release notes

This release adds OS/architecture compound filtering for tool configuration, lets task confirmation prompts default to "no" for destructive actions, and upgrades npm supply chain protection to use the recommended `--min-release-age` flag. It also fixes several bugs including a panic on empty config filename overrides and circular shim symlinks.
Highlights

Tool os field now supports os/arch compound entries like "macos/arm64" or "linux/x64", letting you restrict tools to specific platform and architecture combinations.
Task confirm can now default to "no", so destructive tasks require the user to explicitly opt in rather than just pressing Enter.
npm supply chain protection now uses the purpose-built --min-release-age flag on npm 11.10.0+, aligning with npm's recommended approach.

Added


OS/architecture compound syntax in tool filtering -- The os field on tool entries now accepts os/arch entries (e.g. os = ["linux", "macos/arm64"]). When an entry contains /, both the OS and architecture must match. Plain OS entries continue to match any architecture. OS aliases (darwin to macos) and arch aliases (aarch64 to arm64, x86_64/amd64 to x64) are normalized automatically. #9088 by @RobertDeRose
[tools]
# Install on all Linux machines and Apple Silicon Macs, but skip Intel Macs
hk = { version = "latest", os = ["linux", "macos/arm64"] }


Task confirmation default -- The confirm field on tasks now accepts a map with message and default keys, allowing you to set whether the prompt defaults to "yes" or "no". This is useful for destructive tasks where you want the user to explicitly confirm. The existing string syntax continues to work and defaults to "yes" for backwards compatibility. #9089 by @roele
[tasks.release]
confirm = { message = "Are you sure you want to cut a release?", default = "no" }
run = "scripts/release.sh"


npm --min-release-age for supply chain protection -- When install_before is configured, mise now uses npm's --min-release-age=<days> flag for npm 11.10.0+, which is the flag npm recommends for supply chain protection. Older npm versions continue to use --before. Sub-day windows also fall back to --before since --min-release-age is day-granular. #9072 by @webkaz


New registry entries -- Added openfga (#9084 by @mnm364), copilot (#9082 by @risu729), and trzsz-go (#9083 by @ZeroAurora).


Fixed


Panic on empty MISE_OVERRIDE_CONFIG_FILENAMES -- Setting MISE_OVERRIDE_CONFIG_FILENAMES="" (e.g. to clear it for a child process) caused a panic because the empty string was injected as a config path, which resolved to the filesystem root and had no parent directory. Empty segments from empty strings, leading/trailing colons, and consecutive colons are now filtered out. #9076 by @baby-joel


Circular shim symlinks when shims are on PATH -- When mise activate --shims put the shims directory on PATH and a mise shim existed (e.g. from having core:rust in the toolset after a cargo install), reshim would create shims pointing to the mise shim instead of the real binary, including a circular mise to mise symlink that broke all shims. doctor would also falsely report all shims as "missing". Both now use which_no_shims to resolve the real mise binary. #9071 by @kevinswiber


__MISE_EXE not exported in bash activate -- The __MISE_EXE variable was not exported in the bash activation script, so child shells couldn't access it and the mise function failed. Additionally, when ARGV0 was a bare name (e.g. mise) instead of an absolute path, PATH changes could break execution. The variable is now properly exported and bare names are resolved via which. #9081 by @fru1tworld


Aliased installs sharing a backend were deduplicated -- When multiple tool aliases (e.g. iii and iii-console) resolved to the same backend and version (e.g. github:iii-hq/iii@latest), the install scheduler collapsed them into a single job and skipped the second install. The dependency graph now keys on the configured tool name plus version, so alias-specific options like asset_pattern and bin_path are preserved. #9093 by @jdx
