### Breaking changes

Drop support for deprecated setting ldap_sync_ttl under [auth.proxy]
Only sync_ttl will work from now on Issue [#49902](https://github.com/grafana/grafana/issues/49902)

Removes support for deprecated `heading` and `description` props. Moving forward, the `Card.Heading` and `Card.Description` components should be used. Issue [#49885](https://github.com/grafana/grafana/issues/49885)

Removes the deprecated `link` variant from the `Button` component.
To migrate, replace any usage of `variant="link"` with `fill="text"`. Issue [#49843](https://github.com/grafana/grafana/issues/49843)

Removes the deprecated `surface` prop from the `IconButton` component. This prop hasn't actually done anything for a while, so it should be safe to just remove any instances of its usage.
Issue [#49715](https://github.com/grafana/grafana/issues/49715)

Removes the deprecated `TextDisplayOptions` export from `@grafana/data` in favor of `VizTextDisplayOptions` from `@grafana/schema`. To migrate, just replace usage of `TextDisplayOptions` with `VizTextDisplayOptions`. Issue [#49705](https://github.com/grafana/grafana/issues/49705)

Removed support for the deprecated `getColorForTheme(color: string, theme: GrafanaTheme)` function in favor of the
`theme.visualization.getColorByName(color: string)` method. The output of this method is identical to the removed function, so migration should just be a matter of rewriting calls of `getColorForTheme(myColor, myTheme)` to `myTheme.visualization.getColorByName(myColor)`.
Issue [#49519](https://github.com/grafana/grafana/issues/49519)

In the Prometheus data source, for consistency and performance reasons, we changed how we represent `NaN` (not a number) values received from Prometheus. In the past versions, we converted these to `null` in the frontend (for dashboard and explore), and kept as `NaN` in the alerting path. Starting with this version, we will always keep it as `NaN`. This change should be mostly invisible for the users. Issue [#49475](https://github.com/grafana/grafana/issues/49475)

Plugins using custom Webpack configs could potentially break due to the changes between webpack@4 and webpack@5. Please refer to the [official migration guide](https://webpack.js.org/migrate/5/) for assistance.

Webpack 5 does not include polyfills for node.js core modules by default (e.g. `buffer`, `stream`, `os`). This can result in failed builds for plugins. If polyfills are required it is recommended to create a custom webpack config in the root of the plugin repo and add the required fallbacks:

```js
// webpack.config.js

module.exports.getWebpackConfig = (config, options) => ({
  ...config,
  resolve: {
    ...config.resolve,
    fallback: {
      os: require.resolve('os-browserify/browser'),
      stream: require.resolve('stream-browserify'),
      timers: require.resolve('timers-browserify'),
    },
  },
});
```

Please refer to the webpack build error messages or the [official migration guide](https://webpack.js.org/migrate/5/) for assistance with fallbacks. Issue [#47826](https://github.com/grafana/grafana/issues/47826)

We have changed the internals of `backendSrv.fetch()` to throw an error when the response is an incorrect JSON.

```javascript
// PREVIOUSLY: this was returning with an empty object {} - in case the response is an invalid JSON
return await getBackendSrv().post(`${API_ROOT}/${id}/install`);

// AFTER THIS CHANGE: the following will throw an error - in case the response is an invalid JSON
return await getBackendSrv().post(`${API_ROOT}/${id}/install`);
```

**When is the response handled as JSON?**

- If the response has the `"Content-Type: application/json"` header, OR
- If the backendSrv options ([`BackendSrvRequest`](https://github.com/grafana/grafana/blob/e237ff20a996c7313632b2e28f38032012f0e340/packages/grafana-runtime/src/services/backendSrv.ts#L8)) specify the response as JSON: `{ responseType: 'json' }`

**How does it work after this change?**

- In case it is recognised as a JSON response and the response is empty, it returns an empty object `{}`
- In case it is recognised as a JSON response and it has formatting errors, it throws an error

**How to migrate?**
Make sure to handle possible errors on the callsite where using `backendSrv.fetch()` (or any other `backendSrv` methods). Issue [#47493](https://github.com/grafana/grafana/issues/47493)
