release notes

This release smooths over follow-ups to v2026.6.2's built-in `minimum_release_age` cutoff, introduces opt-in platform-aware config environments, and tightens lockfile and Windows behavior for tasks and installs.
Added

(config) New auto_env early-init setting (MISE_AUTO_ENV or .miserc.toml) that automatically activates platform-derived config environments — unix, {os} (linux / macos / windows), and {os}-{arch} (e.g. windows-x64, macos-arm64) — so files like mise.windows.toml, mise/config.macos-arm64.toml, and matching mise.<env>.lock lockfiles load automatically. Precedence is unix < {os} < {os}-{arch} < explicit MISE_ENV, and auto envs are deliberately not propagated through MISE_ENV or {{ mise_env }}. Off by default in this release; a transitional warning ships in 2026.12.0 and the default flips on in 2027.6.0 (#10316 by @jdx).
(github) mise token github --oauth --refresh (and the hidden mise github token alias) forces a fresh OAuth token mint even when the cached token is still time-valid. The refresh-token grant is tried first with no user interaction, falling back to a new device-code flow. Useful when you authorize the app first and install it on a repo afterwards and the cached token still has the pre-installation permissions (#10317 by @jdx).
(backend) version_expr can now post-process version_regex results as a pipeline — when both are set, regex output is exposed as a versions variable to expr. This fixes oc and openshift-install latest resolution (now 4.22.0 instead of 4.9.9) by sorting the lexicographic HTML listing from mirror.openshift.com via version_expr = 'sortVersions(versions)' (#10302 by @konono).
(deps) First-class Deno support in mise deps — automatic detection plus list, install, add, and remove (#10291 by @felipecrs).
(registry) Added imagemagick (aqua:ImageMagick/ImageMagick) (#10118 by @thernstig) and vscode-cli (aqua:microsoft/vscode/code) (#10314 by @felipecrs).

Fixed

(config) The built-in 24h default minimum_release_age introduced in v2026.6.2 no longer disables installed-version fast paths, fixing a regression where shell startup grew from ~2.5s to ~65s because every mise which / mise hook-env invocation fetched remote version lists. Cutoff resolution now tracks provenance (Default / Provided / Explicit): the default only gates remote picks at install time, while explicit CLI / setting / per-tool cutoffs keep their date-aware semantics (#10315 by @jdx).
(backend) minimum_release_age = "0s" is now correctly treated as disabling the cutoff. Backends can also expose fast-path latest release metadata (with created_at), so the canonical latest can pass an age check even when cached remote version lists are stale (#10310 by @jdx).
(python) Core Python remote versions now carry release timestamps — python-build-standalone dates for precompiled listings and python-build definition commit timestamps for source-build listings — so minimum_release_age actually filters them (#10311 by @jdx).
(lock) Tools resolved from idiomatic version files (.node-version, .python-version, …) are now written to the project mise.lock instead of a phantom sibling lockfile, so mise install --locked no longer rejects them as missing (#10309 by @jdx). When multiple base configs share a project root, lockfile selection is now deterministic and picks the highest-precedence config — e.g. colocated mise.toml and .mise/config.toml consistently target .mise/mise.lock (#10319 by @jdx).
(task) Tasks loaded via task_config.includes now receive the collected task_templates map, so a task that only has extends = "template:..." actually inherits its run entries instead of silently exiting successfully (#10312 by @jdx).
(task) On Windows, inline tasks and [hooks] commands routed through cmd /c preserve inner double quotes. Previously, the std argv serializer produced \"-escaped strings that cmd.exe passed through literally, so e.g. uv run --no-project python -c "import pathlib; print(pathlib.Path.home())" failed with SyntaxError: unterminated string literal. Commands are now built verbatim via cmd /s /c "...", with forwarded args still MSVCRT-quoted inside (#10301 by @JamBalaya56562).
File renames during install now retry up to 5 times on Windows for transient ERROR_ACCESS_DENIED (5) and ERROR_SHARING_VIOLATION (32) errors (typically Windows Defender holding extracted files), with exponential backoff from 50ms to 800ms (#10300 by @jhult).
(completions) Require usage 3.5 in the generated usage spec to pick up zsh colon completion fixes; the zsh completion script now consumes three tab-separated fields and uses compadd (#10313 by @jdx).
(registry) podman now points at its new GitHub organization after the upstream rename on 2026-06-01 (#10288 by @TyceHerrman).
