | - from C strings. |
84 | | - * std: `DoubleEndedIterator` can yield elements in two directions. |
85 | | - * std: The `mut_split` method on vectors partitions an `&mut [T]` into |
86 | | - two splices. |
87 | | - * std: `str::from_bytes` renamed to `str::from_utf8`. |
88 | | - * std: `pop_opt` and `shift_opt` methods added to vectors. |
89 | | - * std: The task-local data interface no longer uses @, and keys are |
90 | | - no longer function pointers. |
91 | | - * std: The `swap_unwrap` method of `Option` renamed to `take_unwrap`. |
92 | | - * std: Added `SharedPort` to `comm`. |
93 | | - * std: `Eq` has a default method for `ne`; only `eq` is required |
94 | | - in implementations. |
95 | | - * std: `Ord` has default methods for `le`, `gt` and `le`; only `lt` |
96 | | - is required in implementations. |
97 | | - * std: `is_utf8` performance is improved, impacting many string functions. |
98 | | - * std: `os::MemoryMap` provides cross-platform mmap. |
99 | | - * std: `ptr::offset` is now unsafe, but also more optimized. Offsets that |
100 | | - are not 'in-bounds' are considered undefined. |
101 | | - * std: Many freestanding functions in `vec` removed in favor of methods. |
102 | | - * std: Many freestanding functions on scalar types removed in favor of |
103 | | - methods. |
104 | | - * std: Many options to task builders were removed since they don't make |
105 | | - sense in the new scheduler design. |
106 | | - * std: More containers implement `FromIterator` so can be created by the |
107 | | - `collect` method. |
108 | | - * std: More complete atomic types in `unstable::atomics`. |
109 | | - * std: `comm::PortSet` removed. |
110 | | - * std: Mutating methods in the `Set` and `Map` traits have been moved into |
111 | | - the `MutableSet` and `MutableMap` traits. `Container::is_empty`, |
112 | | - `Map::contains_key`, `MutableMap::insert`, and `MutableMap::remove` have |
113 | | - default implementations. |
114 | | - * extra: `dlist`, the doubly-linked list was modernized. |
115 | | - * extra: Added a `hex` module with `ToHex` and `FromHex` traits. |
116 | | - * extra: Added `glob` module, replacing `std::os::glob`. |
117 | | - * extra: `rope` was removed. |
118 | | - * extra: `deque` was renamed to `ringbuf`. `RingBuf` implements `Deque`. |
119 | | - * extra: `net`, and `timer` were removed. The experimental replacements |
120 | | - are `std::rt::io::net` and `std::rt::io::timer`. |
121 | | - * extra: Iterators implemented for `SmallIntMap`. |
122 | | - * extra: Iterators implemented for `Bitv` and `BitvSet`. |
123 | | - * extra: `SmallIntSet` removed. Use `BitvSet`. |
124 | | - * extra: Performance of JSON parsing greatly improved. |
125 | | - * extra: `semver` updated to SemVer 2.0.0. |
126 | | - * extra: `term` handles more terminals correctly. |
127 | | - * extra: `dbg` module removed. |
128 | | - |
129 | | - * Other |
130 | | - * rustc's debug info generation (`-Z debug-info`) is greatly improved. |
131 | | - * rustc accepts `--target-cpu` to compile to a specific CPU architecture, |
132 | | - similarly to gcc's `--march` flag. |
133 | | - * rustpkg has received many improvements. |
134 | | - * rustpkg supports git tags as package IDs. |
135 | | - * rustpkg builds into target-specific directories so it can be used for |
136 | | - cross-compiling. |
137 | | - * The number of concurrent test tasks is controlled by the environment |
138 | | - variable RUST_TEST_TASKS. |
139 | | - * The test harness can now report metrics for benchmarks. |
140 | | - * All tools have man pages. |
141 | | - * Programs compiled with `--test` now support the `-h` and `--help` flags. |
142 | | - * The runtime uses jemalloc for allocations. |
143 | | - * Segmented stacks are temporarily disabled as part of the transition to |
144 | | - the new runtime. Stack overflows are possible! |
