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
