v2026.7.3: System dependency checks and cask lifecycle hooks

This release brings smarter builds for source-compiling tools, better Homebrew cask support, and a fix for lockfile entries losing their platform data during upgrades.

Added

• vfox: plugin-declared system dependencies. Source-compiling plugins (php, mysql, erlang, ...) often need build tools and libraries that previously showed up only as a failed ./configure twenty minutes into a build. vfox plugins can now declare these prerequisites in metadata.lua, and mise checks them before installing (#10848 by @jdx):

  PLUGIN.systemDependencies = {
      { bin = "bison", version = ">=3.0", packages = { brew = "bison", apt = "bison" } },
      { pkgconfig = "libxml-2.0", packages = { brew = "libxml2", apt = "libxml2-dev" } },
      { sharedlib = "libaio.so.1", packages = { apt = "libaio1" } },
  }

  Detection is the source of truth: a satisfied check passes regardless of how the capability was installed (Homebrew, apt, nix, from source), and the per-manager packages map is only used to offer installing the missing subset. A new system_deps setting controls behavior (prompt default, auto, warn, ignore); the check never fails an install. Missing deps also show up in mise doctor and mise bootstrap status. Declarations are inert on older mise versions and on upstream vfox.

• brew: cask lifecycle hooks. Homebrew cask installs now run supported preflight and postflight hooks via a mise-owned, sha256-verified Ruby shim (no brew delegation), which fixes wrapper-style casks like GIMP. Unsupported hook DSL fails with an explicit error (#10837 by @jdx).

• cli: terminal width override. In some CI environments width detection returns a bogus value and mise's table/list output (mise ls, mise registry, mise settings) renders oddly with no way to fix it. You can now override the detected width (#10862 by @JamBalaya56562):

  MISE_TERM_WIDTH=120 mise ls

  MISE_TERM_WIDTH takes precedence, with COLUMNS as a fallback. An explicit override is honored exactly (no 80-column floor); behavior is unchanged when neither is set.

Fixed

• upgrade: mise upgrade --bump can rewrite more lockfile entries than the tools it actually installs. Those rewritten entries were previously reduced to bare version/backend records, losing their cross-platform checksums and URLs. mise now re-locks stale entries that are missing platform metadata, so tools like ruff, biome, and typos keep their full lock data (#10752 by @zeitlinger).
• brew: casks whose binary is created by a pkg installer at an absolute path (e.g. karabiner-elements) now install correctly, staged through the caskroom as symlinks (#10841 by @jdx).
• vfox: traditional vfox plugin downloads now go into mise's per-tool download directory so they are cleaned up after install (#10840 by @risu729).
• brew: included the cask shim in the published crate, fixing a cargo publish verification failure (#10863 by @jdx).

Changed

• registry: switched a large batch of tools to the vfox backend: scala, groovy, mongodb, emsdk, teleport-community, teleport-ent, tinytex, mysql, elasticsearch, v, spring-boot, php, clojure, oci, jib, graalvm, gcc-arm-none-eabi, and tiny.

Documentation

• De-slopified the landing page copy and visuals (#10836 by @jdx).
