Version 0.7 (July 2013)
-----------------------
* ??? changes, numerous bugfixes
* ~2000 changes, numerous bugfixes
* Syntax changes
* Language
* `impl`s no longer accept a visibility qualifier. Put them on methods
instead.
* `use mod` is no longer valid.
* `fail!` and `assert!` accept `~str`, `&'static str` or `fmt!`-style
argument list.
* `Encodable`, `Decodable`, `Ord`, `TotalOrd`, `TotalEq`, `DeepClone`,
`Rand`, `Zero` and `ToStr` can all be automatically derived with
`#[deriving(...)]`.
* The `Durable` trait is replaced with the `'static` bounds.
* At long last, 'argument modes' no longer exist.
* The `bytes!` macro returns a vector of bytes for string, u8, char,
and unsuffixed integer literals.
* `#[static_assert]` makes compile-time assertions about static bools.
* Semantic changes
* The borrow checker has been rewritten with flow-sensitivity, fixing
many bugs and inconveniences.
* The `self` parameter no longer implicitly means `&'self self`,
and can be explicitly marked with a lifetime.
* Structs with the `#[packed]` attribute have byte alignment and
no padding between fields.
* Overloadable compound operators (`+=`, etc.) have been temporarily
removed due to bugs.
* The `for` loop protocol now requires `for`-iterators to return `bool`
so they compose better.
* The `Durable` trait is replaced with the `'static` bounds.
* Trait default methods work more often.
* Structs with the `#[packed]` attribute have byte alignment and
no padding between fields.
* Type parameters bound by `Copy` must now be copied explicitly with
the `copy` keyword.
* It is now illegal to move out of a dereferenced unsafe pointer.
* `Option<~T>` is now represented as a nullable pointer.
* `@mut` does dynamic borrow checks correctly.
* Macros TODO
* The `main` function is only detected at the topmost level of the crate.
The `#[main]` attribute is still valid anywhere.
* Struct fields may no longer be mutable. Use inherited mutability.
* The `#[non_owned]` attribute makes a type that would otherwise be
`Owned`, not. TODO this may change to non_send before 0.7
* The `#[mutable]` attribute makes a type that would otherwise be
`Const`, note. TODO this may change to non_freeze before 0.7
* The `#[no_send]` attribute makes a type that would otherwise be
`Send`, not.
* The `#[no_freeze]` attribute makes a type that would otherwise be
`Freeze`, not.
* Unbounded recursion will abort the process after reaching the limit
specified by the `RUST_MAX_STACK` environment variable (default: 1GB).
* The `vecs_implicitly_copyable` lint mode has been removed. Vectors
are never implicitly copyable.
* `#[static_assert]` makes compile-time assertions about static bools.
* At long last, 'argument modes' no longer exist.
* The rarely used `use mod` statement no longer exists.
* Syntax extensions
* `fail!` and `assert!` accept `~str`, `&'static str` or `fmt!`-style
argument list.
* `Encodable`, `Decodable`, `Ord`, `TotalOrd`, `TotalEq`, `DeepClone`,
`Rand`, `Zero` and `ToStr` can all be automatically derived with
`#[deriving(...)]`.
* The `bytes!` macro returns a vector of bytes for string, u8, char,
and unsuffixed integer literals.
* Libraries
* The `core` crate was renamed to `std`.
* The `std` crate was renamed to `extra`.
* More and improved documentation.
* std: `iterator` module for external iterator objects.
* Many old-style (internal, higher-order function) iterators replaced by
implementations of `Iterator`.
