← 5.4.0 | 5.2.4 → | ↑ 5.x series

Added

Configs - BaseConfig

• APP_NAME identity field - Top-level APP_NAME is now a built-in BaseConfig setting (env: APP_NAME). On set_global(), customize() fills nested identity defaults when they are still unset or placeholders:
  • OTEL.SERVICE_NAME when None
  • FASTAPI.PROJECT_NAME when "project_name"
  • AUTH.JWT_ISSUER when "your-app-name"
  • TEMPORAL.CLIENT_IDENTITY when None
  • Explicit nested env values (OTEL__SERVICE_NAME, etc.) always win

Tests

Tests - Configs

• APP_NAME sync BDD - Scenarios assert nested identity fill on set_global and that explicit OTEL.SERVICE_NAME overrides are kept.
