That's not how (modern) SW works. Ever heard of "new features and security improvements" ?
What? This is certainly how not updating Chrome works.
They even took "security" out.
On Android: "Thanks for choosing Chrome! This release includes stability and performance improvements."
Won't a modern version of Chromium build for XP, with some tweaking?
From my experience, there is a lot of software that will not build for platform older than 7/2008 due to missing APIs. Visual studio stopped support for xp compilation awhile ago. You still can use clang or such for simple programs today, but chromium is probably too complicated to port at this point.
I thought I saw it in Visual Studio 2019 but I'm misremembering - Visual Studio 2017 was the last to support building for Windows XP by the looks of it.
Chromium already builds with clang + libc++ on every platform, including Windows.
