Sourced from tailwindcss's releases.

v4.3.0

Added

  • Add @container-size utility (#18901)

CRITICAL: Major breaking change - Upgrading Tailwind CSS from v3 to v4

This is a significant upgrade. Tailwind v4 is a complete rewrite that no longer uses JavaScript config files (tailwind.config.ts). Your current config with custom colors, animations, and the tailwindcss-animate plugin will NOT work in v4.

You need to either:

  1. Migrate the entire configuration to CSS-based @theme directive
  2. Or use @tailwindcss/vite plugin which has backward compatibility

Without this migration, your app will lose all custom colors, border radius, and animations.

Issues found in unchanged code that cannot receive inline comments:

File Line Issue
tailwind.config.ts 1-81 Existing Tailwind v3 config incompatible with v4 - needs migration to CSS @theme
app/globals.css - May need updates for Tailwind v4 syntax
Files Reviewed (3 files)

  • pnpm-lock.yaml - lock file updates (auto-generated)
  • package-lock.json - lock file updates (auto-generated)

Incremental Review: No new issues introduced. The Tailwind CSS upgrade from v3 to v4 remains the primary concern. Your existing tailwind.config.ts with custom colors, animations, and the tailwindcss-animate plugin will not work with v4. You need to either migrate the configuration to CSS-based @theme directive or use the @tailwindcss/vite plugin for backward compatibility.

Re-reviewed after new commit (250178d). The only change since last review is the dependabot bump itself (package.json + pnpm-lock.yaml). The previously flagged breaking change remains unresolved.

  • tailwindcss v3 -> v4 is a breaking major upgrade: the project's tailwind.config.ts, postcss.config.mjs, globals.css directives, and tailwindcss-animate plugin are all incompatible with v4. Either pin to v3 or perform a full v4 migration before merging.

This bumps tailwindcss from v3 to v4, which is a major version with a completely different architecture. This will break the application because the project is set up entirely for v3:

  • tailwind.config.ts uses v3-style JS configuration (content, darkMode, theme.extend, plugins: [require("tailwindcss-animate")]). Tailwind v4 replaced this with CSS-based configuration and does not read tailwind.config.ts by default.
  • postcss.config.mjs registers tailwindcss directly as a PostCSS plugin. v4 requires @tailwindcss/postcss instead.
  • app/globals.css uses @tailwind base;, @tailwind components;, @tailwind utilities; directives, which are removed in v4 and replaced with @import "tailwindcss".
  • The tailwindcss-animate plugin uses v3's require() plugin API which no longer exists in v4.

All custom theme colors, border radius tokens, keyframes, and dark mode setup will stop working. This PR should not be merged without a full Tailwind v4 migration, or the version constraint should remain pinned to v3.

Fix it with Roo Code or mention @roomote and request a fix.
