RIP XSLT
If you visit feed.xml in your browser, you will see that I have done the Cool Kid thing and added styling to it via XSLT. This was originally something I've wanted to do for years — both for my own blog and for Buttondown — and I finally got around to it, only to immediately learn that XSLT support is being deprecated.
I can't even be particularly upset about the decision. It makes sense and is entirely rational — the security story around libxslt is grim, and if only 0.02% of page loads use XSLT, the cost of maintaining it outweighs the benefit. And yet. It is nonetheless a bummer.
So enjoy those beautiful RSS feeds until November 17, 2026, when they go away forever. Or perhaps I will go with the polyfill option suggested by Chrome to hold on to them for a little bit longer — until that too is inevitably deprecated.
