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 between major releases. To view a summary of recent changes, please view the archives of the Reactis Patches mailing list available at:

C.2  V2018.2 (20 December 2018)

The V2018.2 release of Reactis includes the bug fixes that were included in patch releases through V2018.0.2 plus the new features listed below.

C.2.1  Newly Supported Simulink Features

The following Simulink features are supported in Reactis V2018.2:

  • MATLAB R2018b.
  • Signals with dimensions greater than 2 in Simulink and Stateflow.
  • “Input port” setting for initial condition in Delay block.
  • Matrices as initial conditions in Delay block.

C.2.2  Version Information in .rsi Files

The .rsi file which stores the input port constraints and model-specific settings for a model now tracks the following version information:

  • A revision number for the .rsi file that is increased automatically every time the .rsi file is modified and saved.
  • The user name under which the last modification was made.
  • The date of the last modification.

This information can be seen by selecting Edit -> General in the Reactis GUI and can be queried using the rsRsiGetParameterValue() function in the API. The revision number is also included in test execution and coverage reports (next to the .rsi file name).

C.2.3  Cumulative Coverage Tracking for Referenced Subsystems and Models

It is now possible to track coverage for referenced subsystems and models cumulatively. To select a system or model for cumulative coverage, navigate to an instance of the system in the hierarchy tree, right-click on the name and select Coverage Tracking -> Cumulative.

Coverage for cumulatively tracked systems is shown in a special section in the hierarchy tree. Interactions such as breakpoints and data observation continue to be handled in the specific instances.

C.2.4  API

The following functions have been added to the Reactis API:

rsRsiSetCumulativeCoverage: Enable/Disable cumulative coverage tracking for a referenced model or library subsystem.
rsRsiIsCumulativeCoverage: Check cumulative coverage tracking status for a referenced model or library subsystem.
rsRsiGetCumulativeCoverage: Query all systems/models for which cumulative coverage tracking is enabled.

C.2.5  Reactis for EML Plugin

  • Support type arguments to zero, one and eye functions.
  • Support scalar expansion in .^ operator.
