Drupal Commerce achieved its first full release at DrupalCon London 2011. I remember working on it beside Damien Tournoud, Commerce Guys' CTO at the time - one of those rare true geniuses in his element helping me finalize a variety of last minute issues before we tagged and released. More than a few open source eCommerce projects have come and gone since then, but we haven't slowed down yet!
This past week, we packaged Commerce 1.16. It's been over two years since the last release as we've focused primarily on the Drupal 8/9 branch, Commerce 2.x. However, we still found time to make significant performance improvements and incorporate longstanding feature requests like including the order e-mail address when the order is rendered, supporting the deletion of old order and line item revisions impacting the performance of sites with a tremendous amount of orders, and more. For the full list of updates, please refer to the release notes.
