+Version 0.10 (April 2014)
+-------------------------
+
+ * ~1500 changes, numerous bugfixes
+
+ * Language
+ * A new RFC process is now in place for modifying the language.
+ * Patterns with `@`-pointers have been removed from the language.
+ * Patterns with unique vectors (`~[T]`) have been removed from the
+ language.
+ * Patterns with unique strings (`~str`) have been removed from the
+ language.
+ * `@str` has been removed from the language.
+ * `@[T]` has been removed from the language.
+ * `@self` has been removed from the language.
+ * `@Trait` has been removed from the language.
+ * Headers on `~` allocations which contain `@` boxes inside the type for
+ reference counting have been removed.
+ * The semantics around the lifetimes of temporary expressions have changed,
+ see #3511 and #11585 for more information.
+ * Cross-crate syntax extensions are now possible, but feature gated. See
+ #11151 for more information. This includes both `macro_rules!` macros as
+ well as syntax extensions such as `format!`.
+ * New lint modes have been added, and older ones have been turned on to be
+ warn-by-default.
+ * Unnecessary parentheses
+ * Uppercase statics
+ * Camel Case types
+ * Uppercase variables
+ * Publicly visible private types
+ * `#[deriving]` with raw pointers
+ * Unsafe functions can no longer be coerced to closures.
+ * Various obscure macros such as `log_syntax!` are now behind feature gates.
+ * The `#[simd]` attribute is now behind a feature gate.
+ * Visibility is no longer allowed on `extern crate` statements, and
+ unnecessary visibility (`priv`) is no longer allowed on `use` statements.
+ * Trailing commas are now allowed in argument lists and tuple patterns.
+ * The `do` keyword has been removed, it is now a reserved keyword.
+ * Default type parameters have been implemented, but are feature gated.
+ * Borrowed variables through captures in closures are now considered soundly.
+ * `extern mod` is now `extern crate`
+ * The `Freeze` trait has been removed.
+ * The `Share` trait has been added for types that can be shared among
+ threads.
+ * Labels in macros are now hygienic.
+ * Expression/statement macro invocations can be delimited with `{}` now.
+ * Treatment of types allowed in `static mut` locations has been tweaked.
+ * The `*` and `.` operators are now overloadable through the `Deref` and
+ `DerefMut` traits.
+ * `~Trait` and `proc` no longer have `Send` bounds by default.
+ * Partial type hints are now supported with the `_` type marker.
+ * An `Unsafe` type was introduced for interior mutability. It is now
+ considered undefined to transmute from `&T` to `&mut T` without using the
+ `Unsafe` type.
+ * The #[linkage] attribute was implemented for extern statics/functions.
+ * The inner attribute syntax has changed from `#[foo];` to `#![foo]`.
+ * `Pod` was renamed to `Copy`.
+
+ * Libraries
+ * The `libextra` library has been removed. It has now been decomposed into
+ component libraries with smaller and more focused nuggets of
+ functionality. The full list of libraries can be found on the
+ documentation index page.
+ * std: `std::condition` has been removed. All I/O errors are now propagated
+ through the `Result` type. In order to assist with error handling, a
+ `try!` macro for unwrapping errors with an early return and a lint for
+ unused results has been added. See #12039 for more information.
+ * std: The `vec` module has been renamed to `slice`.
+ * std: A new vector type, `Vec<T>`, has been added in preparation for DST.
+ This will become the only growable vector in the future.
+ * std: `std::io` now has more public-reexports. Types such as `BufferedReader`
+ are now found at `std::io::BufferedReader` instead of
+ `std::io::buffered::BufferedReader`.
+ * std: `print` and `println` are no longer in the prelude, the `print!` and
+ `println!` macros are intended to be used instead.
+ * std: `Rc` now has a `Weak` pointer for breaking cycles, and it no longer
+ attempts to statically prevent cycles.
+ * std: The standard distribution is adopting the policy of pushing failure
+ to the user rather than failing in libraries. Many functions (such as
+ `slice::last()`) now return `Option<T>` instead of `T` + failing.
+ * std: `fmt::Default` has been renamed to `fmt::Show`, and it now has a new
+ deriving mode: `#[deriving(Show)]`.
+ * std: `ToStr` is now implemented for all types implementing `Show`.
+ * std: The formatting trait methods now take `&self` instead of `&T`
+ * std: The `invert()` method on iterators has been renamed to `rev()`
+ * std: `std::num` has seen a reduction in the genericity of its traits,
+ consolidating functionality into a few core traits.
+ * std: Backtraces are now printed on task failure if the environment
+ variable `RUST_BACKTRACE` is present.
+ * std: Naming conventions for iterators have been standardized. More details
+ can be found on the wiki's style guide.
+ * std: `eof()` has been removed from the `Reader` trait. Specific types may
+ still implement the function.
+ * std: Networking types are now cloneable to allow simultaneous reads/writes.
+ * std: `assert_approx_eq!` has been removed
+ * std: The `e` and `E` formatting specifiers for floats have been added to
+ print them in exponential notation.
+ * std: The `Times` trait has been removed
+ * std: Indications of variance and opting out of builtin bounds is done
+ through marker types in `std::kinds::marker` now
+ * std: `hash` has been rewritten, `IterBytes` has been removed, and
+ `#[deriving(Hash)]` is now possible.
+ * std: `SharedChan` has been removed, `Sender` is now cloneable.
+ * std: `Chan` and `Port` were renamed to `Sender` and `Receiver`.
+ * std: `Chan::new` is now `channel()`.
+ * std: A new synchronous channel type has been implemented.
+ * std: A `select!` macro is now provided for selecting over `Receiver`s.
+ * std: `hashmap` and `trie` have been moved to `libcollections`
+ * std: `run` has been rolled into `io::process`
+ * std: `assert_eq!` now uses `{}` instead of `{:?}`
+ * std: The equality and comparison traits have seen some reorganization.
+ * std: `rand` has moved to `librand`.
+ * std: `to_{lower,upper}case` has been implemented for `char`.
+ * std: Logging has been moved to `liblog`.
+ * collections: `HashMap` has been rewritten for higher performance and less
+ memory usage.
+ * native: The default runtime is now `libnative`. If `libgreen` is desired,
+ it can be booted manually. The runtime guide has more information and
+ examples.
+ * native: All I/O functionality except signals has been implemented.
+ * green: Task spawning with `libgreen` has been optimized with stack caching
+ and various trimming of code.
+ * green: Tasks spawned by `libgreen` now have an unmapped guard page.
+ * sync: The `extra::sync` module has been updated to modern rust (and moved
+ to the `sync` library), tweaking and improving various interfaces while
+ dropping redundant functionality.
+ * sync: A new `Barrier` type has been added to the `sync` library.
+ * sync: An efficient mutex for native and green tasks has been implemented.
+ * serialize: The `base64` module has seen some improvement. It treats
+ newlines better, has non-string error values, and has seen general
+ cleanup.
+ * fourcc: A `fourcc!` macro was introduced
+ * hexfloat: A `hexfloat!` macro was implemented for specifying floats via a
+ hexadecimal literal.
+
+ * Tooling
+ * `rustpkg` has been deprecated and removed from the main repository. Its
+ replacement, `cargo`, is under development.
+ * Nightly builds of rust are now available
+ * The memory usage of rustc has been improved many times throughout this
+ release cycle.
+ * The build process supports disabling rpath support for the rustc binary
+ itself.
+ * Code generation has improved in some cases, giving more information to the
+ LLVM optimization passes to enable more extensive optimizations.
+ * Debuginfo compatibility with lldb on OSX has been restored.
+ * The master branch is now gated on an android bot, making building for
+ android much more reliable.
+ * Output flags have been centralized into one `--emit` flag.
+ * Crate type flags have been centralized into one `--crate-type` flag.
+ * Codegen flags have been consolidated behind a `-C` flag.
+ * Linking against outdated crates now has improved error messages.
+ * Error messages with lifetimes will often suggest how to annotate the
+ function to fix the error.
+ * Many more types are documented in the standard library, and new guides
+ were written.
+ * Many `rustdoc` improvements:
+ * code blocks are syntax highlighted.
+ * render standalone markdown files.
+ * the --test flag tests all code blocks by default.
+ * exported macros are displayed.
+ * reexported types have their documentation inlined at the location of the
+ first reexport.
+ * search works across crates that have been rendered to the same output
+ directory.
