4.3.0

Released 29th June 2026

Main features

  • Add support for FTDI JTAG controllers.
  • Allow licences to be served from the internet for evaluations.
  • Add support for XJLink-PF20 and XJLink-PF40 in Chain Debugger, XJAnalyser and the Manually Create Board wizard in XJDeveloper.

Smaller enhancements and bug fixes

  • XJDeveloper:
    • Boards Screen: Fix an issue where it was possible for the manually created board wizard to select the wrong netlist on completion.
    • JTAG Chain Screen: Allow any number of JTAG chains to be defined without a supporting pin mapping yet defined.
    • Don’t automatically open the Add Board dialog when creating a new project or opening a project without any boards defined.
    • Prompt to create a different pin mapping type when creating a new project with hardware attached that does not match the default pin mapping type selected in the application options.
    • Add an application option to set the default pin mapping type to create for all new projects.
    • Fix an issue where selector dialogs were not parented correctly to the Explorer window and closing the Explorer window would leave the main application unusable.
    • Improve the amount of diagnostic information in the XJDeveloper actions log file.
  • XJAnalyser:
    • Remove the ability to import pre-v3.0 projects.
    • Do not copy BSDL files from the library if the user opts not to copy them.
    • Remember previous device settings when editing the JTAG chain.
    • Fix a crash attempting to run with an XJLink type that is not supported by the project.
    • Fix a potential crash after editing JTAG chain with constant pins defined.
  • Layout Viewer: Ensure the Export, Print and Print Preview dialogs are parented correctly.
  • XJLink Manager: Improve saving of application layout settings.
  • XJIntegration:
    • Change the XJLink.SerialNumber property to be a string rather than a uint, so increment the assembly version to 3.0.0.0 due to the breaking change.
    • Ensure that the Runner.OutputFromLastTestRun property is always reset when running multiple functions.
    • Fix potential unnecessary memory usage when opening projects and running code in a tight loop.
    • Fix an memory management issue in the Single Test Run VI.
  • XJPack: Modernise the command-line switches, replacing various switches with a single dash with two dashes, but keeping the old ones for compatibility.
  • XJRun: Modernise the command-line switches, replacing various switches with a single dash with two dashes, but keeping the old ones for compatibility.
  • XJEase:
    • Allow CALL statements with non-constant values for the device reference and function name.
    • Allow CALL statements inside test device files.
    • Add FUNCTION_EXISTS function to determine if a test function exists for a specific test device.
    • Fix GET_DEVICE_TYPE function to return a more consistent value when a device has multiple categorisations.
    • Add a method to allow external APIs to print formatted text.
    • Add a method to allow external APIs to open files from inside XJPack files.
    • Ensure that when constant integer expressions are evaluated by the compiler, the width of the resulting value is consistent with what happens wen evaluating the same expression using non-constant values at runtime.
    • Improve error messages for invalid device references.
  • Projects: Write all devices onto separate lines in board files, to help viewing diffs and handling merges in source control systems.
  • Ensure that the correct build date is displayed in any error log that is generated.
  • Installer: Remove standalone Layout Viewer application.
