Heroku

Heroku CLI v11 is now available, marking the most significant architectural overhaul in years. The release completes a full migration to ECMAScript Modules (ESM) and oclif v4, delivering faster command execution through improved tree-shaking and manifest caching. The CLI now ships with Node.js 22 (while maintaining Node.js 20 compatibility), introduces a semantic color system with theme support and NO_COLOR accessibility option, and adds new commands including heroku search for command discovery, heroku repl, and unified data:maintenance:* commands. Breaking changes include updated output formatting, deprecation of legacy pg:maintenance and redis:maintenance commands, and the AI plugin becoming an optional install. The build system also migrated from Yarn to npm, dropping the monorepo structure.

Modern architecture built for performance and usability

<p>Nice upgrade. Moving to ESM and oclif v4 should make the CLI faster and cleaner, and the new search/repl commands look really useful for day-to-day workflows.</p>
