What's the best way to access newer features in Safari if one's work computer is locked to the previous version of macOS?

Not a lawyer etc. but in my experience? Remove the corporate build and install what you want. Carry an Ethernet adapter.

Most workplaces, upon seeing that you’ve done this, will say “look, you can reinstall the corporate profile, or you can hand back the computer, or you can be fired.” (And if they catch you doing any circumvention to prevent them from finding out, then your options are likely to be “you can be fired”)

> WebKit added support for lazy-loading images with the loading attribute on the element, providing web developers with an easy way to instruct the browser to defer loading certain images until the user scrolls near them Maybe there's hope that I can then just turn this off on a browser level? I've got gigabit internet at home, and your images popping in on scroll makes it feel like I'm on dial up. Lazy loading image…

> Lazy loading images is at best user hostile bandwidth saving

It can easily be the vast majority of bandwidth spend even on a lightweight site. Add video widgets and bring that closer to 99%. Lazy loading is frequently a "can afford an extra 5 full time engineers" optimization

Earlier quoted context omitted.

Personally I really hope they don't add this. Imagine how annoying to have to decline a "please turn on notifications" on every news site on your phone (which you're spammed with on desktop).

That would annoy me, too. Maybe they could have it only work for when you Add to Homescreen as a progressive web app, then it would be more opt-in.

This is actually the perfect compromise that I haven’t even thought of until you’ve mentioned it. Up until now, I was opposed to webkit push notifications for the same reason as the grandparent comment. Thank you for your comment.

Chrome has the same feature and lets you disable it. That's probably the best compromise. You have amazing Internet. For the typical user, heavy image loading slows them down, and they're also less comfortable diving into browser settings.

If it's implemented properly, and your internet is actually that fast, you won't actually see them loading.

If you don’t have gigabit internet (i.e. most people), then it’s not so user hostile.

I find this figure suspect. I work on a site with millions of users whose core service is essentially displaying a stream of images to end users, and our spend on CDN bandwidth is barely into five figures

Safari 15 (including this release) is compatible with Catalina and Big Sur, you don't need to upgrade macOS releases.
