# 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).
## [2.1.0] - 2020-03-26
### ADDED
- There is now a `std` feature flag, on by default, which you can disable to get a `no_std` crate.
## [2.0.0] - 2019-09-09
### CHANGED
- `Bits` now does a lot less work, which is now being done instead by the `BitOps` trait on its
storage type. This turns out to improve compilation time quite considerably. If you were using
methods on `Bits` directly, they will have moved to `BitOps`.
- `Debug` now prints a single hex value for the entire bitmap, rather than deferring to the
storage type.
- `Iter` now takes a reference instead of a copy, which is more sensible for larger bitmaps.
### ADDED
- `Bitmap` now implements `BitAnd`, `BitOr`, `BitXor`, their equivalent assignation traits, and
`Not`, meaning you can now use bitwise operators on them, even the very big array-of-u128 ones.
- A `Bitmap::mask()` constructor has been added, to construct bitmasks more efficiently, now that
there are bitwise operators to use them with.
## [1.0.0] - 2019-09-06
