Appendix C  Revision History

Different versions of Reactis are labeled as shown in Figure C.1 and described below.

Figure C.1: Version labels begin with a “V” and include three parts: a year, a major release number, and a patch release number. The parts are numbers separated by decimal points. By convention, trailing zeros are omitted.

Major Releases.
A new version of Reactis is released at the start of each year and labeled by a “V” followed by the four-digit year, for example V2018. Each label for an intra-year release includes a suffix consisting of a decimal point followed by a major release number; for example V2018.1, V2018.2, etc. will label the releases during 2018 that follow V2018.
Beta Releases.

Reactive Systems sometimes makes beta releases available to customers interested in evaluating the newest features of Reactis. Beta releases do not undergo as much testing as major releases do. By convention, beta releases have odd numbered major release numbers. For example, V2018.1, and V2018.3 denote beta releases.

Patch Releases.
Both stable and beta releases may be patched. The label for a patch release is constructed by extending the label for the major release to be patched with a suffix that includes a second decimal point and a patch release number. For example:
V2018.0.1denotesthe first patch release for V2018
V2017.2.3denotesthe third patch release for V2017.2

C.1  Patches Mailing List Archive

Patches to Reactis are posted to the Reactive Systems website every two to four weeks on average. To view a summary of recent changes, please view the archives of the Reactis Patches mailing list available at:

C.2  V2018 (27 June 2018)

The V2018 release of Reactis includes the bug fixes that were included in release V2017.2.1 plus the new features listed below.

C.2.1  Newly Supported Simulink Features

The following Simulink features are supported in Reactis V2018:

  • MATLAB R2018a.
  • In the Lookup Table block, some restrictions on the combinations of different type settings were relaxed. Specifically, Reactis now supports Lookup Table blocks in which the output type does not match the intermediate type.

C.2.2  Open Scopes from Test Suite Browser

You can now open scopes from within the test suite browser for any signals stored in a test suite (inputs, outputs, test points).

C.2.3  Revamped User-Guided Simulation

The User-Guided Simulation mode of Reactis Simulator has been revamped. The new Next Input Values dialog now lets you either enter a concrete value (as it previously did) or an expression to be evaluated to compute the next value for an input. This offers an easy way to specify a ramp or sine wave for in input signal. Additionally, the stepping buttons are now available in the Next Input Values dialog as well as the main Simulator window. Also, you can now control Configuration Variables (at the start of a test) and observe outputs or test points. Scopes can easily be opened for a subset of signals from the Next Input Values dialog.

C.2.4  Comments for Excluded Coverage Targets

Reactis V2015 introduced the capability to exclude individual coverage targets from being tracked. When you exclude a target, Reactis Tester will not attempt to exercise the target when it generates tests and the target will not be factored into coverage tracking and reporting. V2018 enhances this feature by letting you include a comment along with any excluded target. This comment might include when the target was excluded and by whom, along with some explanation of why it was excluded.

C.2.5  API Improvements

New functions to remove Validator Objectives and to query the values of parameters in Validator Objectives were added.

C.2.6  Reactis for EML Plugin

Added support for ~ operator to ignore one or more return values of a function.

C.3  Previous Major Release Dates

Major releases of Reactis prior to V2018 have occurred on the following dates:
