Version 4.5.0 - Arrays, Callable Equations & Large File Workflows

This release expands attribute calculations with array values and callable code-backed equations, improves SysML v2 export coverage, and makes large file workflows more resilient.

Attribute Values & Equations

  • Added array-valued attributes for numeric and boolean data
  • Added support for 1D vectors, 2D matrices, and 3D arrays while keeping strings and dates scalar-only
  • Added callable attribute equations that can invoke code object functions using syntax like [codeUuid].method(arg1, arg2)
  • Added support for Python and JavaScript functions to receive resolved attribute values and return a calculated value
  • Expanded equation outputs to support numbers, dates, booleans, strings, and arrays of numbers or booleans
  • Added unitful return support with { value, unit } results from code-backed calculations
  • Added stale-value warnings for attributes that depend on code-backed calculations

SysML & Modeling Interoperability

  • Improved SysML v2 export for callable code-backed calculations
  • Added preflight warnings so export issues can be reviewed before generating SysML output

Files, Imports & Code Execution

  • Added a large-workbook flow for Excel import
  • Increased the upload limit from 1 GB to 2 GB
  • Added configurable code file I/O limits with streaming support for larger code workflows

Editor & Agent Experience

  • Added a warning for non-Chromium browsers
  • Improved chat and thought streaming
  • Improved history and diff rendering
  • Improved large value and error display handling
