# 0.5.6 (July 13, 2020)
|
||||
|
||||
- Improve `BytesMut` to reuse buffer when fully `advance`d.
|
||||
- Mark `BytesMut::{as_mut, set_len}` with `#[inline]`.
|
||||
- Relax synchronization when cloning in shared vtable of `Bytes`.
|
||||
- Move `loom` to `dev-dependencies`.
|
||||
|
||||
# 0.5.5 (June 18, 2020)
|
||||
|
||||
### 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 `advance`d (#352).
|
||||
|
||||
# 0.5.4 (January 23, 2020)
|
||||
|
||||
### 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.
|
||||
|
||||
