+We recently released the 5.0.0 Rust version of [Apache
Arrow](https://arrow.apache.org/) which coincides with the [Arrow 5.0.0
release](https://arrow.apache.org/release/5.0.0.html). This post highlights
some of the improvements in the Rust implementation. The full changelog can be
found [here](https://github.com/apache/arrow-rs/blob/5.0.0/CHANGELOG.md).

+-->
+
+The Rust Arrow implementation would not be possible without the wonderful work
and support of our community, and the 5.0.0 release is no exception. It
includes 161 commits from 34 individual contributors, many of them with their
first contribution. Thank you all very much.
+
+# Arrow
+Feature-wise, this release adds:
+1. A [new kernel](https://github.com/apache/arrow-rs/pull/424) which
lexicographically partitions points.
+2. [Expanded support](https://github.com/apache/arrow-rs/pull/439) for the
FFI/[C data
interface](https://arrow.apache.org/docs/format/CDataInterface.html), easing
integration with the broader Arrow ecosystem
+3. Usability enhancements for creating and manipulating `RecordBatch`es.
+4. [Improved usability](https://github.com/apache/arrow-rs/pull/377) for Arrow
Flight's API.
+5. Slimmer dependency stack when default features are disabled
+
+We continue to leverage the Rust ecosystem to deliver reliable and performant
code. We made significant progress towards running the Rust test suite under
the [MIRI checker](https://github.com/rust-lang/miri) (a sort of valgrind for
Rust) for memory access violations, and we expect it to be fully enabled in CI
for the 5.1.0 release.
+
+Of course, this release also contains bug fixes, performance improvements, and
improved documentation examples. For the full list of changes, please consult
the [changelog](https://github.com/apache/arrow-rs/blob/5.0.0/CHANGELOG.md).
+
+# Parquet
+The `parquet-derive` crate now automatically derives the required parquet
schema, and the `parquet` crate had several bug fixes and enhancements.
+
+# More Frequent Releases
+Arrow releases major versions every three months. The Rust implementation has
been experimenting with releasing minor version updates to speed the flow of
new features and fixes. By implementing a new development process, as described
in [A New Development Workflow for Arrow's Rust
Implementation](https://arrow.apache.org/blog/2021/05/04/rust-dev-workflow/) we
have successfully created 4 minor releases on the 4.x.x line every other week
without any reports of breakage.
+
+You can always find the latest releases on crates.io:
[`arrow`](https://crates.io/crates/arrow),
[`parquet`](https://crates.io/crates/parquet),
[`arrow-flight`](https://crates.io/crates/arrow-flight), and
[`parquet-derive`](https://crates.io/crates/parquet-derive).
+
+# DataFusion & Ballista
+[DataFusion](https://docs.rs/datafusion/4.0.0/datafusion/) is an in-memory
query engine with DataFrame and SQL APIs, built on top of Arrow. Ballista is a
distributed compute platform. These projects are now in their [own
repository](https://github.com/apache/arrow-datafusion), and are no longer
released in lock-step with Arrow. Expect further news in this area soon.
+
+# Roadmap for 6.0.0 and Beyond
+Here are some of the initiatives that contributors are currently working on
for future releases:
+
+* Improved performance of compute kernels
+* Date/time/timestamp/interval compute kernels
+* MapArray support
+* Preparations for removing the use of `unsafe` to make arrow faster and more
secure -- see the [mailing
list](https://lists.apache.org/thread.html/recac1f6dc982bab2923f8fb6992e2d4c927f46daff5f03ed6c4de19c%40%3Cdev.arrow.apache.org%3E)
discussion for more details.

+# How to Get Involved
+If you are interested in contributing to the Rust implementation of Apache
Arrow, we would love to have you! You can help by trying out Arrow on some of
your own data and projects and filing bug reports and helping to improve the
documentation, or contribute to the documentation, tests or code. A list of
open issues suitable for beginners is
[here](https://github.com/apache/arrow-rs/labels/good%20first%20issue) and the
full list is [here](https://github.com/apache/arrow-rs/issues).
