API Changes

This section documents version-specific API changes — prioritize recent major/minor releases.

• BREAKING: VRow / VCol Grid — complete overhaul using CSS gap instead of negative margins. dense prop removed (use density="compact"), align/justify on VRow and order/align-self on VCol removed in favor of utility classes source

• BREAKING: MD3 Typography — variant names renamed for Material Design 3 compliance: h1-h3 -> display-*, h4-h6 -> headline-*, subtitle-1/body-1 -> body-large, button/subtitle-2 -> label-large source

• BREAKING: MD3 Elevation — elevation levels reduced from 25 (0-24) to 6 (0-5) to align with MD3 density-independent pixel levels source

• BREAKING: VBtn Defaults — text-transform: uppercase removed by default. $button-stacked-icon-margin Sass variable replaced by $button-stacked-gap source

• BREAKING: VSelect / VAutocomplete / VCombobox — item slot prop renamed to internalItem. The item prop is now an alias for internalItem.raw source

• BREAKING: VForm Slot — isValid, errors, and isDisabled slot variables are now unwrapped values instead of Ref objects source

• NEW: VSnackbarQueue — rewritten in v4 to support showing multiple snackbars simultaneously; default slot renamed to item source

• NEW: VRow gap prop — provides fine-grained control over grid spacing, accepting numbers, strings, or [x, y] arrays source

• NEW: VAvatarGroup (experimental) — new labs component for grouping multiple avatars with overlapping support source

• NEW: VCommandPalette (experimental) — new labs component providing a search and action interface for application commands source

Also changed: VCalendar promoted from labs · VHotkey promoted from labs · VToolbar location prop new · VAvatar badge prop new · VProgressCircular reveal prop new · VTreeview indent-lines props new · vuetify/styles/core new entry point · system default theme · VSnackbar multi-line removed · VContainer fill-height behavior changed

Best Practices

• Use the cmd modifier in the useHotkey composable for cross-platform compatibility — automatically resolves to Command on Mac and Control on PC source

// Preferred: works on both Mac and PC
useHotkey('cmd+s', (e) => saveDocument(e))

// Avoid: hardcoding 'ctrl' may cause conflicts or feel non-idiomatic on Mac
useHotkey('ctrl+s', (e) => saveDocument(e))

• Apply class and style to specific component keys in the defaults configuration — these are not supported in the global defaults key source

// Preferred
createVuetify({
  defaults: {
    VBtn: {
      class: 'text-none',
      style: { textTransform: 'none' }
    }
  }
})

// Avoid: class and style are ignored in global
createVuetify({
  defaults: {
    global: { class: 'text-none' }
  }
})

• Resolve style conflicts between Vuetify and TailwindCSS by redefining CSS layer order — place Vuetify's styles in a dedicated layer with lower precedence than Tailwind's base layer source

/* main.css */
@layer theme, base, vuetify, components, utilities;
@import 'vuetify/styles' layer(vuetify);
@import 'tailwindcss';

• Use v-text-field with decimal.js for high-precision decimal arithmetic — VNumberInput uses toFixed() internally and may suffer from standard JavaScript floating-point inaccuracies source

• Centralize snackbar messages using global state (e.g., Pinia) with v-snackbar-queue — allows triggering notifications from any part of the application by pushing to a shared array source

<template>
  <v-app>
    <v-snackbar-queue v-model="messages.queue" />
  </v-app>
</template>

• Use the order prop to explicitly control layout component priority — overrides the default behavior where priority is determined solely by markup order source

<v-navigation-drawer />
<v-app-bar :order="-1" />

• Utilize useDate()'s parseISO and toISO methods for standardizing date strings — VDateInput and other date components internally expect and return native JS Date objects source

• Use v-command-palette (experimental) for keyboard-driven power-user workflows — provides a pre-configured, accessible, and searchable dialog interface that implements ARIA best practices automatically source

• Restore previous negative-margin/padding grid behavior during Vuetify 4 migration using the @layer vuetify-overrides block — necessary when existing layouts rely on the legacy system instead of the new CSS gap property source

@layer vuetify-overrides {
  .v-row {
    gap: unset;
    margin: calc(var(--v-col-gap-y) * -.5) calc(var(--v-col-gap-x) * -.5);
  }
}
