This release adds an opt-in bootstrap mode for projects that use mise bootstrap, and makes the action work on runner images that ship wget but not curl.
Three new inputs let the action drive mise bootstrap instead of mise install:
- uses:jdx/mise-action@v4with:bootstrap:truebootstrap_skip:"tools,task"# comma-separated parts to skipbootstrap_args:"--yes"# extra args forwarded to mise bootstrap
When bootstrap: true, the action runs mise bootstrap under the existing install gate and sets MISE_EXPERIMENTAL=1 automatically.
If a repo mise lock file is present, it runs mise --locked bootstrap, matching the auto-lock behavior introduced for mise install in v4.1.0.
install_args cannot be combined with bootstrap: true — the action fails fast and tells you to use bootstrap_skip / bootstrap_args instead, because full bootstrap doesn't support partial tool install args.
A new {{bootstrap_hash}} template variable is included in the default cache key (and available in custom cache_key templates) so bootstrap and non-bootstrap configurations don't share caches.
bootstrap_skip relies on mise bootstrap --skip from jdx/mise#10497, so make sure you're on a recent mise version if you use it.
Fixed
Fall back to wget when curl is unavailable (#521) by @risu729 — The action used to hard-code curl for fetching the mise binary, tar/zip archives, and the latest VERSION lookup, which broke on minimal runner images that only ship wget. It now prefers curl and transparently falls back to wget, preserving the streaming download | tar fast path for .tar.gz and .tar.zst installs on Linux/macOS. Proxy support is unchanged — both tools honor HTTP_PROXY/HTTPS_PROXY. Addresses jdx/mise#10488.

### [`v4.2.0`](https://github.com/jdx/mise-action/releases/tag/v4.2.0): : Bootstrap mode & wget fallback
[Compare Source](https://github.com/jdx/mise-action/compare/v4.1.0...v4.2.0)
This release adds an opt-in **bootstrap mode** for projects that use `mise bootstrap`, and makes the action work on runner images that ship `wget` but not `curl`.
#### Added
##### Bootstrap mode ([#​522](https://github.com/jdx/mise-action/pull/522)) by [@​jdx](https://github.com/jdx)
Three new inputs let the action drive `mise bootstrap` instead of `mise install`:
```yaml
- uses: jdx/mise-action@v4
with:
bootstrap: true
bootstrap_skip: "tools,task" # comma-separated parts to skip
bootstrap_args: "--yes" # extra args forwarded to mise bootstrap
```
- When `bootstrap: true`, the action runs `mise bootstrap` under the existing `install` gate and sets `MISE_EXPERIMENTAL=1` automatically.
- If a repo mise lock file is present, it runs `mise --locked bootstrap`, matching the auto-lock behavior introduced for `mise install` in v4.1.0.
- `install_args` cannot be combined with `bootstrap: true` — the action fails fast and tells you to use `bootstrap_skip` / `bootstrap_args` instead, because full bootstrap doesn't support partial tool install args.
- A new `{{bootstrap_hash}}` template variable is included in the default cache key (and available in custom `cache_key` templates) so bootstrap and non-bootstrap configurations don't share caches.
`bootstrap_skip` relies on `mise bootstrap --skip` from [jdx/mise#10497](https://github.com/jdx/mise/pull/10497), so make sure you're on a recent mise version if you use it.
