+Love numbers? You'll love Serenity/JS 3.29! 🎉
+
+We’re excited to share the latest release of Serenity/JS, which is packed with new powerful features for handling numeric data in your automated tests!
+
+
+
+## New to Serenity/JS?
+
+Serenity/JS web testing tutorial was called "the best guide if you want to take your automation skills to the next level." ❤️
+
+If you're new to Serenity/JS or web automation in general, start with ["Your first web scenario"](/handbook/web-testing/your-first-web-scenario/).
+
+## New in Serenity/JS 3.29
+
+### Built-in support for arithmetic operations
+
+Part of the [Serenity/JS Core module](/api/core/), the new [`Numeric`](/api/core/class/Numeric/) class offers built-in support for performing arithmetic operations
+on both synchronous and asynchronous data types directly within your Serenity/JS test scenarios.
+
+In addition, this new class offers methods to help you extract numeric data from REST API responses and web interfaces
+and convert it to a desired numeric data type without any external libraries or complex workarounds.
+
+This enhancement makes your tests more readable, reduces the risk of calculation errors, and ensures data-driven scenarios are both easy to implement and maintain.
+With `Numeric`, your test logic is cleaner, making Serenity/JS even more developer-friendly.
+
+Learn about [`Numeric`](/api/core/class/Numeric/).
+
+
+### More Serenity/JS examples in your IDE!
+
+We continue our effort to bring the thousands of examples available in the [Serenity/JS API documentation](/api/) close to you and your team.
+As part of that, the new [`Numeric`](/api/core/class/Numeric/) class ships with **15 new examples**, demonstrating how to extract numeric data from user interfaces and data objects.
+You'll also learn how to use the new features with [Serenity/JS Page Element Query Language](/handbook/web-testing/page-element-query-language/) to make extracting the right UI element even easier!
+
+Check out the Serenity/JS API docs at https://serenity-js.org/api/
+
+Enjoy Serenity!
