05.09.2025: Annotations, Data Retention Policies, Hotkeys 📓
Phoenix v9.0.0 release brings major updates to annotation support, and a whole host of other improvements.
Annotations 🏷️
Up until now, Phoenix has only supported one annotation of a given type on each trace. We've now unlocked that limit, allowing you to capture multiple values of an annotation label on each span.
In addition, we've added:
API support for annotations - create, query, and update annotations through the REST API
Additional support for code evaluations as annotations
Support for arbitrary metadata on annotations
Annotation configurations to structure your annotations within and across projects
Data Retention 💿
Now you can create custom global and per-project data retention polices to remove traces after a certain window of time, or based on number of traces. Additionally, you can now view your disk usage in the Settings page of Phoenix.
Hotkeys 🔥
We've added hotkeys to Phoenix!
You can now use j and k to quickly page through your traces, and e and n to add annotations and notes - you never have to lift your hands off the keyboard again!
