This is due to the inconsistent RSS feed messages being put out by the CE team. I've added in "patch", "hotfix" and "update" as keywords that the RSS title must start with. (added update for the next version).
Yup, I already convert the first word to uppercase and check against that. =) And as to inconsistent, they started off with PATCH, then started using HOTFIX and UPDATE. No problem adding them in, the problem it, its just always after the fact. heh
