"Portable" htop 2.0 works on FreeBSD[0], OpenBSD[1] and OSX[2], not just "various flavours of linux".

Back in the day it wasn't unusual for something to support 30-odd variations on Unix, plus VMS and Windows. ./configure && make && make install. Those were the days!

It also works on various BSDs and OS X in addition to Linux.

I'm pretty sure it worked on most Linux distros and even on mac. I don't see how it's big news.

That's not progress, it's just faulty marketing.

Mainline htop never worked on OSX. OSX's htop is a fork of 0.8.2 with all the linux stuff stripped out and replaced, and then not really updated (let alone resynced with mainline): https://github.com/AndyA/htop-osx
