v3.0.1

• Improved supported for Circle 2.0 (#42).
  • CIRCLE_WORKFLOW_WORKSPACE_ID is now used as the parallel nonce if PERCY_PARALLEL_NONCE is not specified. This gives a better default higher-level grouping for snapshots when tests are parallelized in Circle, otherwise it has no effect. We believe this change is backwards compatible, but please reach out if you have issues.
