 ### Customizing Styles
 
-The preferred method for overriding the pre-defined styles in the library is to two step process. First, import our bundled CSS into the file where you instantiate your chat application. Second, locate any Stream styles you want to override using either the browser inspector or by viewing the library code. You can then add selectors to your local CSS file to override our defaults.

+### Removal of Window's hideOnThread prop
+
+The prop boolean `hideOnThread` enabled us to control, whether class `str-chat__main-panel--hideOnThread` was attached to `Window` component's root `<div/>`. By assigning this class a CSS rule `display: none` in the default SDK's stylesheet we hid the contents of `Window`. We decided to simplify the logic in this case:
+
+1. class `str-chat__main-panel--hideOnThread` was replaced by class `str-chat__main-panel--thread-open`
+2. the class `str-chat__main-panel--thread-open` is attached to the root `<div/>` always, when thread is open
+3. the default value of `hideOnThread` prop was `false` (`Window` contents was not hidden upon opening a thread) and so integrators still have to opt in to hiding the contents upon opening a thread by adding rule `display: none` to `str-chat__main-panel--thread-open` class
+
+:::important
+**Action required**
+If your application renders `Window` with `hideOnThread` enabled, and you want to keep this behavior add the following rule to your CSS:
+
+```css
+.str-chat__main-panel--thread-open {
+  display: none;
+}
+
+.str-chat__main-panel--thread-open + .str-chat__thread {
+  // occupy the whole space previously occupied by the main message list container
+  flex: 1;
+}
+```

+
+### Removal of Thread's fullWidth prop
+
+Setting the `fullWidth` value to `true` let to assignment of class `str-chat__thread--full` to the `Thread` component's root `<div/>`. This class had support in the SDK's legacy stylesheet only. With the approach of avoiding styling React components via props, the prop has been removed along with the legacy stylesheet.
