v1.37.0

🔖 RFCs

• Task input additions and enhancements: #1985

🚀 Updates

• Added a new Rust toolchain implementation, powered entirely by our new WASM plugin system. Since toolchain plugins are new and unstable, this Rust toolchain can be enabled with the unstable_rust identifier (instead of rust).
  • Supports multiple Cargo workspaces, and workspaces can exist at any depth.
  • More accurate project relationship detection.
  • New addMsrvConstraint setting.
  • Better Docker prune implementation.
  • Improved manifest/lockfile parsing.
  • Cargo/rustup commands are now hashed and cached.
• Added an unstable moon mcp command, which starts an MCP (model context protocol) stdio server
  that responds to AI agent requests.
  • Supports the following tools: get_project, get_projects, get_task, get_tasks.
  • We will be expanding this with more functionality over time, like run_task, etc.
• Updated webhook events.
  • Added environment.initializing and environment.initialized events.
  • Added root and toolchain fields to dependencies.installing and dependencies.installed
    events.
  • Deprecated the runtime field in all events. Will be removed once toolchain plugins are
    complete.

🧩 Plugins

• Added test utilities for testing toolchain plugin functions.
• Improved cache handling and invalidation for SetupEnvironment and InstallDependencies actions.
• WASM
  • Reworked all virtual path fields in "output" structs to greatly reduce the JSON payload.
  • Reworked the ManifestDependency type to be an enum instead of a struct.
  • Added ProjectDependency.via field.

⚙️ Internal

• Updated proto to v0.49.4 (from 0.49.1).
• Updated dependencies.

v1.36.3

🐞 Fixes

• Fixed an issue where environment variables with default/fallback values (${VAR:+default}) were
  not parsed correctly.

⚙️ Internal

• Updated dependencies.

v1.36.2

🚀 Updates

• Added support for shell-specific environment variable namespaces when scanning and substituting
  values. Supports the following:
  • $E: - Elvish
  • $env:: - Ion
  • $ENV. - Murex
  • $env. - Nu
  • $env: - PowerShell
• Updated all identifiers to support unicode alpha-numeric characters instead of just ASCII.

🐞 Fixes

• Fixed some issues where MOON_TOOLCHAIN_FORCE_GLOBALS wasn't respected for Python and Rust
  toolchains.

v1.36.1

🐞 Fixes

• Fixed an issue where tasks would not substitute environment variables when executing, because it
  did not run in a shell.

⚙️ Internal

• Updated dependencies.

v1.36.0

🚀 Updates

• Added more unstable support for toolchain plugins.
  • In the project graph:
    • Extend projects with dependencies, tasks, and an alias.
  • In the action pipeline:
    • Added SetupEnvironment action that executes the setup_environment WASM API.
    • Added InstallDependencies action that executes the install_dependencies WASM API.
  • When running tasks:
    • Extend the command/script with additional parameters before executing.
    • Inject dependency and lock information into the hash.
  • With Docker:
    • Updated docker prune to utilize the new WASM APIs for toolchain plugins.
• Added --host and --port options to moon action-graph, moon task-graph, and
  moon project-graph.
• Added --stdin option to moon ci and moon run, which will allow touched files to be passed
  via stdin, instead of running VCS commands to determine them.
  • This is a follow-up fix to the revert in a previous version. This functionality is now opt-in
    instead of the default, to avoid problematic edge cases.
• Updated and improved remote caching:
  • Added an unstable_remote.cache.verifyIntegrity setting, that will verify the digest of
    downloaded blobs to ensure they aren't corrupted or incomplete. Will degrade performance but
    ensure reliability.
  • Added a file rollback mechanic to that will be triggered when hydration fails part way and
    written files need to be removed.
  • Updated blob existence checks to be batched and parallelized.
  • Can now be enabled entirely through environment variables.
• Updated and improved code generation:
  • Added support for array and object variable types in template.yml. The values must be JSON
    compatible.
  • Updated generator.templates to support https:// URLs that point to an archive that can be
    unpacked.
• Removed the restriction around moon.{yml,pkl} not being allowed as a task input. However, will
  not be included when using **/*.

🐞 Fixes

• Fixed an issue where terminal prompt validation would not trigger.
• Fixed an issue with remote cache hydration where multiple files with the same blob hash would fail
  to write them all.
• Fixed an issue where changing args or env of a task dependency would not invalidate its cache.
• Fixed an issue where environment variables passed on the command line would not overwrite task
  env.
• Fixed tag-based task dependencies not creating implicit project dependencies.
• Fixed some task/command argument quoting issues.

🧩 Plugins

• Added new toolchain WASM APIs.
  • extend_project_graph - Extend projects with toolchain specific info.
  • extend_task_command - Extend the command child process with parameters.
  • extend_task_script - Extend the script child process with parameters.
  • locate_dependencies_root - Locate the package dependencies workspace root.
  • parse_manifest - Parse a manifest file to extract dependencies.
  • parse_lock - Parse a lock file to extract resolved dependencies.
• WASM
  • Added InstallDependenciesInput.packages and production fields.
  • Added InstallDependenciesOutput.operations field.
  • Added PruneDockerInput.projects and root fields.
  • Added PruneDockerOutput.
  • Added SetupEnvironmentOutput.operations field.
  • Added SetupToolchainOutput.operations field.
  • Added SyncWorkspaceInput.toolchain_config field.
  • Added TeardownToolchainInput.version field.

⚙️ Internal

• Updated Rust to v1.87.0.
• Updated proto to v0.49.1 (from 0.47.11).

v1.35.7

🐞 Fixes

• Reverted moon ci and moon run accepting touched files via stdin, as it's causing issues in CI
  environments. Will revisit for the next release.

v1.35.6

🚀 Updates

• Updated moon run to support passing touched files via stdin.
• Updated commands that wait for stdin to continue after 10 seconds if nothing was received.

🐞 Fixes

• Fixed an issue where Git v2 would error loading submodules that haven't been checked out yet.
• Fixed an issue with remote cache hydration that would leave around stale artifacts.
• Fixed an issue where parallel persistent tasks wouldn't prefix output.

v1.35.5

🐞 Fixes

• Potential fix for affected dependencies in the action pipeline not running and failing with a
  "missing hash" error.
• Potential fix for "Bun" and "Node with Bun as a package manager" both installing dependencies in
  parallel and colliding.
• Fixed an issue where downloading an invalid remote cache would not abort the hydrate process.
