+The Apache Arrow team is pleased to announce the 9.0.0 release. This covers
+over 3 months of development work and includes [**473 resolved issues**][1]
+from [**YYY 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 8.0.0 release, Dewey Dunnington, Alenka Frim and Rok Mihevc
+have been invited to be committers.
+Thanks for your contributions and participation in the project!
+
+## Columnar Format Notes
+
+## Arrow Flight RPC notes
+
+Arrow Flight is now available in MacOS M1 Python wheels ([ARROW-16779](https://issues.apache.org/jira/browse/ARROW-16779)).
+Arrow Flight SQL is now buildable on Windows ([ARROW-16902](https://issues.apache.org/jira/browse/ARROW-16902)).
+Ruby now exposes more of the Flight and Flight SQL APIs (various JIRAs).
+
+## C++ notes
+
+STL-like iteration is now provided over chunked arrays ([ARROW-602](https://issues.apache.org/jira/browse/ARROW-602)).
+
+### Compute
+
+The C++ compute and execution engine is now officially named "Acero", though
+its C++ namespaces have not changed.
+
+New light-weight data holder abstractions have been introduced in order
Review Comment:
I added some brief notes in https://github.com/apache/arrow-site/pull/227/commits/4fee7a04817245cf4f7c8a9d69444bc128bb4907 but I believe a blog post will eventually also be written.

+## Columnar Format Notes
+
+## Arrow Flight RPC notes
+
+Arrow Flight is now available in MacOS M1 Python wheels ([ARROW-16779](https://issues.apache.org/jira/browse/ARROW-16779)).
+Arrow Flight SQL is now buildable on Windows ([ARROW-16902](https://issues.apache.org/jira/browse/ARROW-16902)).
+Ruby now exposes more of the Flight and Flight SQL APIs (various JIRAs).
+
+## Linux packages notes
+
+AlmaLinux 9 is now supported. ([ARROW-16745](https://issues.apache.org/jira/browse/ARROW-16745))
+
+AmazonLinux 2 aarch64 is now supported. ([ARROW-16477](https://issues.apache.org/jira/browse/ARROW-16477))
+
+## C++ notes
+
+STL-like iteration is now provided over chunked arrays ([ARROW-602](https://issues.apache.org/jira/browse/ARROW-602)).
+
+### Compute
+
+The C++ compute and execution engine is now officially named "Acero", though
+its C++ namespaces have not changed.
+
+New light-weight data holder abstractions have been introduced in order
+to reduce the overhead of invoking compute functions and kernels, especially
+at the small data sizes desirable for efficient parallelization (typically
+L1- or L2-sized). Specifically, the non-owning `ArraySpan` and `ExecSpan`
+structures have internally superseded the much heavier `ExecBatch`, which
+is still supported for compatibility at the API level
+([ARROW-16756](https://issues.apache.org/jira/browse/ARROW-16756), [ARROW-16824](https://issues.apache.org/jira/browse/ARROW-16824), [ARROW-16852](https://issues.apache.org/jira/browse/ARROW-16852)).
+
+In a similar vein, the `ValueDescr` class was removed and `ScalarKernel`
+implementations now always receive at least one non-scalar input, removing
+the special case where a `ScalarKernel` needs to output a scalar rather than
+an array. The higher-level compute APIs still allow executing a scalar function
+over all-scalar inputs; but those scalars are internally broadcasted to
+1-element arrays so as to simplify kernel implementation ([ARROW-16757](https://issues.apache.org/jira/browse/ARROW-16757)).
