What it does

The Opencals Storefront API is now public! It's a clean REST API and typed TypeScript SDK for building fully custom booking websites – browse services, check real-time availability (single slots or date ranges for rentals), filter by staff and location, collect Stripe payments, and manage customer accounts. All the hard parts – double-booking, timezones, multi-staff and multi-location logic – are handled server-side.

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!
