+
+The Apache Arrow team is pleased to announce the 0.7.0 release of
+Apache Arrow nanoarrow. This release covers 117 resolved issues from
+12 contributors.
+
+## Release Highlights
+
+- Migrate Python bindings to Meson Python
+- Better support for shared linkage
+- ZSTD Decompression support in IPC reader
+- Decimal32, Decimal64, ListView and LargeListView support
+- Support for vcpkg
+
+See the
+[Changelog](https://github.com/apache/arrow-nanoarrow/blob/apache-arrow-nanoarrow-0.7.0-rc1/CHANGELOG.md)
+for a detailed list of contributions to this release.
+
+## Features
+
+### Meson Python
+
+The Python bindings now use [Meson
Python](https://mesonbuild.com/meson-python/) as
+the build backend. The main benefit is that adding C or C++ library
dependencies
+like ZSTD is much simpler than with setuptools which was needed to add the new
+decompression support to the Python bindings.
+
+Thanks to [@WillAyd](https://github.com/WillAyd) for this contribution and
continued
+maintenance of the Python build infrastructure!
+
+### Shared Linkage
+
+The nanoarrow C library is generally designed to be statically linked into an
+application or library; however, there were some applications that did want
+shared linkage and on Windows some extra work was needed to ensure this worked
+as intended. Version 0.7.0 includes the appropriate DLL import/export
attributes
+and adds dedicated `nanoarrow_shared` and `nanoarrow_static` targets to the
CMake
+configuration to explicitly choose a strategy (linking to `nanoarrow` will
continue
+to use the CMake default as it did in previous versions).
+
+Thanks to [@m-kuhn](https://github.com/m-kuhn) for authoring the initial vcpkg
+configuration that brought this to our attention!
+
+### ZSTD Decompression Support
+
+The Arrow IPC reader included in the nanoarrow C library supports most features
+of the Arrow IPC format; however, decompression support was missing which made
+the library and its bindings unusable for some common use cases. In 0.7.0,
+decompression support was added to the C library and R and Python bindings.

+
+Users of the C library will need to configure CMake with
`-DNANOARROW_IPC_WITH_ZSTD=ON`
+and `-DNANOARROW_IPC=ON` to use CMake-resolved ZSTD; however, client libraries
+can also use an existing ZSTD or LZ4 implementation using callbacks.
+
+### New Type Support
+
+While the nanoarrow C library is a minimal library, we do strive to support
the full
+specification and several new types were not supported by the C library.
Version 0.7.0
+includes support in the C library for Decimal32, Decimal64, ListView, and
LargeListView
+and improved support for support for decimal types in the nanoarrow R bindings.
+
+Thanks to [@zeroshade](https://github.com/zeroshade) for contributing
Decimal32/Decimal64
+support and [@WillAyd](https://github.com/WillAyd) for contributing
+
+### nanoarrow on vcpkg
+
+The nanoarrow C library can now be installed using
+[vcpkg](https://github.com/microsoft/vcpkg)!
+
+```shell
+git clone https://github.com/microsoft/vcpkg.git
+cd vcpkg && ./bootstrap-vcpkg.sh
+./vcpkg install nanoarrow
+```
+
+CMake projects can then use `find_package(nanoarrow)` when using the vcpkg
+toolchain (i.e.,
`-DCMAKE_TOOLCHAIN_FILE=path/to/vcpkg/scripts/buildsystems/vcpkg.cmake`).
+This also allows other vcpkg ports to use nanoarrow as a dependency in addition
+to a convenience for projects already using vcpkg.
+
+Thanks to [@m-kuhn](https://github.com/m-kuhn) for contributing the nanoarrow
port to
+vcpkg!
+
+## Contributors
+
+This release consists of contributions from 12 contributors in addition
+to the invaluable advice and support of the Apache Arrow community.
