Mise Updated mise version from v2026.2.14 to v2026.3.9.
Node.js: Node.js projects using Bun now support bunfig.toml during the installation step. This ensures custom registries and install behaviors are correctly applied when running bun install. by @iloveitaly in https://github.com/railwayapp/railpack/pull/477
Ruby: Upgraded to jemalloc2 for Ruby projects to resolve errors on ARM architecture and improve memory performance. This is enabled by default. by @iloveitaly in https://github.com/railwayapp/railpack/pull/338
Python: Added documentation and an example for using compiled Python as an escape hatch when pre-built binaries are not available for specific versions. This allows developers to use specific Python builds by opting into compilation during the build process. by @iloveitaly in https://github.com/railwayapp/railpack/pull/503

Ruby: Default Ruby versions are now pinned to the minor version instead of a specific patch to allow for automatic security updates and better compatibility with pre-built binaries. by @iloveitaly in https://github.com/railwayapp/railpack/pull/488
Staticfile: Switched to a binary installer for Caddy to achieve smaller image sizes for static site deployments. by @iloveitaly in https://github.com/railwayapp/railpack/pull/478

CLI: The CLI now issues a warning if no start command is detected during the build process, providing clearer feedback on potentially missing configuration. by @iloveitaly in https://github.com/railwayapp/railpack/pull/490
