The last time I released a version of PCU, I posted on PHP Dev Network asking for suggestions, reviews, rants, insults, etc. There were a few good suggestions on there. Go back and read through them and make sure you implement whatever is still relevant.
After you do that, and after you release v0.0.1 of CSVelte, do the same thing you did with PCU v0.3. Also maybe consider dropping versioning down to just major/minor rather than major/minor/patch. It may be overkill... think on it.
