It would be uncharacteristic of me to miss that type of statement. Of course it’s still possible. I just went through all 216 posts of the pre-release letter and every post of Dan’s since Nov 22. Couldn’t find anything discussing those Pro issues. Is it this topic?
Edit: Or maybe you are just saying that the Pro and Filter aren’t ready for pre-release. If that is so the wording of your question misled me.
Edit2: I give up. Can’t find any such reference.
