📄 Description

  • previously when channels were cleared via update([]) or consume() that would not bump the version
  • that behavior is not compatible with checkpointers that store blobs separately, which join checkpoint and blobs using version
  • now update() and consume() return bool to indicate if version should be bumped
  • this also avoids bumping version when nothing changed
