# Release Notes — June 2026

### 🚀 New Features

🚀 \[Calculations] French hotel methodology (NOS-GESTES-CLIMAT) A new ADEME-based hotel emission methodology is available across the API, dashboard, settings, and report builder. It uses a simple fixed factor per hotel night for clients aligning with French national standards.

🚀 \[Data Accuracy] DEFRA 2026 emission factors The UK Government's updated 2026 greenhouse gas conversion factors are now live for flights, trains, buses/coaches, and cars. Clients using DEFRA methodology receive the latest official figures automatically — no action required.

### 📈 Improvements

📈 \[Data Accuracy] Smarter train type mapping Switching between train emission methodologies in settings now automatically maps the correct train type, removing a source of validation errors and manual cleanup.

📈 \[API] Broader flight API support The flight calculation API now handles unresolved or masked airline codes gracefully, returning a valid result instead of an error.

📈 \[Stability] Security patches applied Applied routine security updates to keep the platform secure. No client action required.

### 🐞 Bugfixes

🐞 \[Dashboard] Overview page filters restored Fixed an issue where filters on the reporting overview page had stopped working correctly.
