We are excited to announce the release of **Astro-COLIBRI v2.19.0** , packed with new features and enhancements for transient astronomy and catalog exploration.

**📈 Enhanced Lightcurves for Optical Transients**

- **Combination of multiple ATLAS observations** for better data integration and visualization.
- **Upper limits added** for both **ATLAS** and **ZTF** observations.
- **Custom lightcurves** are now available for any sky position, independent of transient events.
- Integration of data collected by the **#RAPAS amateur astronomer network** (restricted to RAPAS members).
- Details in our [documentation](https://astro-colibri.science/lightcurvedoc)

**📚 TeVCat and 4FGL-DR4 Catalog Updates**

- **TeVCat** and **4FGL-DR4** databases updated to the latest versions.
- Including new plots:
  - **Beta vs Energy Peak** for 4FGL sources with significance \> 20.
  - **Flux vs Spectral Index** for TeVCat sources containing this information.

**🛠 Minor Improvements and Bug Fixes**

- **Team page updated** on our [website](https://astro-colibri.science/team).
- Added link to the **Lasair broker** for ZTF-detected transients.
- Improved handling of **confidential information requests**.
- **Restricted group for CTAO/LST-1** users, including submission of ToO requests.
- New **JSON download button** for selected event information.
- Observatories and Filters lists are now **scrollable** on smaller screens.
