Good morning, it's October 25th, 2026 — this is your Tailwind C-S-S briefing.

First, quoted text in arbitrary values will now be left alone. In PR 20615, the issue was that the logic that adds whitespace around math operators ran on the entire decoded value without awareness of quotes. That meant a utility like content with the string quote open parenthesis min one comma two close parenthesis…

Second, a test reliability fix for upgrades. In PR 20616, the half-upgraded version three to version four upgrade test using Bun is pinned to Bun version 1.4.3. The test was picking up Bun 1.4.4, released October 22nd, which copies override settings from the workspace config into package dot JSON during install. The…
