🐞 Fixes

• Fixed an issue where a task would try to execute with proto, but proto hasn't been fully installed
  yet.
• Fixed an issue where task PATHs may not always be injected correctly.

🧰 Toolchains

• JavaScript
  • Fixed some package.json dependency version parsing issues.

⚙️ Internal

• Updated dependencies.

💥 Breaking

• The legacy toolchains (bun, node, python, etc) will no longer automatically enable if there's a
  version defined in .prototools, as there's no way to differentiate between the legacy and modern
  toolchains.
• Updated moon query touched-files to default to comparing against remote branches when in CI, and
  local when not in CI. This aligns with the other moon query commands.
  • This can be overridden with the --local and --remote flags.

🚀 Updates

• Added new JavaScript ecosystem toolchain WASM plugins. This was a large feature that required
  extensive work, as the JavaScript ecosystem is quite unique. The following plugins are being
  introduced:
  • unstable_javascript
    • A new JavaScript specific plugin that is a superset of all JavaScript runtimes (Bun & Node,
      with Deno coming soon).
    • Implements tier 1 and 2 features, and is now in charge of defining the package manager,
      installing dependencies, extending the project graph (aliases and tasks), parsing
      lockfiles/manifests, and much more.
    • Supports multiple lockfiles for each package manager.
  • unstable_bun and unstable_node
    • The JavaScript runtimes only implement tier 1 and 3 features, and only exist for installing
      the tool into the proto toolchain. Most functionality is now in the unstable_javascript
      plugin.
    • Supports settings for Bun/Node execution.
  • unstable_npm, unstable_pnpm, and unstable_yarn
    • The JavaScript package managers only implement tier 1 and 3 features, and only exist for
      installing the tool into the proto toolchain. Most functionality is now in the
      unstable_javascript plugin.
    • Supports settings for package installation.
    • npm now supports npm-shrinkwrap.json.
    • Is no longer configured within node, and is now configured at the top-level within
      .moon/toolchain.yml.
• Added new values to the task cache option, alongside the existing boolean.
  • local to only use the local cache.
  • remote to only use the remote cache.
• Added a new unstable_remote.cache.localReadOnly setting, which turns local development caching
  into a read-only mode (only downloads, doesn't upload).
• Updated task commands (child processes) to utilize toolchain executables directly, instead of
  relying entirely on proto shims. It achieves this by locating the executables, and prepending
  their directory onto PATH.
• Updated moon task command to include all PATHs that are injected when running the task.
• Deprecated the moon run --profile option.
  • This option was only used by Node.js, and is now a configuration setting for the unstable_node
    toolchain.
• When running a task, we now set a MOON_TASK_HASH environment variable for the current hash,
  which can be read from child processes.
• Published the moon VS Code extension to Open VSX:
  https://open-vsx.org/extension/moonrepo/moon-console

🐞 Fixes

• Fixed an issue where proto shim/bin directories were always included in task command PATH, even
  when proto is not required.
• Fixed an issue with task options affectedFiles and runFromWorkspaceRoot generating invalid
  paths.
• Fixed moon docker file generating invalid Dockerfiles after the recent proto install changes.
• Fixed an issue where xz/liblzma was dynamically linked, instead of statically.

🧰 Toolchains

• Go
  • Fixed an issue with bins when installing multiple packages from different modules in parallel.
• Python
  • When running uv venv, we now include the --no-managed-python flag when the python.version
    setting is defined. This should ensure that moon/proto's Python managed version is used.
  • When running uv sync, we now include the --no-managed-python flag unless the
    python.uv.syncArgs setting is defined.
• Rust
  • Updated manifest parsing to extract path and git values from dependencies.
• TypeScript
  • When includeSharedTypes and syncProjectReferences are both enabled, and the shared types
    folder contains a tsconfig.json, it will also be synced as a project reference.

🧩 Plugins

• WASM API
  • Added a new define_requirements plugin API for tier 2.
  • Added DefineRequirementsInput and DefineRequirementsOutput types.
  • Added MoonContext.get_project_root and get_project_root_from_source methods.
  • Added ExtendProjectGraphInput.toolchain_config field.
  • Added ExtendTaskCommandInput.toolchain_config and project fields.
  • Added ExtendTaskScriptInput.toolchain_config and project fields.
  • Added load_toolchain_config and load_project_toolchain_config functions.
  • Added load_toolchain_config_by_id host function.

⚙️ Internal

• Updated proto to v0.52.3 (from 0.51.4).
• Updated Rust to v1.89.0.

🐞 Fixes

• Fixed an issue with moon setup failing when proto is not available.
• Fixed task input inferrence to not include the $HOME, $USER, and $PWD environment variables.
• Fixed some arg/shell quoting issues.

🐞 Fixes

• Fixed a regression where an unknown/unconfigured layer would trigger a violation error.

🐞 Fixes

• Fixed a glob input parsing issue when the pattern contained a ? and wasn't in URI format.
• Fixed JSON schemas not including property aliases (project type for layer, etc).

⚙️ Internal

• Updated dependencies.

🐞 Fixes

• Fixed a path error for @moonrepo/cli package.

🚀 Updates

• The automatic proto install has moved into a new SetupProto action, which is now part of the
  action graph, and does not run on every command. It's also a bit smarter and will only install
  when a toolchain requires it.
• Added support for new task input formats based on the RFC: #1985
  • Added URI support for files (file://) and globs (glob://).
  • Added object support for files and globs.
• Updated task input files:
  • Added a optional param, which allows the file to be optional (missing) during hashing.
    Defaults to true.
  • Added a content param, which will match against the file's contents to determine affected
    state.
• Updated task input globs:
  • Added a cache param, which controls whether the glob results should be cached or not.
• Updated the @moonrepo/cli npm package to no longer rely on postinstall scripts.
• Improved argument quoting for commands and scripts.
• Renamed project type to layer, as it better reflects what it does, a layer of access within
  the project stack. For backwards compatibility, the type name will still be supported until
  v2. The following changes have been made:
  • type -> layer in moon.yml
  • --type -> --layer in moon query projects
  • projectType -> projectLayer for MQL
  • $projectType -> $projectLayer for task tokens
  • enforceProjectTypeRelationships -> enforceLayerRelationships in .moon/workspace.yml

🐞 Fixes

• Fixed moon query touched-files --defaultBranch requiring a "true" or "false" explicit value.

⚙️ Internal

• Added telemetry for toolchain usage.
• Added unstable support for bubbling up logs from WASM plugins.
• Updated Rust to v1.88.0.
• Updated proto to v0.51.4 (from 0.50.1).
• Updated dependencies.

🧰 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.

🚀 Updates

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

🐞 Fixes

• Fixed a bun.lock parsing error.

🚀 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.
