+## [1.7.1] - 2021-01-17 <a name="1.7.1"></a>
+### Fixed
+- Docs.rs now generates docs for `bytemuck` and `num-traits` optional features.
+
+## [1.7.0] - 2021-01-17 <a name="1.7.0"></a>
+### Added
+- Added optional implementations of `bytemuck` traits `Zeroable` and `Pod` under `bytemuck` cargo
+  feature. By [@charles-r-earp].
+- Added optional implementations of `num-traits` traits `ToPrimitive` and `FromPrimitive` under
+  `num-traits` cargo feature. By [@charles-r-earp].
+- Added implementations of `Binary`, `Octal`, `LowerHex`, and `UpperHex` string format traits to
+  format raw `f16`/`bf16` bytes to string.
+
+### Changed
+- `Debug` trait implementation now formats `f16`/`bf16` as float instead of raw bytes hex. Use newly
+  implemented formatting traits to format in hex instead of `Debug`. Fixes [#37].

-### Allowed failures ###
-
-# See Appveyor documentation for specific details. In short, place any channel or targets you wish
-# to allow build failures on (usually nightly at least is a wise choice). This will prevent a build
-# or test failure in the matching channels/targets from failing the entire build.
-#matrix:
-#  allow_failures:
-#    - channel: nightly
-
-# If you only care about stable channel build failures, uncomment the following line:
-#- channel: beta
-
-## Install Script ##
-
-# This is the most important part of the Appveyor configuration. This installs the version of Rust
-# specified by the 'channel' and 'target' environment variables from the build matrix. This uses
-# rustup to install Rust.
-#
-# For simple configurations, instead of using the build matrix, you can simply set the
-# default-toolchain and default-host manually here.
-install:
-  - appveyor DownloadFile https://win.rustup.rs/ -FileName rustup-init.exe
-  - rustup-init -yv --default-toolchain %channel% --default-host %target%
-  - set PATH=%PATH%;%USERPROFILE%\.cargo\bin
-  - rustc -vV
-  - cargo -vV
-
-## Build Script ##
-
-# 'cargo test' takes care of building for us, so disable Appveyor's build stage. This prevents
-# the "directory does not contain a project or solution file" error.
-build: false
-
-# Uses 'cargo test' to run tests and build. Alternatively, the project may call compiled programs
-#directly or perform other testing commands. Rust will automatically be placed in the PATH
-# environment variable.
-test_script:
-  - cargo test --verbose %cargoflags%
