Hi everyone,

We are excited to announce the release of **Astro-COLIBRI v2.28.0**! This update brings a suite of new features again designed to improve observation planning, mobile immersion, and our integration with the global Virtual Observatory (VO) ecosystem.

Here are the highlights of this version:

### 📱 Enhanced Augmented Reality ([Astro-COLIBRI AR](https://astro-colibri.science/ar_mode))

The AR mode has received a significant upgrade in both stability and precision. In addition, we implemented:

- **Screenshots:** You can now capture your AR view using a dedicated in-app button. Images are saved locally for easy sharing.
- **Direct AR Links:** You can now share links that load a specific event directly into AR mode, making it easier to show colleagues or friends where to look in the sky.
- **Free trial:** You can now try the AR features for free during a one-week free trial period. Try it yourself at: [Astro-COLIBRI](https://astro-colibri.com/subscription)

### 🗓 Advanced Visibility & Observation Planning

We’ve overhauled our visibility tools to help you plan your nights more effectively:

- **Multi-Source Assessment:** A new API endpoint (`visibility_plot_multi_source`) and interface allow you to calculate and compare visibility windows for multiple sources simultaneously. This is a game-changer for scheduling complex observation nights.
- **Long-term Planning:** The long-term visibility plots now feature configurable start and end dates.
- **Streamlined API:** We’ve unified the naming conventions for visibility endpoints (rest assured, legacy names will remain supported until mid-2026).

### 🌐 Web-Browser Notifications

You can now receive real-time alerts for new transient events directly in your web browser. No worries, we will not spam you: you have to activate them yourself 😉

- **Sync:** Settings can be synchronized with your mobile notification preferences.
- **Smart Filtering:** In all notifications, we’ve implemented logic to avoid duplicate notifications if you are subscribed to multiple overlapping streams.

### 🔭 Further Virtual Observatory (VO) Integration

Astro-COLIBRI is now even more interoperable with professional tools like ALADIN:

- **A++ Compliance:** Our IVAO “_Simple Cone Search_” endpoint has been validated with the highest level of IVOA compliance and is officially registered.
- **Standard Formats:** You can now download events as _VoEvents_ and lightcurves as _VOTables_ directly via the web interface or our new API endpoints.

### 🛠 Other Notable Improvements

- **Custom Events:** You can now create your own events and save them to your personal watchlist.
- **Landscape Mode:** The mobile interface now features a timeline view when held in landscape mode.
- **GRB Updates:** Improved redshift consistency across multiple instruments and a new redshift filter for GRBs.
- **Apple Login:** Support for signing in with Apple iCloud accounts (in addition to the Google signin).

As always, this update includes a range of bug fixes and performance “behind-the-scenes” updates to ensure the smoothest experience possible.

We look forward to hearing your feedback!

Clear skies,  
The Astro-COLIBRI Team
