is it possible that NetNewsWire (possibly other rss readers as well) don't show the favicon for https://news.ycombinator.com/rss anymore because of this change? I noticed this a few days ago
HN is still serving the orange Y for favicons. Only the Y to the left of "Hacker News" in the top bar now has a transparent background.
However, there was a brief period where we were serving the transparent Y for favicons before I noticed that and corrected it; I wonder if the transparent Y somehow got into a cache? Is there a way to force-refresh?
Unfortunately the issue still persists and it doesn't seem to be related to caching.
I think the problem might be that NetNewsWire doesn't support SVG favicons (/y18.svg) and that /favicon.ico isn't available as a fallback. Were there any changes regarding these files recently?
