What it does

Tax rules and deadlines change constantly — across the IRS, all 50 states, and FEMA. DueDateHQ watches all of them 24/7, catches every change, and shows you exactly which clients are affected — then applies the new date to their deadlines in one click.

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).
