+
+The Apache Arrow team is pleased to announce the 18.1.0 release. This
+covers roughly one month of development work and includes [**15 resolved
+issues**][1] on [**25 distinct commits**][2] from [**8 distinct
+contributors**][2]. See the [Install Page](https://arrow.apache.org/install/) to
+learn how to get the libraries for your platform.
+
+The primary motivation for this minor release was to address packaging issues
+for Python, Java, C#, R and MATLAB which caused binaries for those platforms to
+report a version of `18.0.0-SNAPSHOT` instead of `18.0.0`. The affected binaries
+were otherwise built correctly. See [this mailing list
+post](https://lists.apache.org/thread/t8k7l2hsbgdt7cszj7hrpjdfpn91n5zb) for more
+details.
+
+The release notes below are not exhaustive and only expose selected
+highlights of the release. Numerous other bugfixes and improvements have been made:
+we refer you to the [complete changelog][3].
+
+## C++ notes
+
+* Moved `ChunkResolver` into the public API. [GH-34535](https://github.com/apache/arrow/issues/34535)
+
+## C# notes
+
+* Fixed [GH-44360](https://github.com/apache/arrow/issues/44360) - [C#] Flight DoExchange server is incompatible with C++/PyArrow client
+
+## Rust and Go notes
+
+The Rust and Go projects have moved to separate repositories outside the
+main Arrow monorepo. For notes on the latest release of the Rust
+implementation, see the latest [Arrow Rust changelog][5].
+For notes on the latest release of the Go implementation, see the latest
+[Arrow Go changelog][6]
