Breaking Changes

New Features

• Add flag to enable span size metrics reporting (@ymtdzzz in #3782)
  • Span size metrics are enabled via the --collector.enable-span-size-metrics flag (even if --collector.queue-size-memory is disabled).
• Add multi-tenancy support (@esnible in #3688)
  • Enabled when --multi_tenancy.enabled=true is passed to the collector.
  • The header carrying the tenants can be specified via the --multi_tenancy.header flag, which defaults to x-tenant.
