## 4.6.0
###### *Nov 5, 2019*

Big thanks to the 26 contributors who made this release possible.

Here are some highlights ✨:

- 🔍 8 patches on the Autocomplete component that was released last week.

The positive feedback we had this early version of the component is encouraging.
Developers should be able to rely on it in production within a couple of weeks (from a bug perspective).
We will take more time to stabilize the API, a couple of months.

- 📚 Split the TextField demos into smaller demos (#17483) @joshwooding
- 💄 Add a color prop to the TextField (#17891) @ValentinH
- 💄 Add square and rounded variant to the Avatar (#18116) @mattdotam
- 🐛 Fix Chip <> Avatar rendering issue (#18156)

By chance, it's the third year in a row we release on november 5th.
The number of contributors involved, for a similar one-week period, has grown from 12 contributors (2017) to 16 contributors (2018) to 26 contributors (2019).

## 4.5.1
###### *Oct 12, 2019*

Big thanks to the 28 contributors who made this release possible!

Here are some highlights ✨:

- 📚 Change imports from @material-ui/styles to @material-ui/core/styles (#17447) @mnemanja

  The presence of two almost identical import paths has been a source of confusion: `@material-ui/styles` and `@material-ui/core/styles`.
  Starting with v4.5.1, the documentation mentions `@material-ui/core/styles` as much as possible.

  ```diff
  -import { makeStyles } from '@material-ui/styles';
  +import { makeStyles } from '@material-ui/core/styles';
  ```

  This change removes the need to install the `@material-ui/styles` package directly.
  It prevents the duplication of `@material-ui/styles` in bundles and avoids confusion.
  You can [learn more about the difference](https://material-ui.com/styles/basics/#material-ui-core-styles-vs-material-ui-styles) in the documentation.
- ♿️ Improve the accessibility of the table and select components (#17696, #17773) @adeelibr, @eps1lon.
- 📊 Launch a [developer survey](https://www.surveymonkey.com/r/5XHDL76) as a precursor to a major DatePicker enhancement effort.
- 💄 Add support for different [slider track mode](https://material-ui.com/components/slider/#track) (#17714) @slipmat.
- And many more 🐛 bug fixes and 📚 improvements.

###### *July 28, 2019*

Big thanks to the 23 contributors who made this release possible!

Here are some highlights ✨:

- 🌳 Introduce a new Tree View component in the (#14827) @joshwooding.

  This is a first step toward a feature rich tree view component.
  We will keep iterate on it to add customization demos, filter, drag and drop, and checkboxes.
  You can find the documentation under [this URL](https://material-ui.com/components/tree-view/).
- 💄 Support vertical tabs (#16628) @josephpung.

  You can learn more about it following [this URL](https://material-ui.com/components/tabs/#vertical-tabs).
- 📚 Remove the prop-types from TypeScript demos (#16521) @merceyz.

  The runtime prop-types are often redundant with the static type checks.
  We have removed them from the TypeScript demos.
- ⚛️ Add two codemods to improve the imports (#16192) @jedwards1211.

  If you are not familiar with codemods, [check the library out](https://github.com/facebook/codemod). This is a tool tool to assist you with large-scale codebase refactors.
  We introduce two new codemods in this release:

  - `optimal-imports`: Material-UI supports tree shaking for modules at 1 level depth maximum.
  You shouldn't import any module at a higher level depth.

  ```diff
  -import createMuiTheme from '@material-ui/core/styles/createMuiTheme';
  +import { createMuiTheme } from '@material-ui/core/styles';
  ```
  - `top-level-imports`: Converts all @material-ui/core submodule imports to the root module.

  ```diff
  -import createMuiTheme from '@material-ui/core/styles/createMuiTheme';
  +import { createMuiTheme } from '@material-ui/core';
  ```

- 💄 Support small switch (#16620) @darkowic.

  You can learn more about it following [this URL](https://material-ui.com/components/switches/#sizes).
- And many more 🐛 bug fixes and 📚 improvements.
