ADL Release 2.1.1

Release Notes


This document provides release information for The Assertion Definition Language Translation System (ADL)

1  Release Overview

ADL 2.1.1 is a maintenance release. It provides a single bug fix, and is identical in other respects to the previous release, version 2.1.

1.1 Changes since the last release

The single bug fix for this release involves the assignment of default values to float types in ADLJava. Previously, ADL would auto-generate a float type with the default value of '0.0' which is interpreted by java as being a double value. This version ADL sets the default value to '0.0f' which explicitly identifies it as a float value and prevents a cast error during compilation.

There are no other functional changes.
