Good morning, it's October 19th, 2026, and this is your Tailwind C-S-S briefing.
The lead story is correctness: three separate fixes address small logic errors that cause wrong output or crashes, with one already merged to stop silent CSS loss.
First, the highest impact change, merged as pull request 20593. The candidate canonicalizer with collapse enabled could drop a utility that sets a T-W variable, losing styles. When it computed a signature, it ignored a T-W variable if any other property shared the same value. That meant a custom link utility with a…
Second, two open proposals tighten parsing edge cases. Pull request 20591 fixes the unescape helper so a backslash plus a single hex digit is treated as a hex escape, not a plain character. That corrects values like backslash-A and backslash-zero and fixes theme variable normalization. Pull request 20590 fixes…
