Breaking change

• [Typography] Remove deprecated Typography variants (#14562) @joshwooding

  • Remove the deprecated typography variants. You can upgrade by performing the following replacements:
    • display4 => h1
    • display3 => h2
    • display2 => h3
    • display1 => h4
    • headline => h5
    • title => h6
    • subheading => subtitle1
    • body2 => body1
    • body1 (default) => body2 (default)
  • Remove the opinionated display: block default typograpghy style.
    You can use the new display?: 'initial' | 'inline' | 'block'; property.
  • Rename the headlineMapping property to better align with its purpose.

  -<MuiTypography headlineMapping={headlineMapping}>
  +<MuiTypography variantMapping={variantMapping}>

• [InputLabel] Remove FormLabelClasses in favor of asterisk class (#14504) @umairfarooq44

You should be able to override all the styles of the FormLabel component using the css API of the InputLabel component. We do no longer need the FormLabelClasses property.

<InputLabel
- FormLabelClasses={{ asterisk: 'bar' }}
+ classes={{ asterisk: 'bar' }}
>
  Foo
</InputLabel>

• [TablePagination] Only raise a warning when the page is out of range (#14534) @leMaik

The TablePagination component does no longer try to fix invalid (page, count, rowsPerPage) property combinations. It raises a warning instead.

Breaking changes

• [styles] Change the withTheme API (#14565) @oliviertassinari

Remove the first option argument of withTheme(). The first argument was a placeholder for a potential future option. We have never found a need for it. It's time to remove this argument. It matches the emotion and styled-components API.

-const DeepChild = withTheme()(DeepChildRaw);
+const DeepChild = withTheme(DeepChildRaw);
