Currently https://natron.fr/download/ points to the 2.1.2 version of Natron, but the latest version is 2.3.0 (I've found it here). Please fix it.
What is the best way to report such issues?(This topic should be deleted after link fix, I guess.)
This is the link to the issue reporting site at https://github.com/MrKepzie/Natron/issues.
Natron's download site has been fixed. You can tell your professional post house to give it a try now.
