1.17.0 - (2026-05-25)

🕯️ In memory of Cleve Moler (1939–2026)

This release is dedicated to the memory of Cleve Moler, creator of MATLAB and a towering figure in numerical computing. His vision of making linear algebra accessible to engineers and scientists changed the way the world writes scientific software and inspired every project that followed in his footsteps, including Nelson.
We are grateful for the path he blazed.

Added

  • function argument validation using arguments ... end blocks

    • Support for validation functions (e.g., mustBeNumeric, mustBeMember)
    • Default values for optional positional and name-value arguments
    • Separate validation blocks for input and output arguments
    • Improved error messages for invalid function arguments

  • Debugger Support

    • Full breakpoint management with commands: dbstop, dbstep, dbcont, dbquit, dbclear, dbdown, dbup, dbstatus.
    • Support for setting breakpoints at specific files, functions, and lines.
    • Conditional breakpoints and hit-count breakpoints (if applicable).

  • Interactive Debugging in Text Editor

    • Real-time feedback on breakpoints directly within the editor.
    • Inline variable inspection while stepping through code.
    • Highlighting of the current execution line.

  • Step Execution Controls

    • Step Into: move into function calls.
    • Step Over: execute functions without entering them.
    • Continue: resume execution until the next breakpoint.

  • Stack Inspection & Variable Evaluation

    • Examine the call stack during debugging with dbup and dbdown.
    • Evaluate and modify variables in the current workspace.

  • contourf, contourc, Filled contour plot of matrix.

  • Dedicated Windows Terminal profile installed for the application.

  • help engine extending to manage subchapters.

  • xmldoclinkchecker Checks unresolved cross-references in Nelson help XML files.

  • MacOS packaging as dmg installer.

  • Qt 6.11.0 support.

  • Full CMake configuration and build system for Visual Studio (x64, Win32, ARM64).

  • Ubuntu 26.04 ready.
