Railway

Recently shipped Railpack v0.34.0 and v0.35.0, plus CLI v5.29.x-v5.30.x with MCP proxy, DNS logs, and auth stability.

Railpack changed npm defaults and made Playwright opt-in. npm projects now use npm install by default, avoiding build failures when package-lock.json is missing; set RAILPACK_NODE_NPM_INSTALL="npm ci" for deterministic installs. Playwright browser installation for Node and Python is now opt-in via RAILPACK_NODE_PLAYWRIGHT_INSTALL=1 or RAILPACK_PYTHON_PLAYWRIGHT_INSTALL=1.

CLI gained MCP proxy, DNS logs, and auth resilience. railway mcp proxies the remote MCP server over stdio using the CLI login. DNS logs appear in railway logs. OAuth handling improved: dead credentials are cleared on invalid_grant, and transient refreshes retry to prevent MCP token freezing.

Railpack build cache and private registry support matured. railpack build accepts --cache-from and --cache-to with BuildKit-compatible syntax, pulls credentials from Docker CLI config, and supports --no-cache for fresh builds while preserving package-manager caches. Apt package lists can use the ... spread operator.

Python Poetry installs via mise instead of pipx, and mise updated across releases to v2026.7.15.
