+The Apache Arrow team is pleased to announce the 4.0.0 release. This covers
+3 months of development work and includes [**711 resolved issues**][1]
+from [**114 distinct contributors**][2]. See the Install Page to learn how to
+get the libraries for your platform.
+
+The release notes below are not exhaustive and only expose selected highlights
+of the release. Many other bugfixes and improvements have been made: we refer
+you to the [complete changelog][3].
+
+## Community
+
+Since the 3.0.0 release, Yibo Cai has been invited as a committer to Arrow, and Andrew Lamb and Jorge Leitão have joined the Project Management Committee (PMC). Thank you for all of your contributions!
+
+## Columnar Format Notes
+
+## Arrow Flight RPC notes
+
+In Java, applications can now enable zero-copy optimizations when writing data (ARROW-11066). This potentially breaks source compatibility, so it is not enabled by default.
+
+Arrow Flight is now packaged for C#/.NET.
+## C++ notes
+
+The Arrow C++ library now includes a [`vcpkg.json`](https://github.com/apache/arrow/blob/master/cpp/vcpkg.json) manifest file and a new CMake option `-DARROW_DEPENDENCY_SOURCE=VCPKG` to simplify installation of dependencies using the [vcpkg](https://github.com/microsoft/vcpkg) package manager. This provides an alternative means of installing C++ library dependencies on Linux, macOS, and Windows. See the [Building Arrow C++](https://arrow.apache.org/docs/developers/cpp/building.html) and [Developing on Windows](https://arrow.apache.org/docs/developers/cpp/windows.html) docs pages for details.

Review comment:
```suggestion
Java now supports IPC buffer compression (ZSTD is recommended as the current performance of LZ4 is quite slow).
