Release Notes

🚀 Updates

• Cache
  • Added a new experiment that stores task outputs in a local content-addressable storage (CAS)
    cache, sharing the same format used by the remote cache. Enables deduplicated storage across
    tasks and a unified cache shape locally and remotely.
    • Enable with the experiments.casOutputsCache setting in .moon/workspace.*.
  • Added a new top-level cache setting in .moon/workspace.* for tuning the content-addressable
    storage (CAS) cache.
• Daemon
  • When pipeline.autoCleanCache is enabled (by default), the auto-clean will now run in the
    daemon, instead of at the tail-end of the main process.
  • When utilizing webhooks, the requests will now be made from the daemon, instead of the main
    process.
• Git
  • Added SHA256 support for commit hashes. This is in preparation for Git's transition to SHA256 as
    the default hash algorithm.
• Hash
  • Added a new experiment that replaces the VCS/Git based file hashing mechanism with a custom
    native implementation that runs within our task pool. This can improve performance by 10-50%.
    • Enable with the experiments.nativeFileHashing setting in .moon/workspace.*.
• MCP
  • Added get_template and get_templates tools so AI coding assistants can discover templates
    and inspect their variable schemas before calling generate.
• Tasks
  • Added tags support to tasks through new tags and options.mergeTags settings.
    • Added taskTag field support to MQL.
    • Added --tags option support to moon query tasks.
    • Updated targets to support the # tag syntax in the task scope, allowing you to reference
      tasks by their tags. For example: app:#quality.
  • Added a cacheStrategy field to task dependencies that controls how a dependency's changes
    invalidate the current task's cache. Supports hash, ignored, and outputs — the latter
    mixes in the dependency's output files instead of its hash, so build tasks are only invalidated
    when upstream outputs change, not when upstream inputs change.
    • Behavior change: when cacheStrategy is omitted, the default is now hash if the
      dependency declares outputs and ignored if it doesn't, instead of always hash. Tasks that
      depend on output-less tasks (e.g. lint, test) will see fewer cache invalidations. Set
      cacheStrategy: 'hash' explicitly to restore the previous behavior for a given dependency.
• Performance
  • Reduced task target memory footprint by 50-100%.

🧰 Toolchains

• JavaScript
  • Added support for Deno v2.8.
    • Will use deno ci for installs in CI when deno.lock exists and the configured Deno version
      is >= v2.8.
    • Will pass --prod to deno install for production installs when the configured Deno version
      is >= v2.8.
    • Will resolve catalog: references in package.json files using catalogs declared in a root
      deno.json.
• Python
  • Added unstable support for uv pip.
    • Can be configured using unstable_python.packageManager: 'uv-pip' in .moon/toolchains.*.
    • Will inherit install arguments from unstable_pip.installArgs.
    • Will inherit sync arguments from unstable_uv.syncArgs.
    • Will inherit venv arguments from unstable_uv.venvArgs.

🐞 Fixes

• Fixed a glob regression where unbounded walks could be up to 10x slower.
