v0.5.6

• Improve BytesMut to reuse buffer when fully advanced.
• Mark BytesMut::{as_mut, set_len} with #[inline].
• Relax synchronization when cloning in shared vtable of Bytes.
• Move loom to dev-dependencies.

v0.5.5

Added

• Allow using the serde feature in no_std environments (#385).

Fix

• Fix BufMut::advance_mut to panic if advanced passed the capacity (#354)..
• Fix BytesMut::freeze ignoring amount previously advanced (#352).

v0.5.4

Added

• Make Bytes::new a const fn.
• Add From<BytesMut> for Bytes.

Fix

• Fix reversed arguments in PartialOrd for Bytes.
• Fix Bytes::truncate losing original capacity when repr is an unshared Vec.
• Fix Bytes::from(Vec) when allocator gave Vec a pointer with LSB set.
• Fix panic in Bytes::slice_ref if argument is an empty slice.

v0.5.3

Added

• must_use attributes to split, split_off, and split_to methods (#337).

Fix

• Potential freeing of a null pointer in Bytes when constructed with an empty Vec<u8> (#341, #342).
• Calling Bytes::truncate with a size large than the length will no longer clear the Bytes (#333).

v0.5.2

Added

• Limit methods into_inner, get_ref, get_mut, limit, and set_limit (#325).

v0.5.1

Fix

• Growth documentation for BytesMut (#321)

v0.5.0

Fix

• Potential overflow in copy_to_slice

Changed

• Increased minimum supported Rust version to 1.39.
• Bytes is now a "trait object", allowing for custom allocation strategies (#298)
• BytesMut implicitly grows internal storage. remaining_mut() returns
  usize::MAX (#316).
• BufMut::bytes_mut returns &mut [MaybeUninit<u8>] to reflect the unknown
  initialization state (#305).
• Buf / BufMut implementations for &[u8] and &mut [u8]
  respectively (#261).
• Move Buf / BufMut "extra" functions to an extension trait (#306).
• BufMutExt::limit (#309).
• Bytes::slice takes a RangeBounds argument (#265).
• Bytes::from_static is now a const fn (#311).
• A multitude of smaller performance optimizations.

Added

• no_std support (#281).
• get_*, put_*, get_*_le, and put_*le accessors for handling byte order.
• BorrowMut implementation for BytesMut (#185).

Removed

• IntoBuf (#288).
• Buf implementation for &str (#301).
• byteorder dependency (#280).
• iovec dependency, use std::IoSlice instead (#263).
• optional either dependency (#315).
• optional i128 feature -- now available on stable. (#276).
