[ANNOUNCE] Apache Parquet Format release 2.9.0

[Antoine Pitrou <an...@python.org>]

Hello,

I'm pleased to announce the release of the Apache Parquet Format version 
2.9.0.

Parquet is a general-purpose columnar file format for nested data. It 
uses space-efficient encodings and a compressed and splittable structure 
for processing frameworks like Hadoop.

Version 2.9.0 makes minor improvements and fixes to the Parquet format 
specification. A significant improvement is the addition of the LZ4_RAW 
compression algorithm which deprecates the unfortunately underspecified 
LZ4 algorithm.

The full list of changes for this release is available below:
https://github.com/apache/parquet-format/blob/apache-parquet-format-2.9.0/CHANGES.md

This release can be downloaded from: https://parquet.apache.org/downloads/

Thanks to everyone for contributing!

Regards,

Antoine Pitrou.
