Tailwind CSS v4 removed renamed utilities upgrade guide renamed utilities shadow outline ring blur
A small set of utilities compile but render differently after the major upgrade.
Agent Quick Fix
Repair against the current Tailwind CSS contract, then keep the change narrow and source-backed.
Product: Tailwind CSS
Current-contract area: Tailwind v4 removed/renamed utility semantics cause snapshot drift
Likely root cause: A small set of utilities compile but render differently after the major upgrade.
Repair direction: Verifier checks the current package identity/config format and a real transformed output. Verify a minimal current configuration and actual generated CSS.Symptom
A small set of utilities compile but render differently after the major upgrade.
Why This Happens
The old package/config name is syntactically valid, but current tool packaging and discovery rules live in external release documentation.
Common Wrong Fixes
- Changing local code without checking the current external contract.
- Retrying the same install, build, or API call with no version/source change.
- Applying a broad unsafe bypass when a narrow compatibility fix is available.
