+
+The Apache Arrow team is pleased to announce the 0.14.0 release. This
+covers 3 months of development work and includes [**602 resolved
+issues**][1] from [**75 distinct contributors**][2]. See the Install
+Page to learn how to get the libraries for your platform. The
+[complete changelog][3] is also available.
+
+This post will give some brief highlights in the project since the
+0.13.0 release from April.
+
+## New committers
+
+Since the 0.13.0 release, the following have been added:
+
+* [Neville Dipale][5] was added as a committer
+* [François Saint-Jacques][6] was added as a committer
+* [Praveen Kumar][7] was added as a committer
+
+Thank you for all your contributions!
+
+## Upcoming 1.0.0 Format Stability Release
+
+We are planning for our next major release to move from 0.14.0 to
+1.0.0. The major version number will indicate stability of the Arrow
+columnar format and binary protocol. While the format has already been
+stable since December 2017, we believe it is a good idea to make this
+stability official and to indicate that it is safe to persist
+serialized Arrow data in applications. This means that applications
+will be able to safely upgrade to new Arrow versions without having to
+worry about backwards incompatibilities. We will write in a future
+blog post about the stability guarantees we intend to provide to help
+application developers plan accordingly.
+
+## Packaging
+
+We added support for the following platforms:
+
+* Debian GNU/Linux buster
+* Ubuntu 19.04
+
+We dropped support for Ubuntu 14.04.
+
+## Development Infrastructure and Tooling
+
+As the project has grown larger and more diverse, we are increasingly
+outgrowing what we can test in public continuous integration services
+like Travis CI and Appveyor. In addition, we share these resources
+with the entire Apache Software Foundation, and given the high volume
+of pull requests into Apache Arrow, maintainers are frequently waiting
+many hours for the green light to merge patches.
+
+The complexity of our testing is driven by the number of different
+components and programming languages as well as increasingly long
+compilation and test execution times as individual libraries grow
+larger. The 50 minute time limit of public CI services is simply too
+limited to comprehensively test the project. Additionally, the CI host
+machines are constrained in their features and memory limits,
+preventing us from testing features that are only relevant on large
+amounts of data (10GB or more) or functionality that requires a
+CUDA-enabled GPU.
+
+Organizations that contribute to Apache Arrow are working on physical
+build infrastructure and tools to improve build times and build
+scalability. One such new tool is `ursabot`, a GitHub-enabled bot
+that can be used to trigger builds either on physical build or in the
+cloud. It can also be used to trigger benchmark timing comparisons. If
+you are contributing to the project, you may see Ursabot being
+employed to trigger tests in pull requests.
+
+To help assist with migrating away from Travis CI, we are also working
+to make as many of our builds reproducible with Docker and not reliant
+on Travis CI-specific configuration details. This will also help
+contributors reproduce build failures locally without having to wait
+for Travis CI.
+
+## Columnar Format Notes
+
+* User-defined "extension" types have been formalized in the Arrow
+ format, enabling library users to embed custom data types in the
+ Arrow columnar format. Initial support is available in C++, Java,
+ and Python.
+* A new Duration logical type was added to represent absolute lengths
+ of time.
+
+## Arrow Flight notes
+
+Flight now supports many of the features of a complete RPC
+framework.
+
+* Authentication APIs are now supported across all languages (ARROW-5137)
+* Encrypted communication using OpenSSL is supported (ARROW-5643,
+ ARROW-5529)
+* Clients can specify timeouts on remote calls (ARROW-5136)
+* On the protocol level, endpoints are now identified with URIs, to
+ support an open-ended number of potential transports (including TLS
+ and Unix sockets, and perhaps even non-gRPC-based transports in the
+ future) (ARROW-4651)
+* Application-defined metadata can be sent alongside data (ARROW-4626,
+ ARROW-4627).
+
+Windows is now a supported platform for Flight in C++ and Python
+(ARROW-3294), and Python wheels are shipped for all languages
+(ARROW-3150, ARROW-5656). C++, Python, and Java have been brought to
+parity, now that actions can return streaming results in Java
+(ARROW-5254).
+
+## C++ notes
+
+188 resolved issues related to the C++ implementation, so we summarize
+some of the work here.
+
+### General platform improvements
+
+* A FileSystem abstraction (ARROW-767) has been added, which paves the
+ way for a future Arrow Datasets library allowing to access sharded
+ data on arbitrary storage systems, including remote or cloud
+ storage. A first draft of the Datasets API was committed in
+ ARROW-5512. Right now, this comes with no implementation, but we
+ expect to slowly build it up in the coming weeks or months. Early
+ feedback is welcome on this API.
+* The dictionary API has been reworked in ARROW-3144. The dictionary
+ values used to be tied to the DictionaryType instance, which ended
+ up too inflexible. Since dictionary-encoding is more often an
+ optimization than a semantic property of the data, we decided to
+ move the dictionary values to the ArrayData structure, making it
+ natural for dictionary-encoded arrays to share the same DataType
+ instance, regardless of the encoding details.
+* The FixedSizeList and Map types have been implemented, including in
+ integration tests. The Map type is akin to a List of Struct(key,
+ value) entries, but making it explicit that the underlying data has
+ key-value mapping semantics. Also, map entries are always non-null.
+* A `Result<T>` class has been introduced in ARROW-4800. The aim is to
+ allow to return an error as w ell as a function's logical result
+ without resorting to pointer-out arguments.
+* The Parquet C++ library has been refactored to use common Arrow IO
+ classes for improved C++ platform interoperability.
+
+### Line-delimited JSON reader
+
+A multithreaded line-delimited JSON reader (powered internally by
+RapidJSON) is now available for use (also in Python and R via
+bindings) . This will likely be expanded to support more kinds of JSON
+storage in the future.
+
+### New computational kernels
+
+A number of new computational kernels have been developed
+
+* Compare filter for logical comparisons yielding boolean arrays
+* Filter kernel for selecting elements of an input array according to
+ a boolean selection array.
+* Take kernel, which selects elements by integer index, has been
+ expanded to support nested types
+
+## C# Notes
+
+The native C# implementation has continued to mature since 0.13. This
+release includes a number of performance, memory use, and usability
+improvements.
+
+## Go notes
+
+Go's support for the Arrow columnar format continues to expand. Go now
+supports reading and writing the Arrow columnar binary protocol, and
+it has also been **added to the cross language integration
+tests**. There are now four languages (C++, Go, Java, and JavaScript)
+included in our integration tests to verify cross-language
+interoperability.
+
+## Java notes
+
+* Support for referencing arbitrary memory using `ArrowBuf` has been
+ implemented, paving the way for memory map support in Java
+* A number of performance improvements around vector value access were
+ added (see ARROW-5264, ARROW-5290).
+* The Map type has been implemented in Java and integration tested
+ with C++
+* Several microbenchmarks have been added and improved. Including a
+ significant speed-up of zeroing out buffers.
+* A new algorithms package has been started to contain reference
+ implementations of common algorithms. The initial contribution is
+ for Array/Vector sorting.
+
+## JavaScript Notes
+
+A new incremental [array builder API][4] is available.
+
+## MATLAB Notes
+
+Version 0.14.0 features improved Feather file support in the MEX bindings.
+
+## Python notes
+
+* We fixed a problem with the Python wheels causing the Python wheels
+ to be much larger in 0.13.0 than they were in 0.12.0. Since the
+ introduction of LLVM into our build toolchain, the wheels are going
+ to still be significantly bigger. We are interested in approaches to
+ enable pyarrow to be installed in pieces with pip or conda rather
+ than monolithically.
+* It is now possible to define ExtensionTypes with a Python
+ implementation (ARROW-840). Those ExtensionTypes can survive a
+ roundtrip through C++ and serialization.
+* The Flight improvements highlighted above (see C++ notes) are all
+ available from Python. Furthermore, Flight is now bundled in our
+ binary wheels and conda packages for Linux, Windows and macOS
+ (ARROW-3150, ARROW-5656).
+* We will build "manylinux2010" binary wheels for Linux systems, in
+ addition to "manylinux1" wheels (ARROW-2461). Manylinux2010 is a
+ newer standard for more recent systems, with less limiting toolchain
+ constraints. Installing manylinux2010 wheels requires an up-to-date
+ version of pip.
+* Various bug fixes for CSV reading in Python and C++ including the
+ ability to parse Decimal(x, y) columns.
+
+### Parquet improvements
+
+* Column statistics for logical types like unicode strings, unsigned
+ integers, and timestamps are casted to compatible Python types (see
+ ARROW-4139)
+* It's now possible to configure "data page" sizes when writing a file
+ from Python
+
+## Ruby and C GLib notes
+
+The GLib and Ruby bindings have been tracking features in the C++
+project. This release includes bindings for Gandiva, JSON reader, and
+other C++ features.
+
+## Rust notes
+
+There is ongoing work in Rust happening on Parquet file support,
+computational kernels, and the DataFusion query engine. See the full
+changelog for details.
+
+## R notes
+
+We have been working on build and packaging for R so that community
+members can hopefully release the project to CRAN in the near
+future. Feature development for R has continued to follow the upstream
+C++ project.
+
+## Community Discussions Ongoing
+
+There are a number of active discussions ongoing on the developer
+dev@arrow.apache.org mailing list. We look forward to hearing from the
+community there:
+
+* [Timing and scope of 1.0.0 release][15]
+* [Solutions to increase continuous integration capacity][13]
+* [A proposal for versioning and forward/backward compatibility
+ guarantees for the 1.0.0 release][8] was shared, not much discussion has
+ occurred yet.
+* [Addressing possible unaligned access and undefined behavior concerns][9]
+ in the Arrow binary protocol
+* [Supporting smaller than 128-bit encoding of fixed width decimals][10]
+* [Forking the Avro C++ implementation][11] so as to adapt it to Arrow's
+ needs
+* [Sparse representation and compression in Arrow][12]
+* [Flight extensions: middleware API and generalized Put operations][14]
