## 15.1.0 / 2020-10-05
- Updated to `prism-themes` 1.4.1

## 15.0.1 / 2020-10-03
- Regenerate Prism themes containing nested tokens

## 15.0.0 / 2020-10-03
- Breaking change: Allow styling nested tokens with classes in styles (probably not practically breaking for most, since this is a change that fixes a previously non-working feature)

## 14.0.2 / 2020-10-03

- New default prop value: `showInlineLineNumbers = true`: when `showLineNumbers` is `true`, we now default to inline line numbers instead of putting them in a separate `<code>` block
- Explicit white-space styling on `<code>` tag (will be set to either `white-space: pre` or `white-space: pre-wrap` depending on value of `wrapLongLines` prop)

## 13.5.3 / 2020-09-03
- don't forget to add current version to CHANGELOG at release time :)

## 13.5.2 / 2020-09-03
- filled in CHANGELOG for v10.x through v13.5.1

## 13.5.1 / 2020-08-19
- Brought back `createElement` that went missing as of version 13.5.

```js
import createElement from "react-syntax-highlighter/create-element";
```

## 13.5.0 / 2020-08-17
- Cleaned up old files in project root, add jest to eslint
- Updated to `refractor` 3.1.0, which brings in `prismjs` 1.21.0. We'd pinned `react-syntax-highlighter 13.3.1` to `prismjs 1.21.0`, but didn't realize that `refractor`'s dependency would keep us at 1.20.0

- `dracula`
- `materialDark`
- `materialLight`

## 13.1.0 / 2020-07-23

- demos now autoload full lists of languages and styles from highlight/prism
- minor UI adjustments

## 13.0.0 / 2020-07-23
- latest `highlight ^10.1.1` and `lowlight ^1.14.0` dependencies
- latest `refractor ^3.0.0` and `prism ^1.20.0` dependencies
- updated codecov and lodash deps
- corrected .gitignore

### New prop: `showInlineLineNumbers`

```jsx
<SyntaxHighlighter
  showLineNumbers={true} // required to show line numbers, whether inline or not
  showInlineLineNumbers={true} // render them inside wrapped lines, instead of as a separate <code> block
  renderer={virtualizedRenderer({
    rowHeight: 20
  })}
>
  {code}
</SyntaxHighlighter>
```

When paired with `showLineNumbers={true}`, `showInlineLineNumbers={true}` injects line numbers into each wrapped line of code, instead of creating a separate `<code></code>` block for the numbers. This allows line numbering to work with virtualized renderers such as `react-syntax-highlighter-virtualized-renderer`.

Inline line numbers are styled so that they're not selected when drag-selecting multiple lines of highlighted text, preserving expected behavior.

### Breaking changes
Highlight v10 introduced some breaking changes for us here which we've worked around (mainly that `getLanguage` was no longer exposed), but this shouldn't cause breakage for most people relying on `react-syntax-highlighter` and not consuming `highlight.js` directly.

#### Theme rename

- If you rely on the `darkula` theme from `highlight.js`, highlight v10 has renamed that style to `darcula`.

#### Renamed/removed highlight.js languages
- `cs` (renamed to `csharp`)
- `nimrod` (renamed to `nim`)
- `tex` (removed)

### New languages

> Note: `react-syntax-highlighter` provides an automated build wrapper around styles and languages provided by `highlight.js` (via `lowlight`) and `prism` (via `refractor`). Changes here are simply describing what's changed in those libraries. If you'd like to see another language or style added, please contribute to those libraries.
