By The Apache Arrow PMC (pmc)

The Apache Arrow team is pleased to announce the 19.0.1 release.

This release primarily addresses a bug in the recent Arrow 19.0.0 release which prevents Arrow C++ and libraries binding it (e.g., Python, R) from reading Parquet files created by Arrow Rust v53.0.0 or more recent. See the 19.0.0 release blog post for more information.

This release includes 12 resolved issues from 9 distinct contributors. See the Install Page to learn how to get the libraries for your platform.

The release notes below are not exhaustive and only expose selected highlights of the release. Other bugfixes and improvements have been made: we refer you to the complete changelog.
