+## Unreleased
+
+# 0.10.2 – 2023-02-25
+
+- Add `#[track_caller]` to methods ([#27](https://github.com/phil-opp/rust-bit-field/pull/27))
+
+# 0.10.1 – 2020-08-23
+
+- Added bit manipulation functions for 128-bit integers ([#24](https://github.com/phil-opp/rust-bit-field/pull/24))
+
+## [0.10.0] - 2019-05-03
+### Added
+ - Support all range types (`Range`, `RangeInclusive`, `RangeFrom`, …) for `get_bits` and `set_bits` methods ([#22](https://github.com/phil-opp/rust-bit-field/pull/22))
+
+### Changed
+ - **Breaking**: `BitField` trait now has a `BIT_LENGTH` associated const instead of a `bit_length` associated function.
+ - `BitField` and `BitArray` methods are now inlined which causes much higher performance.
+
+## [0.9.0] - 2017-10-15
+### Changed
+ - Bit indexes in `BitField` is now `usize` instead of `u8`.
+
+## [0.8.0] - 2017-07-16
+### Added
+ - `BitArray` trait to make bit indexing possible with slices.
+### Changed
+ - `bit_length` in `BitField` is now an associated function instead of a method (`bit_length()` instead of `bit_length(&self)`)
+
+## [0.7.0] - 2017-01-16
+### Added
+ - `BitField` was also implemented for: `i8`, `i16`, `i32`, `i64` and `isize`
+### Changed
+ - `length()` method in `BitField` is now called `bit_length()`
+ - `get_range()` method in `BitField` is now called `get_bits()`
+ - `set_range()` method in `BitField` is now called `set_bits()`
+### Removed
+ - `zero()` and `one()` constructor was removed from `BitField` trait.

+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.

+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,

+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+# bit_field
+
+A simple crate which provides the `BitField` trait, which provides methods for operating on individual bits and ranges
+of bits on Rust's integral types.
+
+## Documentation
+Documentation is available on [docs.rs](https://docs.rs/bit_field)
+
+## Usage
+```TOML
+[dependencies]
+bit_field = "0.10.1"
+```
+
+## Example
+```rust
+extern crate bit_field;
+use bit_field::BitField;
+
+let mut x: u8 = 0;
+
+x.set_bit(7, true);
+assert_eq!(x, 0b1000_0000);
+
+x.set_bits(0..4, 0b1001);
+assert_eq!(x, 0b1000_1001);
+
+```
