### Providers

#### New

* **Node & Python:** Playwright browser installation is now opt-in, preventing unexpected image-size increases. Set `RAILPACK_NODE_PLAYWRIGHT_INSTALL=1` or `RAILPACK_PYTHON_PLAYWRIGHT_INSTALL=1` when Playwright is a production dependency; see the [Node](https://railpack.com/languages/node/#playwright) and [Python](https://railpack.com/languages/python/#playwright) documentation. by @iloveitaly in [#653](https://github.com/railwayapp/railpack/pull/653)

### CLI

#### New

## v0.34.0
July 27, 2026 · [GitHub release](https://github.com/railwayapp/railpack/releases/tag/v0.34.0)

### Providers

#### New

* **Node.js:** npm projects now use `npm install` by default, preventing builds from failing when `package-lock.json` is missing or out of sync. Set `RAILPACK_NODE_NPM_INSTALL="npm ci"` to opt into deterministic installs; Railpack also suggests committing missing npm and pnpm lockfiles, as described in the [dependency recommendations](https://railpack.com/architecture/recommendations). by @iloveitaly in [#643](https://github.com/railwayapp/railpack/pull/643)

### CLI

#### New

### Providers

#### New

* **SvelteKit:** Projects using `@sveltejs/adapter-auto` now automatically produce and run a Node server without manual adapter configuration. Keep `@sveltejs/adapter-auto` in your dependencies, and Railpack will select `adapter-node` during the build and start it with `node build`. by @iloveitaly in [#641](https://github.com/railwayapp/railpack/pull/641)

#### Fixed

* **React Router:** [React Router SPA projects](https://railpack.com/languages/node#static-sites) with `ssr: false` are now correctly detected and served as static sites, even when the default `react-router-serve ./build/server/index.js` start script is present. by @iloveitaly in [#604](https://github.com/railwayapp/railpack/pull/604)

### CLI

#### New

* **Apt Packages:** Custom Apt package lists can now use the `...` spread operator to retain packages generated by Railpack. Follow the [package installation guide](https://railpack.com/guides/installing-packages#apt) and configure `"buildAptPackages": ["...", "build-essential"]` or `"deploy": { "aptPackages": ["...", "ffmpeg"] }`; omit `...` when you intentionally want to replace the generated list. by @iloveitaly in [#645](https://github.com/railwayapp/railpack/pull/645)

#### Fixed

* **Mise:** Railpack now uses musl-compatible mise binaries on Linux, fixing execution on Alpine and other musl-based hosts. by @iloveitaly in [#642](https://github.com/railwayapp/railpack/pull/642)

**Full Changelog**: [v0.32.0...v0.33.0](https://github.com/railwayapp/railpack/compare/v0.32.0...v0.33.0)

## v0.32.0
July 22, 2026 · [GitHub release](https://github.com/railwayapp/railpack/releases/tag/v0.32.0)

### Providers

#### New

* **Node:** Railpack now supports [Next.js applications in Nx workspaces](https://railpack.com/languages/node#nx), including projects that use inferred tasks instead of root build and start scripts. Single-app workspaces are selected automatically; for multi-app workspaces, select an app with `RAILPACK_NX_APP=web railpack build .`. by @iloveitaly in [#606](https://github.com/railwayapp/railpack/pull/606)

#### Fixed

* **Node:** Railpack now displays a build-plan warning when no package manager is detected and npm is selected by default. by @iloveitaly in [#638](https://github.com/railwayapp/railpack/pull/638)

### CLI

#### New

* **Mise:** Updated mise version from v2026.7.7 to [v2026.7.11](https://github.com/jdx/mise/releases/tag/v2026.7.11).
* **Build Cache:** The [build command](https://railpack.com/reference/cli#build) now supports `--no-cache` for rebuilding without cached layers while preserving package-manager cache mounts. Run `railpack build --no-cache .` to perform a fresh build. by @iloveitaly in [#516](https://github.com/railwayapp/railpack/pull/516)
* **Build Output:** Build progress and completion output is now easier to scan, with a distinct start header and a formatted summary containing the build duration and next command. by @iloveitaly in [#640](https://github.com/railwayapp/railpack/pull/640)
* **Runtime Images:** Runtime images now expose [`RAILPACK_VERSION`](https://railpack.com/architecture/secrets#environment-variables), allowing applications and diagnostics to identify the Railpack version that produced the image. Access it through the `RAILPACK_VERSION` environment variable inside the running container. by @iloveitaly in [#633](https://github.com/railwayapp/railpack/pull/633)

**Full Changelog**: [v0.31.2...v0.32.0](https://github.com/railwayapp/railpack/compare/v0.31.2...v0.32.0)

### Providers

#### Fixed

* **PHP:** PHP applications using a single Mise-managed runtime package now include it in the deploy image. by @jordyvandomselaar in [#635](https://github.com/railwayapp/railpack/pull/635)

### CLI

#### New

* **Mise:** Updated mise version from v2026.7.6 to [v2026.7.7](https://github.com/jdx/mise/releases/tag/v2026.7.7).

**Full Changelog**: [v0.31.1...v0.31.2](https://github.com/railwayapp/railpack/compare/v0.31.1...v0.31.2)

## v0.31.1
July 15, 2026 · [GitHub release](https://github.com/railwayapp/railpack/releases/tag/v0.31.1)

### Providers

#### Fixed

### CLI

#### New

* **Mise:** Updated mise version from v2026.7.5 to [v2026.7.6](https://github.com/jdx/mise/releases/tag/v2026.7.6).

**Full Changelog**: [v0.31.0...v0.31.1](https://github.com/railwayapp/railpack/compare/v0.31.0...v0.31.1)

## v0.31.0
July 13, 2026 · [GitHub release](https://github.com/railwayapp/railpack/releases/tag/v0.31.0)

### CLI

#### New

* **Build:** The [`build` command](https://railpack.com/reference/cli/#build) now supports BuildKit [cache import and export](https://railpack.com/architecture/caching/#cache-backends) via `--cache-from` and `--cache-to`, using the same syntax as docker buildx. For example: `railpack build --cache-from type=registry,ref=my.registry/cache --cache-to type=registry,ref=my.registry/cache,mode=max .` by @mvanhorn in [#595](https://github.com/railwayapp/railpack/pull/595)
* **Build:** `railpack build` now uses credentials from your Docker CLI config (`$DOCKER_CONFIG`, default `~/.docker/config.json`) so BuildKit can pull from and push to private registries. Log in with `docker login` first if needed. by @iloveitaly in [#623](https://github.com/railwayapp/railpack/pull/623)
* **Mise:** Updated mise version from v2026.7.2 to [v2026.7.5](https://github.com/jdx/mise/releases/tag/v2026.7.5).

**Full Changelog**: [v0.30.1...v0.31.0](https://github.com/railwayapp/railpack/compare/v0.30.1...v0.31.0)

**Full Changelog**: [v0.30.0...v0.30.1](https://github.com/railwayapp/railpack/compare/v0.30.0...v0.30.1)

## v0.30.0
June 22, 2026 · [GitHub release](https://github.com/railwayapp/railpack/releases/tag/v0.30.0)

### Providers

#### New

* **Deno:** Railpack now reads Deno versions from `.deno-version` files using mise idiomatic version file support. Add a `.deno-version` file to your project root (for example, `2.2.2`) to pin the Deno runtime for your deployment — see [version detection](https://railpack.com/languages/deno#versions) for the full precedence order. by @iloveitaly in [#608](https://github.com/railwayapp/railpack/pull/608)

#### Fixed

* **Python, Ruby, Deno:** `RAILPACK_PYTHON_VERSION`, `RAILPACK_RUBY_VERSION`, and `RAILPACK_DENO_VERSION` environment variables now correctly override local version files and mise configuration during builds, matching the documented precedence order. Set these in your deployment environment when you need to pin a runtime version independently of repository config. by @Vunas in [#610](https://github.com/railwayapp/railpack/pull/610)

### CLI

#### New

* **Mise:** Updated mise version from v2026.6.11 to [v2026.6.12](https://github.com/jdx/mise/releases/tag/v2026.6.12).

**Full Changelog**: [v0.29.0...v0.30.0](https://github.com/railwayapp/railpack/compare/v0.29.0...v0.30.0)

## v0.29.0
June 18, 2026 · [GitHub release](https://github.com/railwayapp/railpack/releases/tag/v0.29.0)

### Providers

#### New

* **Node:** Railpack now detects and deploys Next.js apps configured for static export as SPAs, serving the built site with Caddy. Set `output: 'export'` in your `next.config.ts` (or `.js`/`.mjs`) and Railpack will build and serve the static output from `out` (or your configured `distDir`). See the [Node.js SPA documentation](https://railpack.com/languages/node#spa-mode) for details. by @iloveitaly in [#602](https://github.com/railwayapp/railpack/pull/602)

* **Node:** Node SPA deployments now honor the `index_fallback` key in a `Staticfile` at your project root. SPA routing is unchanged by default, but you can set `index_fallback: false` to disable `index.html` fallback on unknown routes—useful for multi-page static sites that need custom 404 pages. See the [Node.js SPA documentation](https://railpack.com/languages/node#spa-mode) for details. by @iloveitaly in [#582](https://github.com/railwayapp/railpack/pull/582)

* **Node:** Bun-only apps with no dependencies no longer install Node.js in the final image when it isn't needed. by @iloveitaly in [#601](https://github.com/railwayapp/railpack/pull/601)

#### Fixed

* **Node:** Expo projects using the default `expo start` command are no longer incorrectly treated as having a custom start command, so SPA detection works as expected. by @iloveitaly in [#582](https://github.com/railwayapp/railpack/pull/582)

* **Node:** `RAILPACK_NODE_VERSION` now correctly takes precedence over `engines.node` in `package.json`, matching the documented version resolution order. by @iloveitaly in [#601](https://github.com/railwayapp/railpack/pull/601)

**Full Changelog**: [v0.28.0...v0.29.0](https://github.com/railwayapp/railpack/compare/v0.28.0...v0.29.0)

## v0.28.0
June 17, 2026 · [GitHub release](https://github.com/railwayapp/railpack/releases/tag/v0.28.0)

### Providers

#### New

* **Expo Web:** Railpack now detects [Expo Web](https://railpack.com/languages/node/) projects configured for static export as SPAs and serves the built output from `dist` with the static file server. Configure `expo.web.output` to `static` or `single` in `app.json`, ensure `expo` and `react-native-web` are in your dependencies, and add a `build` script such as `expo export --platform web` to your `package.json`. by @iloveitaly in [#585](https://github.com/railwayapp/railpack/pull/585)

#### Fixed

* **Node:** Increased the default npm fetch retry count to 5 (`NPM_CONFIG_FETCH_RETRIES=5`) to improve build reliability against transient registry network errors during dependency installation. by @iloveitaly in [#598](https://github.com/railwayapp/railpack/pull/598)

### CLI

#### New

* **Mise:** Updated mise version from v2026.6.10 to [v2026.6.11](https://github.com/jdx/mise/releases/tag/v2026.6.11).

## v0.27.0
June 9, 2026 · [GitHub release](https://github.com/railwayapp/railpack/releases/tag/v0.27.0)

### Providers

#### Fixed

* **Elixir:** Elixir 1.20 now maps to Erlang 29, so projects on Elixir 1.20 build with the correct OTP version. by @iloveitaly in [#583](https://github.com/railwayapp/railpack/pull/583)

### CLI

#### New

* **Mise:** Updated mise version from v2026.6.0 to [v2026.6.1](https://github.com/jdx/mise/releases/tag/v2026.6.1).

### Runtime

* **Locale:** Builder and runtime images now include the `en_US.UTF-8` locale, fixing warnings and breakage for apps that depend on locale-aware behavior (such as Python or Ruby). Railpack does not set `LANG` or `LC_ALL` by default — enable UTF-8 by adding them to [`deploy.variables`](https://railpack.com/config/file) in your `railpack.json` (for example, `"LANG": "en_US.UTF-8"`). by @iloveitaly in [#576](https://github.com/railwayapp/railpack/pull/576)
* **Timezone:** Builder and runtime images now include `tzdata` by default, so named timezones work out of the box when you set `TZ` or use libraries that read the zoneinfo database. by @iloveitaly in [#580](https://github.com/railwayapp/railpack/pull/580)

**Full Changelog**: [v0.26.1...v0.27.0](https://github.com/railwayapp/railpack/compare/v0.26.1...v0.27.0)

## v0.26.1
June 4, 2026 · [GitHub release](https://github.com/railwayapp/railpack/releases/tag/v0.26.1)

### Providers

#### Fixed

* **Node:** pnpm 11+ projects now build correctly by adding `PNPM_HOME/bin` to the `PATH` so the pre-install `node-gyp` step can be found, including when `engines.pnpm` uses x-range notation like `"11.5.x"`. by @iloveitaly in [#581](https://github.com/railwayapp/railpack/pull/581)

### CLI

#### New

* **Mise:** Updated mise version from v2026.5.18 to [v2026.6.0](https://github.com/jdx/mise/releases/tag/v2026.6.0).

**Full Changelog**: [v0.26.0...v0.26.1](https://github.com/railwayapp/railpack/compare/v0.26.0...v0.26.1)

## v0.26.0
June 2, 2026 · [GitHub release](https://github.com/railwayapp/railpack/releases/tag/v0.26.0)

### Providers

#### Fixed

* **Node (pnpm):** Railpack now sets `PNPM_HOME` to `/opt/pnpm` and `PNPM_STORE_DIR` to `/opt/pnpm/store` during every pnpm install so BuildKit caches the store path pnpm actually uses. This fixes missed install cache hits when newer pnpm versions write outside the old hardcoded store location. by @iloveitaly in [#569](https://github.com/railwayapp/railpack/pull/569)

### CLI

#### Fixed

* **Config:** Custom runtime images set via [`deploy.base`](https://railpack.com/config/file) in `railpack.json` are now applied to the generated deploy step. Previously Railpack parsed `deploy.base` but did not use it when building the final image; configured bases are used as the deploy filesystem and as the input for runtime apt package layers when those are enabled. by @radiantjade in [#561](https://github.com/railwayapp/railpack/pull/561)

* **Mise:** Builds no longer fail when `mise.lock` pins a tool version newer than the default [14-day minimum release age](https://railpack.com/config/mise) while your config requests `latest`. Host-side version resolution applies the age filter first, then falls back when a pinned lockfile version would otherwise be excluded. by @iloveitaly in [#575](https://github.com/railwayapp/railpack/pull/575)

**Full Changelog**: [v0.25.0...v0.26.0](https://github.com/railwayapp/railpack/compare/v0.25.0...v0.26.0)

## v0.25.0
June 1, 2026 · [GitHub release](https://github.com/railwayapp/railpack/releases/tag/v0.25.0)

### Providers

#### New

* **Node:** Railpack now detects and builds projects that use `package.json5` manifests (in addition to `package.json`), including workspace and dependency parsing. If both files exist, `package.json` takes precedence. by @iloveitaly in [#566](https://github.com/railwayapp/railpack/pull/566)

* **Node:** Node 25+ apps that use Corepack (for example `packageManager: "pnpm@..."`) now include the mise install and shim directories in the runtime image, so package managers like `pnpm` remain available when your start command runs after the build. by @iloveitaly in [#568](https://github.com/railwayapp/railpack/pull/568)

#### Fixed

* **Node:** `engines.pnpm` in your manifest now takes precedence over pnpm version inferred from `pnpm-lock.yaml`, avoiding ambiguous lockfile version mapping across major pnpm releases. See [package and version resolution](https://railpack.com/architecture/package-resolution/) for how Railpack resolves tool versions. by @iloveitaly in [#566](https://github.com/railwayapp/railpack/pull/566)

### CLI

#### New

* **Config:** The `provider` field in `railpack.json` is now listed in the generated JSON schema (`railpack schema`), with the same values documented in the [config file guide](https://railpack.com/config/file/). Provider names are matched case-insensitively, so lowercase values like `elixir` and `dotnet` work as documented. by @radiantjade in [#558](https://github.com/railwayapp/railpack/pull/558)

* **Mise:** Updated mise version from v2026.5.16 to [v2026.5.18](https://github.com/jdx/mise/releases/tag/v2026.5.18).

**Full Changelog**: [v0.24.0...v0.25.0](https://github.com/railwayapp/railpack/compare/v0.24.0...v0.25.0)

## v0.24.0
May 29, 2026 · [GitHub release](https://github.com/railwayapp/railpack/releases/tag/v0.24.0)

### Providers

#### New

* **Node:** Package manager versions for pnpm, bun, and yarn defined in mise config (`mise.toml`, `.tool-versions`, etc.) now take priority over versions inferred from lockfiles or project metadata. Pin a version in your config—for example `pnpm = "10.4.1"` in `mise.toml`—and Railpack will use it consistently across the build. See [Node.js versions](https://railpack.com/languages/node#versions) and [Mise configuration](https://railpack.com/config/mise). by @iloveitaly in [#564](https://github.com/railwayapp/railpack/pull/564)

#### Fixed

* **Node:** Builds using pnpm 11+ now add `PNPM_HOME/bin` to `PATH`, matching pnpm’s new layout so global tools like `node-gyp` install and run correctly. by @iloveitaly in [#564](https://github.com/railwayapp/railpack/pull/564)

* **Ruby:** Ruby source builds no longer install rdoc, avoiding locale-related compile failures during `mise install`. by @iloveitaly in [#564](https://github.com/railwayapp/railpack/pull/564)

* **Elixir:** Elixir provider environment variables (locale, `MIX_ENV`, `MIX_HOME`, etc.) are now applied to the mise install step so Erlang and Elixir install with the same settings as the rest of the build. by @iloveitaly in [#564](https://github.com/railwayapp/railpack/pull/564)

* **Python:** Projects using Poetry, PDM, or Pipenv via pipx now also install `uv`, which newer mise requires when `pipx.uvx` is enabled. by @iloveitaly in [#564](https://github.com/railwayapp/railpack/pull/564)

### CLI

#### New

* **Mise:** Updated mise version from v2026.3.17 to [v2026.5.16](https://github.com/jdx/mise/releases/tag/v2026.5.16).

#### Fixed

* **Mise:** Generated `/etc/mise/config.toml` now sets `minimum_release_age` instead of the renamed `install_before` setting, matching current mise behavior. Override it in your own [mise configuration](https://railpack.com/config/mise) if needed. by @iloveitaly in [#564](https://github.com/railwayapp/railpack/pull/564)

**Full Changelog**: [v0.23.0...v0.24.0](https://github.com/railwayapp/railpack/compare/v0.23.0...v0.24.0)

* **Staticfile:** Added a [configurable index fallback](https://railpack.com/languages/staticfile) to the Staticfile provider, allowing users to toggle SPA-style routing for their applications. by @iloveitaly in [#534](https://github.com/railwayapp/railpack/pull/534)
  To enable SPA routing, add `index_fallback: true` to your `Staticfile` configuration to have non-existent paths served by `index.html`.

### CLI

#### New

* **Mise:** Updated mise version from v2026.3.15 to [v2026.3.17](https://github.com/jdx/mise/releases/tag/v2026.3.17). in [#539](https://github.com/railwayapp/railpack/pull/539)
* **Mise:** Introduced a [new installation policy](https://railpack.com/config/mise) that defaults to tool versions released at least 14 days ago to avoid broken or incomplete tool versions. by @iloveitaly in [#540](https://github.com/railwayapp/railpack/pull/540)
  This setting improves stability for runtime environments like Python and Ruby by allowing upstream releases time to stabilize before they are used in production builds.
* **Verbose Mode:** Added support for the `RAILPACK_VERBOSE` environment variable to enable [verbose logging](https://railpack.com/config/environment-variables) and improved debug logs for mise execution. by @iloveitaly in [#536](https://github.com/railwayapp/railpack/pull/536)
  Set `RAILPACK_VERBOSE=1` to enable detailed debug output, including the full command string and captured output from mise during execution.

#### Fixed

* **Configuration:** Improved root directory detection by trimming whitespace from environment variables and configuration values. by @iloveitaly in [#534](https://github.com/railwayapp/railpack/pull/534)

### CLI

#### New

* **Configuration:** Railpack now uses a global `mise.toml` to store default tool configurations instead of environment variables, allowing users to naturally override defaults via their project's local `mise.toml` file. This change makes it easier to customize tool versions and settings without needing to manage complex environment variables. For example, you can now add a `[settings]` section to your project's `mise.toml` to specify exact settings that Railpack should use. by @iloveitaly in [#504](https://github.com/railwayapp/railpack/pull/504)
* **Mise:** Updated mise version from v2026.3.10 to [v2026.3.12](https://github.com/jdx/mise/releases/tag/2026.3.12).
