This evening I saw on ACESCentral.com that the download for OpenColorIO-Config-ACES 1.0.0 is available now. I updated the article Blender 3.4 alpha & OCIO v2 accordingly and I will start soon to do some tests in Blender and Nuke.
The ACES 1.2 release candidate is the last version that will be available for the OCIOv1 framework. Newer OCIO configs that support the OCIOv2 framework are at a pre-release state at the moment. I will try to stop using the OCIOv1 configs and switch over the OCIOv2 configs.
