# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/) and this project
adheres to [Semantic Versioning](http://semver.org/spec/v2.0.0.html).
## [0.2.6] - 2020-12-19
### ADDED
- `SmartString` now implements `PartialEq<&str>`.
## [0.2.5] - 2020-09-24
### ADDED
- `From` implementations from `Cow<'_, str>` and `&mut str` were added. (#12)
## [0.2.4] - 2020-09-05
### ADDED
- `smartstring` is now `no_std` if you disable the `std` feature flag (which is enabled by
default). (#10)
### FIXED
- `smartstring` will now refuse to compile on 32-bit big-endian architectures, where assuming that
the high bit of a pointer is always empty is going to be a very bad idea.
## [0.2.3] - 2020-07-07
### ADDED
- `SmartString` now implements `Display`. (#6)
- `SmartString` now implements `FromIterator<char>`.
- Support for [`serde`](https://serde.rs/) behind the `serde` feature flag. (#2)
- Support for [`arbitrary`](https://crates.io/crates/arbitrary) behind the `arbitrary` feature
flag.
- Support for [`proptest`](https://crates.io/crates/proptest) behind the `proptest` feature flag.
### FIXED
- `SmartString::push_str` would previously trigger two heap allocations while promoting an inline
string to a boxed string, one of which was unnecessary. It now only makes the one strictly
necessary allocation. (#5)
- Fixed a bug where `SmartString::remove` would panic if you tried to remove the last index in an
inline string.
## [0.2.2] - 2020-07-05
### FIXED
- Calling `shrink_to_fit()` on a string with `LazyCompact` layout will now inline it and
deallocate the heap allocation if the string is short enough to be inlined.
## [0.2.1] - 2020-07-04
### FIXED
- The type alias `smartstring::alias::String` was incorrectly pointing at the `Compact` variant.
It is now pointing at `LazyCompact`, as the documentation describes.
## [0.2.0] - 2020-07-04
### REMOVED
- The `Prefixed` variant has been removed, as it comes with significant code complexity for very
dubious gains.
### CHANGED
- The type alias `smartstring::alias::String` now refers to `LazyCompact` instead of `Compact`,
the idea being that the obvious drop-in replacement for `String` shouldn't have any unexpected
performance differences, which `Compact` can have because it aggressively re-inlines strings to
keep them as local as possible. `LazyCompact` instead heap allocates once when the string is in
excess of the inline capacity and keeps the allocation from then on, so there are no surprises.
### ADDED
- There's a new layout variant, `LazyCompact`, which works like `Compact` except it never
re-inlines strings once they have been moved to the heap.
- As the alias `String` has changed, there is now a new type alias
`smartstring::alias::CompactString`, referring to strings with `Compact` layout.
### FIXED
- Fixed a bug where `SmartString::drain()` would remove twice the drained content from the string.
## [0.1.0] - 2020-05-15
Initial release.
