This release expands the experimental task output cache with per-run controls, a configurable cache directory, and command-derived cache inputs, and lays the groundwork for monorepo-aware task workspaces starting with Node discovery. It also teaches mise mcp to expose each command's read/write/destructive effect to agents, consolidates dotfiles management under mise bootstrap, and lands a broad batch of fixes across brew, npm, tasks, config rewriting, and OCI pushes.

Highlights

  • The experimental task output cache gains per-run controls (--task-cache / MISE_TASK_CACHE), a configurable task.cache_dir, and cache.command_inputs so cache keys can fold in runtime state like compiler versions.
  • New experimental workspace project graph model with Node monorepo discovery (npm, pnpm, Yarn, Bun) via Aube, the foundation for monorepo-aware affected-project and task inference.
  • mise mcp can now tell agents what a command does: the new list_commands tool returns each command's read/write/destructive effect so agents can reason about safety before running anything.

Added

  • task: per-run cache controls via --task-cache <mode> and MISE_TASK_CACHE, supporting read-write (default), read-only, write-only, off, and local-only. Read-only lets untrusted CI jobs consume existing results without publishing misses, write-only warms the cache without consuming entries, and off gives a clean diagnostic path while preserving normal sources freshness. Honored by mise run and bootstrap/naked task entry points. (#11396 by @jdx)

  • task: experimental task.cache_dir setting and MISE_TASK_CACHE_DIR to place task output artifacts on dedicated volumes or project-specific locations without relocating mise's entire cache. mise cache clear and mise cache prune cover the custom location. (#11399 by @jdx)

  • task: experimental cache.command_inputs so cacheable tasks invalidate on command-derived state (like node --version or a generated config fingerprint) that isn't captured by source files. Each command runs in the task directory with the resolved tool environment, and its text plus stdout/stderr hashes fold into the cache key. (#11381 by @jdx)

    [tasks.build]
run = "..."
sources = ["src/**/*.rs"]
outputs = ["dist/app"]
cache = { enabled = true, command_inputs = ["rustc --version"] }

  • task: experimental workspace project graph model and provider interface, the ecosystem-neutral foundation for Node, Cargo, uv, and Go monorepo discovery, plus Node workspace discovery for npm, pnpm, Yarn, and Bun monorepos powered by Aube's shared manifest parsing and workspace-confined scanning. (#11400, #11418, #11420, #11422, #11424, #11427, #11430, #11445 by @jdx)

  • mcp: new list_commands tool exposing mise's command tree with each command's declared effect (read, write, destructive, or unclassified), help text, and hidden status, so agents can see what a command does before invoking it. An optional include_hidden controls visibility, and unclassified is explicitly treated as unknown rather than safe. (#11389 by @jdx)

  • cargo: cargo.binstall_native graduates from experimental and can now discover conventionally named GitHub release artifacts from a crate's linked repository when package.metadata.binstall is absent, so more precompiled binaries install without crate-specific configuration. It also works under the default locked = true path. (#11433 by @jdx)

  • dotfiles: new mise bootstrap dotfiles unapply (with hidden mise dotfiles unapply compatibility alias) to remove managed symlinks, copies, templates, and edit blocks while preserving unmanaged content. Supports target filters, --dry-run, --yes, and requires --force for modified or ambiguous content. (#11437 by @jdx)

  • bootstrap: dotfiles management is now consolidated under mise bootstrap dotfiles (add, edit, apply, status), which runs pre-dotfiles/post-dotfiles hooks correctly. The top-level mise dotfiles command is hidden and deprecated (warnings in 2027.2.0, removal in 2028.2.0) but still works. (#11436 by @jdx)

  • bootstrap: added bs as a visible shorthand alias for mise bootstrap. (#11439 by @jdx)

  • spm: new install_command option for source installs runs a custom command from the checked-out package, and fails the install when the command exits successfully but installs nothing into bin/ (protecting against scripts that swallow build failures). (#11369 by @Marukome0743)

Fixed

  • backend: a network failure while listing remote versions is now reported as a fetch failure instead of a misleading "no versions found matching date filter". The failure is memoized per process to avoid redundant HTTP retries, cutting duplicate warning spam and install time roughly in half in the failing case. (#11391 by @jdx)
  • config: mise use, mise up --bump, and mise set now preserve trailing inline comments when rewriting mise.toml, matching the existing behavior for comments above a line and for .tool-versions. (#11415 by @JamBalaya56562)
  • oci: chunked mise oci push now accepts 201 Created on the chunk PATCH, fixing large-layer pushes to AWS ECR that previously failed with blob chunk upload failed: 201. (#11376 by @fire-ant)
  • npm: tools resolved from a mise.lock pin are now trusted through aube's low-download popularity gate for the requested package, so reproducing an existing lockfile no longer requires allow_low_downloads. First-time unlocked installs and OSV malicious-package checks are unchanged. (#11384 by @jdx)
  • npm: aube confirmation prompts are now routed through mise's shared prompt path. (#11441 by @jdx)
  • pipx: no longer suggests uv when uvx is disabled for the package. (#11373 by @JamBalaya56562)
  • dotfiles: symlink-each now prunes stale mise-managed symlinks left behind when a source file is deleted (reporting them as drift in mise dotfiles status), collapses emptied directories, and gains exclude glob patterns for directory-walking modes, while leaving unmanaged files and user links untouched. (#11388 by @jdx)
  • brew: maintain linked-keg compatibility records (#11371 by @benjaminwestern), adopt existing cask completion links (#11383 by @jdx), and use the download client for artifacts (#11428 by @jdx).
  • aqua: preserve legacy root binary layouts so tools that expect binaries at the install root keep working. (#11397 by @jdx)
  • shim: missing executables are now attributed to the configured tool that should provide them. (#11398 by @jdx)
  • bootstrap: the generated install script honors MISE_VERSION and MISE_INSTALL_PATH (#11401 by @JamBalaya56562), and mise-managed mas is now detected (#11429 by @jdx).
  • generate: git pre-commit hooks respect quiet flags (#11310), use the current env directive syntax (#11311), and resolve hooks correctly in git worktrees (#11313) — all by @Marukome0743.
  • task: support mixed file task dependencies (#11382 by @jdx), deduplicate equivalent task sources (#11204 by @risu729), support multi-line arrays in file task headers (#11412 by @Marukome0743), allow false to override script headers (#11112 by @risu729), and treat a missing content-hash baseline as stale (#11447 by @JamBalaya56562).
  • link: reject selector-style link requests. (#11218 by @risu729)
  • progress output no longer repaints over interactive confirmation prompts; the shared renderer is now suspended while a prompt owns the terminal. (#11421 by @jdx)
