v1.38.6

🧰 Toolchains

• Go
  • Fixed go.* parsing failures when there was no trailing newline.

⚙️ Internal

• Updated proto to v0.50.5 (from 0.50.1) to resolve an "unknown field spec" error. This is triggered when the global proto binary is using v0.51, and moon is using proto < v0.50.5.

v1.38.5

🚀 Updates

• Updated project locating to log the glob results for debugging purposes.

🐞 Fixes

• Fixed a bun.lock parsing error.

v1.38.4

🚀 Updates

• Updated MCP (Model Context Protocol) implementation to use protocol version 2025-06-18 from
  2025-03-26 - in turn, allowing Claude Code to use the MCP.
  • Updated sync_projects tool to sync all projects if no IDs provided.

📚 Documentation

• Added Claude Code to MCP documentation.

v1.38.3

🐞 Fixes

• Fixed the duplicate nodes in the action graph.

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.

v1.38.0

💥 Breaking

• WASM API
  • Renamed RegisterToolchainOutput.lock_file_name to RegisterToolchainOutput.lock_file_names
    and its type to Vec<String>.
  • Renamed RegisterToolchainOutput.manifest_file_name to
    RegisterToolchainOutput.manifest_file_names and its type to Vec<String>.

🚀 Updates

• Added a new Go toolchain implementation, powered entirely by our new WASM plugin system. It can be enabled with the unstable_go identifier.
  • Supports tiers 1, 2, and 3!
  • Supports Go workspaces via go.work files.
  • Extracts project dependencies and relationships from go.mod files.
  • Extracts version and lockfile information from go.sum and go.work.sum files.
  • Basic vendor support (go mod vendor) during Docker prune.

  • get_touched_files - Gets touched files between base and head.
  • sync_projects - Runs the SyncProject action for one or many projects.
  • sync_workspace - Runs the SyncWorkspace action.
• Added new moon toolchain command and sub-commands.
  • Add a toolchain to .moon/toolchain.yml with moon toolchain add.
  • View information about a toolchain plugin with moon toolchain info.
• Added support for terminal desktop notifications. Can be enabled with the new
  notifier.terminalNotifications setting in .moon/workspace.yml.
• Added a notifier.webhookAcknowledge setting, that ensures webhooks resolve with a 2xx status
  code.
• Updated project graph invalidation to take manifests from toolchain plugins into account.

🐞 Fixes

  when cleaning stale files.
