Similar to how you have made a Mozilla Firefox (Minefield) PortableApp release available (even though it is Alpha software), I would like to see 7-Zip 9.14 Beta made available in a PortableApp version.
7-Zip 9.x has seen nine (9) beta releases over the last 13 months. And even though it is technically beta/unstable, I haven't found it to be that unstable.
I'm certainly not suggesting doing away with the 7-Zip 4.65 Rev 2 PortableApp version, but maybe you could release a 7-Zip 9.x Beta PortableApp version and have a blurb about it (similar to how you've handled the Mozilla Firefox/Minefield PortableApp) on the 4.65 Rev 2 page letting those that want to test the 7-Zip 9.x Beta PortableApp know that it is available.
Thanks in advance for considering...
