It is now easier to manage controlled tabs state with string value instead of index
With new component structure it is now easier to modify styles of each part with sx or classname props

Tooltip

Tooltip now requires children to be an element or a component,
string, numbers, fragments and multiple elements are no longer supported. In addition to that Tooltip no longer wraps target
element with div tag, events are added directly to target element.

import { Tooltip, Badge } from '@mantine/core';

function Demo() {
  return (
    <>
      <Tooltip label="OK">
        <button>Native button – ok</button>
      </Tooltip>

      <Tooltip label="OK">
        <Badge>Mantine component – ok</Badge>
      </Tooltip>

      <Tooltip label="Throws">Raw string, NOT OK – will throw error</Tooltip>

      {/* Number, NOT OK – will throw error */}
      <Tooltip label="Throws">{2}</Tooltip>

      <Tooltip label="Throws">
        <>Fragment, NOT OK, will throw error</>
      </Tooltip>

      <Tooltip label="Throws">
        <div>More that one node</div>
        <div>NOT OK, will throw error</div>
      </Tooltip>
    </>
  );
}

Popover

Popover component now has new API with the following breaking changes:

placement prop is no longer supported, Popover side and alignment is now controlled with position prop
Default value for trapFocus and withinPortal props is now false
Close button and title are no longer supported, if you need these parts – add them on your side in Popover.Dropdown component

Popover now supports the following new features:

Uncontrolled and controlled mode
width="target" prop will make popover width the same as target element
Popover.Dropdown can now be styled with system props (sx, className, padding props, etc.)

Menu no longer provides default control, it should now be added with Menu.Target
Menu.Item component should now be used within Menu.Dropdown component
trapFocus prop was removed – now it is managed automatically based on trigger prop
closeOnScroll prop was removed – if you need this feature you will need to implement this logic on your side

Avatar

AvatarsGroup component is no longer exported from @mantine/core package, instead you can now use
Avatar.Group component which can be combined with Tooltip or Popover to display additional information.

InputWrapper

InputWrapper component is no longer exported from @mantine/core package, instead you can now use
Input.Wrapper component.

Dropzone

Dropzone component was migrated to context, it no longer supports
function as children. Instead, you can use Dropzone.Accept, Dropzone.Reject and Dropzone.Idle components
to display content based on current status.

Other Dropzone changes:

FullScreenDropzone component is no loner exported from the @mantine/dropzone package, use Dropzone.FullScreen component instead
Dropzone.FullScreen now supports all props from Dropzone component
Dropzone now uses data-* attributes instead of classes to change styles of root element based on current status
Dropzone and Dropzone.FullScreen components now supports the following new props: maxFiles, autoFocus, activateOnClick, activateOnDrag, activateOnKeyboard, dragEventsBubbling, onDragEnter, onDragLeave, onDragOver, onFileDialogCancel, onFileDialogOpen, preventDropOnDocument

Migration to Floating UI

All components that have dropdowns (DatePicker, Popover, Select, etc.)
were migrated to Floating UI from popper.js:

position and placement props were merged into position prop, for example, position="top-start"
Popper component is no longer exported from @mantine/core package

MantineProvider changes

defaultProps, styles and classNames props

MantineProvider no longer supports styles, classNames and defaultProps props.
Instead of separate props these values should be added to the theme. This change allows to store
all components in one object and share it across multiple environments. For example, it is now much easier
to share theme between application and Storybook:

import { MantineProvider } from '@mantine/core';

function Demo() {
  return (
    <MantineProvider
      theme={{
        components: {
          Tabs: {
            defaultProps: { color: 'red' },
            classNames: { root: 'tabs-root' },
            styles: (theme) => ({
              tab: {
                '&[data-active]': { backgroundColor: theme.colors.red[5] },
              },
            }),
          },
        },
      }}
    >
      <App />
    </MantineProvider>
  );
}

emotionCache prop

MantineProvider no longer supports emotionOptions
prop, instead you will need to create emotion cache on your side and provide it with emotionCache prop.
This change was made to enable custom cache to be used during ssr and support more options for emotion
usage, for example with shadow dom or with iframe.

import { MantineProvider, createEmotionCache } from '@mantine/core';

const myCache = createEmotionCache({ key: 'mantine' });

function Demo() {
  return (
    <MantineProvider emotionCache={myCache} withGlobalStyles withNormalizeCSS>
      <App />
    </MantineProvider>
  );
}

Emotion packages as peer dependencies

@emotion/react and @emotion/server packages are now not installed automatically (see related issue) –
you will need to install them manually:

yarn add @emotion/react @emotion/server

Styles API changes

data- attributes

Most of components state were migrated to data- attributes. This allows to override styles
more predictably without using !important and reduces complexity of components Styles API.

Inputs styles API

You can use Input and Input.Wrapper Styles API
on MantineProvider to add styles to all Inputs.

Polymorphic components changes

Because of internal changes polymorphic components props types exported from @mantine/core package are no longer generic types.
Now if you want to extend these types you need to provide associated element types on your side.
You can find updated polymorphic components guide here.

import type { ButtonProps } from '@mantine/core';

// Previously, no longer supported
type MyButtonProps = ButtonProps<'button'> & { label: string };

// Convert to
type MyButtonProps = ButtonProps & React.ComponentPropsWithoutRef<'button'> & { label: string };

@mantine/form changes

use-form no longer exports formList function, you can now
manage lists with just regular arrays. Other changes:

You can now use objects and lists with any level of nesting
useForm hook now supports clearInputErrorOnChange option to disable error clearing when input value changes and validateInputOnChange option that adds support for live fields validation
form.onSubmit handler now accepts second argument – a function that will be called with errors object when validation fails
form.addListItem was renamed to form.insertListItem, it now supports inserting items add given index

Other breaking changes

Select and MultiSelect component now require returning created item from onCreate handler
Portal component no longer accepts position and zIndex props – it is now required to add these styles to Portal children
Modal component no longer supports size="full", use size="100%" instead
FloatingTooltip component was renamed to Tooltip.Floating
Most components with dropdowns (Tooltip, Popover, ColorPicker, DatePicker, Select, etc.) are no longer using Portal by default, it is now required to set withinPortal if you need this feature
Input no longer supports headless variant, use unstyled prop instead
AppShell fixed prop is now true by default
CheckboxGroup, RadioGroup and Chips components are no longer exported from @mantine/core, use Checkbox.Group, Radio.Group and Chip.Group components instead
@mantine/hooks package no longer exports old use-form hook, use @mantine/form package instead
Group component no longer supports direction prop, use Stack component instead for vertical stacks
use-uncontrolled hook logic was changed, it no longer supports rule parameter
use-id hook now supports React 18 useId hook with a fallback for older React versions, generateId function is no longer supported
@mantine/hooks package no longer exports useBooleanToggle hook, use useDisclosure hook instead
use-toggle hook API was changed, it no longer accepts initial value as first argument
use-intersection hook API was changed to keep API consistent across all hooks
use-focus-return hook no longer supports transitionDuration prop due to changes in use-focus-trap hook
use-notifications hook from @mantine/notifications package no longer has showNotification, hideNotification and other functions, use separate functions exported from the package for that

@mantine/carousel package

New @mantine/carousel package based on embla carousel.

@mantine/nprogress package

New @mantine/nprogress package displays navigation
progress bar at the top of the page, it can be easily integrated with Next.js and other similar
frameworks.

React 18 support

All Mantine components now support React 18, all known issues related to React 18 migration
were fixed:

ColorPicker and ColorInput components no longer throw error on value change
Issue with stale Dropzone status was fixed
Multiple issues with types were fixed (mostly related to children prop changes)
The entire Mantine codebase was migrate to React 18 (documentation website, Mantine UI, all packages)

Unstyled components

All components now support unstyled prop which removes all non-essential Mantine styles
from the component. This is useful when you want to style some component from scratch
without overwriting any styles.

New theme properties

theme.activeStyles lets you override styles added to buttons with :active pseudo-class
theme.headings now has an option to set fontWeight for each heading individually:
theme.defaultGradient defines default gradient value for components that support variant="gradient" (Button, ThemeIcon, etc.).
theme.respectReduceMotion allows to disregard user OS settings and play animations as usual:
theme.cursorType determines which cursor type will native controls have.
If it is set to pointer then Checkbox,
Radio, NativeSelect
and other native elements will have cursor: pointer style.

New components

New features

New ScrollArea.Autosize component lets you use ScrollArea with maxHeight
New Tooltip.Group component can be used to sync open and close delays for multiple tooltips
New Button.Group component merges borders of adjacent buttons
Modal component now supports fullScreen prop
All inputs that use Input.Wrapper component under the hood (TextInput, Autocomplete, DatePicker, etc.) now support inputContainer prop. This prop let you add additional elements before/after input element or add floating elements that will be positioned relative to the input. Example with Tooltip.
New inputWrapperOrder prop allows to define the order of Input.Wrapper parts.
Input component now exposes Input.Label, Input.Error and Input.Description, that were previously the parts of InputWrapper component. You can use these components to create custom form layouts if default Input.Wrapper layout does not fit your requirements.
Card.Section now supports the following props to simplify customizations: withBorder prop will add top and bottom border to Card.Section depending on its position relative to other content and sections; inheritPadding prop will add the same left and right padding to Card.Section as set in Card component
