Subject: [ANNOUNCE] Apache Iceberg C++ ${version} released

Hello everyone,

I'm pleased to announce the release of Apache Iceberg C++ ${version}!

Apache Iceberg is an open table format for huge analytic datasets.
Iceberg delivers high query performance for tables with tens of
petabytes of data, along with atomic commits, concurrent writes, and
SQL-compatible table evolution.

This release can be downloaded from [1].

Release notes are available at [2].

Thanks to everyone for contributing!
