ReleasePort's take
Light signalOpik 2.0.30 removes TOGGLE_COLLABORATORS_TAB_ENABLED and TOGGLE_RUNNERS_ENABLED toggles. Includes fixes for LLM failure masking in experiment processing and annotation queue navigation.
Why it matters: Teams relying on TOGGLE_COLLABORATORS_TAB_ENABLED or TOGGLE_RUNNERS_ENABLED must plan migration before upgrading. Experiment processor now correctly surfaces LLM failures instead of masking them, improving debugging visibility.
