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 for the full precedence order. by @iloveitaly in #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

CLI

New

• Mise: Updated mise version from v2026.6.11 to v2026.6.12.

Internal improvements to Node SPA framework detection, Bun version file handling, testing, and dependency updates by @iloveitaly.
