Release 0.4.1

[Michaelvll]

• pytest tests/test_smoke.py
• pytest tests/test_smoke.py --aws
• locally build docs, open docs/build/index.html, scroll over “CLI Reference” (ideally, every page) to see if there are missing sections (we once caught the CLI page completely missing due to an import error; and once it has weird blockquotes displayed)
• Check sky -v
• backward_compatibility_tests.sh run against 0.4.0.
• Run manual stress tests (see subsection below)
  • following script

    sky spot launch --gpus A100:8 --cloud aws echo hi -y
    # Check we are properly failing over the zones:
    sky spot logs --controller
    

  • following script

    sky launch -c dbg --cloud aws --num-nodes 16 --cpus 2+ --down echo hi  # without timeout bump
    sky down dbg  
    

  • following script

    sky launch -c dbg --cloud aws --num-nodes 16 --gpus T4 --down --use-spot echo hi
    sky down dbg
    

  • following script (16 nodes do not work with GCP due to the autoscaler bug of ray)

    sky launch -c dbg --cloud gcp --num-nodes 8 --cpus 2+ --down  echo hi# with or without timeout bump
    sky down dbg  
    

  • following script

    # Run a 24-hour+ spot job and ensure it doesn’t OOM
    # https://github.com/skypilot-org/skypilot/pull/2675
    sky spot launch -n test-oom --cloud aws --cpus 2 sleep 86400
