+
+The Apache Arrow team is pleased to announce the 0.5.0 release. It includes
+[**130 resolved JIRAs**][1] with some new features, expanded integration
+testing between implementations, and bug fixes. The Arrow memory format remains
+stable since the 0.3.x and 0.4.x releases.
+
+See the [Install Page][2] to learn how to get the libraries for your
+platform. The [complete changelog][5] is also available.
+
+## Expanded Integration Testing
+
+In this release, we added compatibility tests for dictionary-encoded data
+between Java and C++. This enables the distinct values (the *dictionary*) in a
+vector to be transmitted as part of an Arrow schema while the record batches
+contain integers which correspond to the dictionary.
+
+So we might have:
+
+```
+data (string): ['foo', 'bar', 'foo', 'bar']
+```
+
+In dictionary-encoded form, this could be represented as:
+
+```
+indices (int8): [0, 1, 0, 1]
+dictionary (string): ['foo', 'bar']
+```
+
+In upcoming releases, we plan to complete integration testing for the remaining
+data types (including some more complicated types like unions and decimals) on
+the road to a 1.0.0 release in the future.
+
+## C++ Activity
+
+We completed a number of significant pieces of work in the C++ part of Apache
+Arrow.
+
+### Using jemalloc as default memory allocator
+
+We decided to use [jemalloc][4] as the default memory allocator unless it is
+explicitly disabled. This memory allocator has significant performance
+advantages in Arrow workloads over the default `malloc` implementation. We will
+publish a blog post going into more detail about this and why you might care.
+
+### Sharing more C++ code with Apache Parquet
+
+We imported the compression library interfaces and dictionary encoding
+algorithms from the [Apache Parquet C++ library][3]. The Parquet library now
+depends on this code in Arrow, and we will be able to use it more easily for
+data compression in Arrow use cases.
+
+As part of incorporating Parquet's dictionary encoding utilities, we have
+developed an `arrow::DictionaryBuilder` class to enable building
+dictionary-encoded arrays iteratively. This can help save memory and yield
+better performance when interacting with databases, Parquet files, or other
+sources which may have columns having many duplicates.
+
+### Support for LZ4 and ZSTD compressors
+
+We added LZ4 and ZSTD compression library support. In ARROW-300 and other
+planned work, we intend to add some compression features for data sent via RPC.
+
+## Python Activity
+
+We fixed many bugs which were affecting Parquet and Feather users and fixed
+several other rough edges with normal Arrow use. We also added some additional
+Arrow type conversions: structs, lists embedded in pandas objects, and Arrow
+time types (which deserialize to the `datetime.time` type).
+
+In upcoming releases we plan to continue to improve [Dask][7] support and
+performance for distributed processing of Apache Parquet files with pyarrow.
+
+## The Road Ahead
+
+We have much work ahead of us to build out Arrow integrations in other data
+systems to improve their processing performance and interoperability with other
+systems.
+
+We are discussing the roadmap to a future 1.0.0 release on the [developer
+mailing list][6]. Please join the discussion there.
