+
+The Apache Arrow team is pleased to announce the 0.8.0 release of
+Apache Arrow nanoarrow. This release consists of 28 resolved GitHub issues from
+10 contributors.
+
+## Release Highlights
+
+- Support for building String View arrays by buffer
+- LZ4 decompression support in IPC reader
+- Support for Conan
+- Support for Hombrew
+
+See the
+[Changelog](https://github.com/apache/arrow-nanoarrow/blob/apache-arrow-nanoarrow-0.8.0/CHANGELOG.md)
+for a detailed list of contributions to this release.
+
+## Features
+
+### String Views By Buffer
+
+The C library in general supports two methods for producing or consuming arrays: most
+users use the builder pattern (e.g., `ArrowArrayAppendString()`); however, the "build
+by buffer" pattern can be effective when using nanoarrow with a higher level runtime
+like C++, Rust, Python, or R, all of which have mechanisms to build buffers already.
+The C library supports this with `ArrowArraySetBuffer()`; however, there was no way
+to reserve and/or set variadic buffers for string view arrays. In nanoarrow 0.8.0,
+the array builder API fully supports both mechanisms for building string view arrays.
+
+### LZ4 Decompression Support
+
+The Arrow IPC reader included in the nanoarrow C library supports most features
+of the Arrow IPC format; however, decompression support for the LZ4 codec was missing
+which made the library and its bindings unusable for some common use cases. In 0.8.0,
+decompression for the LZ4 codec was added to the C library.
+
+Users of the C library will need to configure CMake with `-DNANOARROW_IPC_WITH_LZ4=ON`
+and `-DNANOARROW_IPC=ON` to use CMake-resolved LZ4; however, client libraries
+can also use an existing ZSTD or LZ4 implementation using callbacks just like in 0.7.0.
+
+### nanoarrow on Conan
+
+The nanoarrow C library can now be installed using the
+[Conan](https://conan.io/center/recipes/nanoarrow) C/C++ Package Manager!
+CMake projects can now use `find_package(nanoarrow)` when using a Conan-enabled
+toolchain after adding the nanoarrow dependency to `conanfile.txt`.
+
+Thanks to [@wgtmac](https://github.com/wgtmac) for contributing the recipe!
+
+### nanoarrow on Homebrew
+
+The nanoarrow C library can now be installed using
+[Homebrew](https://formulae.brew.sh/formula/nanoarrow)!
+
+```shell
+brew install nanoarrow
+```
+
+CMake projects can then use `find_package(nanoarrow)` when using Homebrew-provided
+cmake and allows other vcpkg ports to use nanoarrow as a dependency.
+
+Thanks to [@ankane](https://github.com/ankane) for contributing the formula!
