+
+## Overview of Breaking Changes
+
+Welcome to version 11.0.  This a major release and therefore contains breaking changes.  Below is a complete list of those such changes.
+
+
+### Built-in set of "Common" Languages
+
+The default `highlight.min.js` build **removes** a few less popular grammars:
+
+- apache
+- http
+- nginx
+- properties
+- coffeescript
+
+If you need any of these, you can always create a custom build.
+
+Ref: https://github.com/highlightjs/highlight.js/issues/2848
+
+
+### Language Files
+
+This would matter if you are requiring any of these files directly (via Node.js or CDN).
+
+- `htmlbars` has been removed. Use `handlebars` instead.
+- `c-like` has been removed. Use `c`, `cpp`, or `arduino`.
+- `sql_more` has been removed. Use `sql` instead.
+
+
+### Language Aliases
+
+This would matter if you are using these aliases.
+
+- `php3`,`php4`,`php5`, `php6`, `php7`, and `php8` havbe been removed. Use `php` instead.
+- `zsh` has been removed. Use `sh` or `bash` instead.
+- `freepascal`, `lazarus`, `lpr`, and `lpm` removed. Use `delphi` instead.
+
+You can of course re-register any of these aliases easily if necessary. For example to restore the PHP aliases:
+
+```js
+hljs.registerAliases(["php3","php4","php5","php6","php7","php8"],{ languageName: "php" })
+```
+
+### Styles and CSS
+
+- The default padding on `.hljs` element has been increased and is now `1em` (it was `0.5em` previously). If your design depends on the smaller spacing you may need to update your CSS to override.
+- `schoolbook` no longer has a custom lined background, it is solid color now.  The old image and CSS can be found in the [10-stable branch](https://github.com/highlightjs/highlight.js/tree/10-stable/src/styles) if you wish to manually copy it into your project.
+- `github` includes significant changes to more properly match modern GitHub syntax highlighting. If you desire the old theme you can manually copy it into your project from the [10-stable branch](https://github.com/highlightjs/highlight.js/tree/10-stable/src/styles).
+
+
+### Behavioral changes
+
+#### API changes
+
+- The `highlight(language,code, ...args)` API no longer accepts `continuation` as a 4th argument.
+- The `highlight(language,code, ...args)` API is deprecated (to be removed in 12.0).
+
+The new call signature is `highlight(code, {options})`. ([see docs](https://highlightjs.readthedocs.io/en/latest/api.html#highlight))
+
+Code using the old API:
+
+```js
+// highlight(language, code, ignoreIllegals, continuation)
+highlight("javascript", "var a = 5;", true)
+```
+...would be upgraded to the newer API as follows:
+
+```js
+// highlight(code, {language, ignoreIllegals})
+highlight("var a = 5;", {language: "javascript", ignoreIllegals: true})
+```
+
+The new API purposely does not support `continuation` as this is only intended for internal library usage.
+
+- `initHighlighting()` is deprecated (to be removed in 12.0).
+- `initHighlightingOnLoad()` is deprecated (to be removed in 12.0).
+
+**Use `highlightAll()` instead.** ([see docs](https://highlightjs.readthedocs.io/en/latest/api.html#highlight-all)) The old functions are now simply aliases of `highlightAll()`. The new function may be called before or after the DOM is loaded and should do the correct thing in all cases, replacing the need for the previous individual functions.
+
+Note: `highlightAll()` does not guard against calling itself repeatedly as the previous functions did. Your code should be careful to avoid doing this.
+
+- `highlightBlock()` is deprecated (to be removed in 12.0).
+
+**Use `highlightElement()` instead.** ([see docs](https://highlightjs.readthedocs.io/en/latest/api.html#highlight-element)) This is merely a naming change.
+
+Note: The object literal passed to the `before:highlightElement` callback now passes the element in the `el` key vs the `block` key.
+
+##### Changes to Result Data
+
+- `highlightAuto()`'s `second_best` key has been renamed to `secondBest`
+- `highlightElement()`'s result now no longer includes a `re` key. Use the `relevance` key now.
+- `highlight()` renames some result keys to more clearly mark them as private: `_top`, `_emitter`, and `_illegalBy`. You should not depend on these keys as they are subject to change at any time.
+- The `relevance` key returned by `highlight()` is no longer guaranteed to be an even integer.
+
+
+#### Feature Removal
+
+- HTML auto-passthru is now no longer included in core.  Use a plugin instead. For a possible plugin please see [#2889](https://github.com/highlightjs/highlight.js/issues/2889).
+
+An example:
+
+```html
+<pre><code class="lang-js">
+var a = 4;
+<span class="yellow">var a = 4;</span>
+</code></pre>
+```
+
+Unescaped HTML like this will now be ignored (stripped before highlighting) and a warning will be logged to the console.  All HTML to be highlighted should be properly escaped to avoid potential HTML/JS injection attacks.
+
+- `fixMarkup` has been removed.
+
+This function was deprecated in v10.2.  It is not our goal to provide random string utilities. You may need to provide your own replacement [Ref: #2534](https://github.com/highlightjs/highlight.js/issues/2634)
+
+- `CSS_NUMBER_MODE` has been removed.
+
+This rule was too broad for bring inclusion in core and has been removed.
+
+- `useBR` configuration has been removed.
+
+This configuration option was deprecated in v10.1. Use a plugin or preferably simply CSS `white-space: pre`. [Ref: #2559](https://github.com/highlightjs/highlight.js/issues/2559)
+
+
+- `tabReplace` configuration has been removed.
+
+This configuration option was deprecated in v10.5. Use a plugin or pre-render content instead with desired spacing. [Ref: #2874](https://github.com/highlightjs/highlight.js/issues/2874)
+
+
+
+
+
+### Small Things
+
+- The `regex` utility `join` has been renamed to `_eitherRewriteBackreferences` (this has always been intended for internal use only)
