A big thanks to the 10 contributors who made this release possible. Here are some highlights ✨:

• 🔧 Moved components to slots prop starting at MUI Base to create consistency across products
• Many other 🐛 bug fixes, 📚 documentation, and ⚙️ infrastructure improvements

@mui/material@5.10.11

• [InputBase] Fix onInvalid to use HTMLInputElement | HTMLTextAreaElement Element type (#33162) @KuSh
• [Alert] Add components and componentsProps props to allow close action overrides (#33582) @jake-collibra

@mui/base@5.0.0-alpha.103

BREAKING CHANGE

• [base] components -> slots API rename (#34693) @michaldudak

  • Change all occurrences of components and componentsProps props in Base components to slots and slotProps, respectively.
  • Change casing of slots' fields to camelCase

  -<SwitchUnstyled components={{Root: CustomRoot}} componentsProps={{rail: { className: 'custom-rail' }}} />
  +<SwitchUnstyled slots={{root: CustomRoot}} slotProps={{rail: { className: 'custom-rail' }}} />
  

• [base] Make CSS class prefixes consistent (#33411) @michaldudak

  This is a breaking change for anyone who depends on the class names applied to Base components. If you use the <component>UnstyledClasses objects, you won't notice a difference. Only if you depend on the resulting class names (e.g. in CSS stylesheets), you'll have to adjust your code.

  -.ButtonUnstyled-root { ... };
  +.MuiButton-root { ... };
