v1.38.2

🚀 Updates

• More plugin pre-loading improvements.

🐞 Fixes

• Potential fix for duplicate nodes in the action graph.
• Potential fix for the node platform panicing for a missing package manager.
• Potential fix for a fs rename error when installing proto.
• Fixed a panic that would occur during moon ci job calculation.

v1.38.1

🚀 Updates

• Added a new setting for toolchain plugins, versionFromPrototools, which controls how we inherit
  a version from the root .prototools file. By default this is enabled, but can be disabled, and configured with
  a string if the IDs don't match.
• Added support for toolchain plugins to replace/wrap a task script in the extend_task_script WASM
  API.
• Updated toolchain setup to preload the proto WASM plugin. This should help to alleviate network
  race conditions.
• Updated moon setup to also install toolchain plugins.

🐞 Fixes

• Fixed an issue where toolchain plugins do not inherit versions from .prototools.
• Fixed an issue where a file lock would be created for proto installation, even when it didn't need
  to be installed.
• Fixed an issue where moon docker prune would force install all toolchains. If you were relying
  on this functionality, run moon docker setup instead.

🧩 Plugins

• WASM API
  • Added ExtendTaskScriptOutput.script field.

  notifier.terminalNotifications setting in .moon/workspace.yml.
• Added a notifier.webhookAcknowledge setting, that ensures webhooks resolve with a 2xx status
  code.

🔖 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.
