# December 29th, 2024

Hi there, Storylaners! 👋

As we close out the year, we’re excited to deliver one final set of updates to make your demos more seamless and insightful.

### 🚀 **Time-Based Trigger: Step Autoplay for Smoother Navigation**

Keep your audience engaged without manual clicks! With the new **Trigger function** in both **screenshot demos** and **HTML demos**, guides can now progress automatically after a set period of time.

* **Where to Find It:** Edit guide > Trigger.
* **How It Works:** Once added, the guide moves forward automatically after the defined duration.
* **Available In:** Hotspots and Tooltips.

### 📊 **Chapter-Level Insights with GA and Cross-Frame Events**

We’re now sending **sl\_chapter\_start** and **sl\_chapter\_end** events to Google Analytics and as Cross-Frame events. We will be deprecating flow events soon.

* **New Events:** `sl_chapter_start`, `sl_chapter_end`
* **Deprecating Soon:** `flow_start` and `flow_end`

### 🖼️  **WebP Image Support**

You can now upload **WebP images** directly into your demos. Smaller file sizes and faster load times – it’s a win-win-win! 

Why WebP? Better compression, reduced loading time, and clearer visuals.

Stay cool and happy demoing! ✌️
