+## Version 1.25
+
+### New .runsettings file support
+
+`Microsoft.Playwright.NUnit` and `Microsoft.Playwright.MSTest` will now consider the `.runsettings` file and passed settings via the CLI when running end-to-end tests. See in the [documentation](https://playwright.dev/dotnet/docs/test-runners) for a full list of supported settings.
+
+The following does now work:
+
+```xml
+<?xml version="1.0" encoding="utf-8"?>
+<RunSettings>
+  <!-- Playwright -->  
+  <Playwright>
+    <BrowserName>chromium</BrowserName>
+    <ExpectTimeout>5000</ExpectTimeout>
+    <LaunchOptions>
+      <Headless>true</Headless>
+      <Channel>msedge</Channel>
+    </LaunchOptions>
+  </Playwright>
+  <!-- General run configuration -->
+  <RunConfiguration>
+    <EnvironmentVariables>
+      <!-- For debugging selectors, it's recommend to set the following environment variable -->
+      <DEBUG>pw:api</DEBUG>
+    </EnvironmentVariables>
+  </RunConfiguration>
+</RunSettings>
+```
