I'm not sure where you have obtained this info, but it has not been officially said that the update will release today. Unless it comes directly from Pipeworks Studio, or a Re-Logic Developer, anything you may've heard about the update releasing today is false. There will be another announcement when the update is ready on the Forums.
In the future, you can use the edit button on the bottom left of your post to edit content into your posts if no one else has posted yet. We ask that you do this rather than double posting in the future.
For your question about the titles, the information can be found here on how to obtain titles:
