+We recently released the 5.0.0 Rust version of [Apache
Arrow](https://arrow.apache.org/), and this post highlights some of the
improvements we have made. 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
+This release contains bug fixes, performance improvements, and a slimmer
dependency stack when if default features are disabled. Documentation has been
improved and more examples have been added.
+
+Feature wise, there is a [new
kernel](https://github.com/apache/arrow-rs/pull/424) which lexicographically
partition points as well as usability enhancements for creating and
manipulating Record Batches. Arrow Flight's API usability has [been
improved](https://github.com/apache/arrow-rs/pull/377)
+
+We continue to leverage the Rust ecosystem to deliver reliable and performant
code, and the Rust test suite now includes runs with the [MIRI
checker](https://github.com/rust-lang/miri) (a sort of valgrind for Rust) for
memory access violations.
+
+# 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 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 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/2.0.0/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.
