+
+The Apache Arrow team is pleased to announce the 12.0.0 release. This covers
+over 3 months of development work and includes [**XXX resolved issues**][1]
+from [**YYY distinct contributors**][2]. See the [Install
Page](https://arrow.apache.org/install/)
+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 11.0.0 release, Wang Mingming, Mustafa Akur and Ruihang Xia
+have been invited to be committers.
+Will Jones have joined the Project Management Committee (PMC).
+
+Thanks for your contributions and participation in the project!
+
+## Columnar Format Notes
+
+A first "canonical" extension type has been formalized:
`arrow.fixed_shape_tensor` to
+represent an Array where each slot contains a tensor, with all tensors having
the same
+dimension and shape. This is based on a Fixed-Size List layout as storage array
+(https://arrow.apache.org/docs/dev/format/CanonicalExtensions.html#fixed-shape-tensor-extension).
+
+## Arrow Flight RPC notes
+
+The JDBC driver for Arrow Flight SQL has had some bugfixes, and has been
refactored into a core library (which is not distributed as an uberjar with
shaded names) and a driver (which is distributed as an uberjar).
+
+The Java server builder API now offers easier access to the underlying gRPC
builder.
+
+Go now implements the Flight SQL extensions for Substrait and transaction
support.
+
+## Plasma notes
+
+Plasma was deprecated since 10.0.0. Plasma is removed in this
+release. [GH-33243][GH-33243]
+
+## C++ notes
+
+* Run-End Encoded Arrays have been implemented and are accessible
([GH-32104](https://github.com/apache/arrow/issues/32104))
+* The FixedShapeTensor Logical value type has been implemented using
ExtensionType ([GH-15483](https://github.com/apache/arrow/issues/15483),
[GH-34796](https://github.com/apache/arrow/issues/34796))
+
+### Compute
+
+* New kernel to convert timestamp with timezone to wall time
([GH-33143](https://github.com/apache/arrow/issues/33143))
+* Cast kernels are now built into libarrow by default
([GH-34388](https://github.com/apache/arrow/issues/34388))
+
+### Acero
+
+* Acero has been moved out of libarrow into it's own shared library, allowing
for smaller builds of the core libarrow
([GH-15280](https://github.com/apache/arrow/issues/15280))
+* Exec nodes now can have a concept of "ordering" and will reject non-sensible
plans ([GH-34136](https://github.com/apache/arrow/issues/34136))
+* New exec nodes: "pivot_longer"
([GH-34266](https://github.com/apache/arrow/issues/34266)), "order_by"
([GH-34248](https://github.com/apache/arrow/issues/34248)) and "fetch"
([GH-34059](https://github.com/apache/arrow/issues/34059))
+* Reorder output fields of "group_by" node so that keys/segment keys come
before aggregates ([GH-33616](https://github.com/apache/arrow/issues/33616))
