4 PDF Utilities: jPDF Tweak, PDF Scissors, PDF Droplet, and PDFsam

I'm not completely clear on current procedures, as I've seen documentation referencing the "Test Releases" page and the "Apps Ready for Official Release" page, but the former page appears to show releases that have been stuck in queue for over 5 years and the later page even longer. Even some apps posted in this forum seem to have gone 5+ years without response. Portable apps are clearly still being published though, so I'm hoping someone might be so kind as to point me in the right direction if this is not the right place.
