Overview

This page has information regarding the current and historical Swift/T releases.

Swift/T consists of multiple components which have their own version numbers. The release numbers are formatted as major.minor.bugfix.

Swift/T will make feature releases on a monthly basis, which increment the minor version number.

Installation: After downloading Swift/T, see the installation instructions.
