Het compressieformaat 7z wordt steeds meer gebruikt voor het comprimeren van bestanden. Het programma p7zip is speciaal geschreven voor verschillende Unix-, BSD- en Linux-platformen en biedt volledige ondersteuning voor het 7z-formaat. De ontwikkelaar heeft een nieuwe versie uitgebracht met 4.42 als het versienummer, deze loopt gelijk met het programma 7-Zip op het Windows-platform. De lijst met aanpassingen ziet er als volgt uit:
Version 4.42:Version 4.39:
