 # @rocket/engine
 
+## 0.2.6
+
+### Patch Changes
+
+- 8dedc56: Add `engine.getVersion()` method
+- 390335d: Improve title tag handling
+
+## 0.2.5
+
+### Patch Changes
+
+- 93503ed: HTML in headings will be ignored for the menu
+  Some examples:
+
+  - `<h1>Hello <em>Word</em></h1>` => `Hello Word`
+  - `<h1>Hello <strong>World</strong> of <span>JS <em>(JavaScript)</em></span>!</h1>` => `Hello World of JS (JavaScript)!`
+
+- 3032ba9: Menus now support special characters in markdown headings.
+
+  Examples:
+
+  ```md
+  # Fun Errors & Feedback
+
+  # &lt;some-button>
+  ```
+
+## 0.2.4
+
+### Patch Changes
+
+- 09a47b4: Prevent fatal error because of simultaneous write to file.
+
+  When the browser requested a file to be rendered and that file also needed an update in the "rocket header" (the top of the file) then it could be that the watcher trigger a simultaneous render of the file while the first render was still in progress.
+
+  The solution is that the watcher ignores changes to a file until a full render is finished.
+
+## 0.2.3
+
+### Patch Changes
+
+- 379f08f: Remove the lit workaround to globally load the `global-dom-shim` in the "main thread".
+  Which means only the worker that does the actual SSR rendering will load it.
+
+## 0.2.2
+
+### Patch Changes
+
+- 6f88d8e: Get rid of the `rehype-prism` workaround by using latest esm version of mdjs that uses `rehype-prism-plus`
+- Updated dependencies [35ed64d]
+- Updated dependencies [6f88d8e]
+  - @mdjs/core@0.20.0
+
+## 0.2.1
+
+### Patch Changes
+
+- 367529c: Make sure user provided content in the folder `site/public/*` wins over public folders content provided by plugins.
+
 ## 0.2.0
 
 ### Minor Changes
