This integration allows developers to easily add distributed tracing and metrics to their FastAPI applications without third-party middleware. The release also includes several refactors, documentation improvements, and updated translations.
- Native OpenTelemetry support added via PR #16403 by @tiangolo. This enables seamless integration with OpenTelemetry for observability.
- Improved mobile responsiveness of the conference rail (PR #16196 by @alejsdev).
- Removed conf section and added event banner (PR #16193 by @alejsdev).
- Removed unused image from docs (PR #16195 by @alejsdev).
- Used buttons for Termynal controls to enhance accessibility (PR #16132 by @tiangolo).
- Updated translations for multiple languages: hi, ru, zh-hant, uk, de, tr, ja, fr, zh, es, pt (PRs #16212, #16210, #16211, #16208, #16209, #16207, #16206, #16205, #16204, #16203, and more).
For developers, the native OpenTelemetry support is a significant addition.
