This week's developer digest covers Grok 4.5, xAI's new model optimized for coding and agentic tasks with 4.2x token efficiency at competitive pricing. TypeScript 7.0 lands as a native Go port delivering 8-12x faster builds and improved editor responsiveness. Bun is being rewritten from Zig to Rust for memory safety, with Claude Fable 5 helping port 535k lines of code. Other highlights include ECMAScript 2026's 8 new features, a clarification on PyPI Trusted Publishing as authentication-only (not a safety signal), Vercel acquiring Better Auth (4.7M+ weekly downloads), npm v12's opt-in security model for install-time scripts, pnpm 11.10, and PL/Ruby 2.5.0 for writing PostgreSQL functions in Ruby.
