#### Tilepy 2.0 released!

We are excited to announce the release of **Tilepy 2.0** , our open-source Python package that optimizes and facilitates the scheduling of follow-up observations of multi-messenger events like gravitational waves and gamma-ray bursts. Developed over the past eight years by our team of researchers at IRFU/CEA Paris-Saclay, Tilepy is already established as the default scheduling tool for multi-messenger studies at the international H.E.S.S. and CTA/LST-1 observatories.

**Key features of Tilepy 2.0:**

- Optimized observation scheduling considering telescope visibility and observability constraints.
- Versatile application to support various poorly localized transient events.
- Seamless integration with the Astro-COLIBRI platform for a user-friendly interface for scheduling observations.
- Easy-to-use but flexible and customizable architecture that can be tailored to specific instruments, collaborations and individual requirements.

#### Tilepy 2.0 est arrivé !

Nous sommes ravis d’annoncer la sortie de **Tilepy 2.0** , notre paquet Python open-source qui optimise et facilite la planification des observations de suivi des événements multi-messagers tels que les ondes gravitationnelles et les sursauts gamma. Développé au cours des huit dernières années par notre équipe de chercheurs de l’IRFU/CEA Paris-Saclay, Tilepy s’est déjà imposé comme l’outil de planification par défaut pour les études multi-messagers dans les observatoires internationaux H.E.S.S. et CTA/LST-1.

**Principales caractéristiques de Tilepy 2.0 :**

- Planification optimisée des observations en tenant compte de la visibilité du télescope et des contraintes d’observabilité.
- Application polyvalente pour prendre en charge divers événements transitoires mal localisés.
- Intégration transparente avec la plateforme Astro-COLIBRI pour une interface conviviale permettant de planifier les observations.
- Architecture facile à utiliser, mais flexible et personnalisable, qui peut être adaptée aux besoins spécifiques de chaque instrument, collaboration et des individus.
