The core library defines common types and traits but\n+  has no platform dependencies whatsoever, and is the basis for Rust\n+  software in environments that cannot support a full port of the\n+  standard library, such as operating systems. Most of the core\n+  library is now stable.\n+\n+Libraries\n+---------\n+\n+* Stabilized APIs:\n+  [`Read::read_exact`], [`ErrorKind::UnexpectedEof`] (renamed from\n+  `UnexpectedEOF`), [`fs::DirBuilder`], [`fs::DirBuilder::new`],\n+  [`fs::DirBuilder::recursive`], [`fs::DirBuilder::create`],\n+  [`os::unix::fs::DirBuilderExt`],\n+  [`os::unix::fs::DirBuilderExt::mode`], [`vec::Drain`],\n+  [`vec::Vec::drain`], [`string::Drain`], [`string::String::drain`],\n+  [`vec_deque::Drain`], [`vec_deque::VecDeque::drain`],\n+  [`collections::hash_map::Drain`],\n+  [`collections::hash_map::HashMap::drain`],\n+  [`collections::hash_set::Drain`],\n+  [`collections::hash_set::HashSet::drain`],\n+  [`collections::binary_heap::Drain`],\n+  [`collections::binary_heap::BinaryHeap::drain`],\n+  [`Vec::extend_from_slice`] (renamed from `push_all`),\n+  [`Mutex::get_mut`], [`Mutex::into_inner`], [`RwLock::get_mut`],\n+  [`RwLock::into_inner`], [`Iterator::min_by_key`] (renamed from\n+  `min_by`), [`Iterator::max_by_key`] (renamed from `max_by`).\n+* The [core library][1.6co] is stable, as are most of its APIs.\n+* [The `assert_eq!` macro supports arguments that don't implement\n+  `Sized`][1.6ae], such as arrays. In this way it behaves more like\n+  `assert!`.\n+* Several timer functions that take duration in milliseconds [are\n+  deprecated in favor of those that take `Duration`][1.6ms]. These\n+  include `Condvar::wait_timeout_ms`, `thread::sleep`, and\n+  `thread_park_timeout_ms`.\n+* The algorithm by which `Vec` reserves additional elements was\n+  [tweaked to not allocate excessive space][1.6a] while still growing\n+  exponentially.\n+* `From` conversions are [implemented from integers to floats][1.6f]\n+  in cases where the conversion is lossless. Thus they are not\n+  implemented for 32-bit ints to `f64`, nor for 64-bit ints.
