+The Apache Arrow team is pleased to announce the 14.0.0 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 13.0.0 release, Metehan Yildirim and Oleks V. have been invited to
be committers.
+
+Thanks for your contributions and participation in the project!
+
+## Columnar Format Notes
+
+A `VariableShapeTensorType` was added to the Arrow specification as a
canonical extension type.
([GH-24868](https://github.com/apache/arrow/issues/24868)).
+
+Motivated by recent innovations in DuckDB and Meta's Velox engine, new "view"
data types were added to the Arrow columnar format spec.
+
+* 16-byte StringView and BinaryView data type which enables better buffer
reuse, faster "false" string comparisons (due to maintaining a prefix) and
short string inlining.
([GH-35627](https://github.com/apache/arrow/issues/35627)).
+* ListView and LargeListView types for more performant "out-of-order" building
and processing of lists and better buffer reuse
([GH-37876](https://github.com/apache/arrow/issues/37876)).
+
+## Arrow Flight RPC notes
+
+A new RPC method was added to allow polling for completion in long-running
queries as an alternative to the blocking GetFlightInfo call
([GH-36155](https://github.com/apache/arrow/issues/36155)). Also,
`app_metadata` was added to `FlightInfo` and `FlightEndpoint`
([GH-37635](https://github.com/apache/arrow/issues/37635)).
+
+In C++ and Python, an experimental asynchronous GetFlightInfo call was added
to the client-side API
([GH-36512](https://github.com/apache/arrow/issues/36512)). `ServerCallContext`
now exposes conveniences to send headers/trailers without having to use
middleware ([GH-36952](https://github.com/apache/arrow/issues/36952)). The
implementation was fixed to not reject unknown field tags to enable
interoperability with future versions of Flight that could add new fields
([GH-36975](https://github.com/apache/arrow/issues/36975)). The CMake
configuration was fixed to correctly require linking to Arrow Flight RPC when
using Arrow Flight SQL
([GH-37406](https://github.com/apache/arrow/issues/37406)).
+
+In Go, the underlying generated Protobuf code is now exposed for easier
low-level integrations with Flight
([GH-36893](https://github.com/apache/arrow/issues/36893)).
+
+In Java, the stateful "login" authentication APIs using the Handshake RPC are
deprecated; it will not be removed, but it should not be used unless you
specifically want the old behavior
([GH-37722](https://github.com/apache/arrow/issues/37722)). Utilities were
added to help implement basic Flight SQL services for unit testing
([GH-37795](https://github.com/apache/arrow/issues/37795)).

+## C++ notes
Review Comment:
```suggestion
## C++ notes
Experimental APIs for exporting and importing non-CPU arrays using the C
Device Data Interface
have been added (GH-36488), together with an experimental API for device
synchronization
(GH-36103).
Initial compatibility with Emscripten without threading support has been
added (GH-35176).
### Compute layer
New compute functions:
* a `cumulative_mean` function on numeric data (GH-36931);
Improved compute functions:
* rounding functions now work natively on integer inputs instead of casting
them to floats (GH-35273);
* the `divide` function now supports duration inputs (GH-36789);
* `take` and `filter` now support sparse unions in addition to dense unions
(GH-36905);
* `if_else`, `coalesce`, `choose` and `case_when` now support duration
inputs (GH-37028);
* casting between fixed-size lists and variable-size lists is now supported
(GH-20086);
* casting from strings to dates is now supported (GH-37411);
* `mean` on integer inputs now uses a floating-point representation for its
intermediate sum,
avoiding integer overflow on large inputs (GH-34909);
### Datasets
Support for writing encrypted Parquet datasets has been added (GH-29238).
### Gandiva
Gandiva now supports linking dynamically to LLVM on non-Windows platforms
(GH-37410).
Previously, Gandiva would always link LLVM statically into `libgandiva`.
### Parquet
RLE is used by default when encoding boolean values if v2 data pages are
enabled
(GH-36882).
Page indexes can now be encrypted as per the specification (GH-34950).
A bug in the DELTA_BINARY_PACKED encoder leading to suboptimal column sizes
was fixed (GH-37939).
### Substrait
It is now possible to serialize and deserialize individual expressions using
Substrait,
not only full query plans (GH-33985).
### Miscellaneous
A new `CodecOptions` class allows customizing compression parameters
per-codec (GH-35287).
The environment variable `AWS_ENDPOINT_URL` is now respected when resolving
S3 URIs (GH-36770).
Recursively listing S3 filesystem trees should now issue less requests,
leading to improved performance (GH-34213).
Comparing a `ChunkedArray` to itself now behaves correctly with NaN values
(GH-37515).
The use of BMI2 instructions on x86 was incorrectly guarded. Those
instructions
could be executed on platforms without BMI2 support, leading to crashes
(GH-37017).
