v0.14.0

General

• Created new maelstrom-admin program. This program is minimal right now. It
  provides a subcommand that allows one to stop a Maelstrom cluster, which is
  useful for CI. It will definitely get more administrative functionality over time.
  [494]
• Created GitHub actions for
  maelstrom-broker,
  maelstrom-worker,
  cargo-maelstrom,
  maelstrom-go-test,
  maelstrom-pytest,
  and maelstrom-admin.
  [483]
• Created an example
  repository that
  has examples of how to configure Maelstrom
  for individual tests as well as how to use Maelstrom in CI.

  [491]
• Made many improvements to the GitHub integration:
  • Clients can now communicate with the broker over the GitHub artifact store,
    just like workers. This lets us run the broker in a different job than the
    clients. This in turn lets us build a better GitHub action for the broker,
    as well as the workflow have many different jobs run in parallel and
    interact with the cluster.

  • Unified the configuration values used by Maelstrom programs on GitHub.

All Test Runners (cargo-maelstrom, maelstrom-go-test, and maelstrom-pytest)

• Made --watch flag visible in help.
• Gave --watch a -w short option.
• Gave --repeat a -t short option.
  [482]
• Gave --stop-after a -s short option.
  [482]
• Gave --list (--list-tests) a -l short option.
  [513]

All Clients (Test Runners, maelstrom-run, and Client Library)

• Fix an issue where we wouldn't find a matching image in some OCI images on
  ARM64 (like docker://alpine).
  [506]

All Programs

• Changed the short option for --log-level to -L instead of -l.
  [513]
• Added support for generic Maelstrom environment variables, like
  MAELSTROM_BROKER in addition to program-specific ones like MAELSTROM_PYTEST_BROKER.
  [492]

maelstrom-worker

• Fixed a test that would fail with RUST_BACKTRACE=1.
