What it does

Prompt management for developers. Every edit is a commit, so you can diff any two versions, leave review notes, and roll back in one click. Define typed variables once and reuse prompts everywhere. Promote drafts from staging to production, score them against test cases, and run live A/B experiments. Then fetch the right version for each environment with one call over an edge-cached, fully typed SDK or REST API. Change a prompt and it goes live in seconds, with a clean audit trail behind it.

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!
