withMetadata param deprecated; mounts field renamed from volume to drive

BreakingBreaking change

This is a breaking change — integrations that rely on the affected behaviour will need updates before the change rolls out.

What changed

Two distinct changes are present:

  • withMetadata query parameter on at least two feature-flag list endpoints is now formally deprecated ("deprecated": true), with guidance to resolve creator identity client-side and use the single-flag lookup endpoint instead. Existing integrations relying on this parameter should migrate before it is removed.
  • mounts[*].volume field renamed to drive in a sandbox-related response schema. This is a breaking rename: the volume property is removed from the required fields and replaced by drive, so any client reading mounts[*].volume will receive undefined/null at runtime.
