v1.8.10 is released

New in this release:

  • Added a new mode for the Simulink report generator - XML_WITH_IMAGES
    • If the output file is output.xml, there will now be a folder output.xml_images which contains a series of 1:1 scale png images.
    • Each changed block will have xml attributes left_img and right_img, which will point to the filename of an image which highlights that particular change.
    • Each diagram which contains changes will have xml attributes left_diagram_img and right_diagram_img, which will point to the filename of an image which contains all the changes of that particular subsystem.
    • Normally, the XML report format only contains xml elements for items which have been changed or added. In XML_WITH_IMAGES mode, a subsystem which is itself identical, but contains changed children, will appear in the XML document as a nested element, and will have left_diagram_img and right_diagram_img properties.
  • Simulink subsystems and subcharts can now be opened in a new tab.
    • Open new subsystems in a new tab
  • When moving up a subsystem, the previously displayed subsystem is now highlighted briefly.
    • In the viewer:
      Highlight parent system in viewer
    • In the differ:
      Highlight parent system in differ
  • Added the license-user=LICENSEFILE flag to the installer for advanced batch installation.

Fixed in this release:

  • DiffPlug had problems displaying systems containing blocks whose names started with the # character.
    • This did not affect logical diffing, but it did affect graphical display.
  • Fixed an issue where Simulink files could not be opened if they didn’t have an .slx or .mdl extension.
  • Fixed various Subversion issues.
  • Fixed a segfault that some Ubuntu users were experiencing due to a recent kernel patch.

v1.8.9 is released

New in this release:

  • On linux and mac, the dp command line client can now be symlinked and still perform properly.
    • ln -s (DIFFPLUG_INSTALL_DIR)/dp /usr/local/bin/dp on linux.
    • ln -s /Applications/DiffPlug.app/Contents/Eclipse/dp /usr/local/bin/dp on mac.
    • On windows, the dp.exe file can still be copied on its own.
  • Added support for Simulink R2017a.
    • Signal tracing does not yet support the new bus element ports.

Fixed in this release:

  • HTML comments in Stateflow diagrams are no longer displayed.
  • When tracing a Simulink model, the colors return to normal after the diagram is closed.
  • Japanese character encoding issues in Simulink models.
  • Simulink diffs between unusual combinations of text files.
  • Problem with Windows command line installation for specified installation directory.

v1.8.8 is released

New in this release:

  • AUTOSAR files embedded within Simulink models will be included in diffs and diff reports.

Fixed in this release:

  • Several signal tracing problems:
    • Signal tracing still cannot handle feedback loops.
    • However, when a loop is encountered, it will no longer require the tab to be opened and closed.
    • Additionally, double-clicking will no longer automatically extend a trace, which was causing accidental loops.
