Just as a recap, with LTS releases, we plan on providing a release train that only has backported changes. 1.409.2 contains a handful of important bug fixes since 1.409.1. For more about LTS, see this wiki page.
Thanks to the heroic effort of those who are involved, namely Vojtech Juranek and a bunch of heroes, this release went through a rather rigorous testing, including all the automated tests we have plus a considerable number of manual eye-ball tests.
To download, click the "Long-Term Support Release" tab from the top page. If you've already been using LTS, you should start receiving update notifications soon.
