V5.5.2 (14-April-2026): Overview
This release introduces high-resolution chart export, with support for both colour and black-and-white output, alongside a range of stability, numerical robustness, and analytics improvements across the design environment.
FilterScript Enhancements
- Updated arbmagphase() to include pole flipping support and improved amplitude boundary checks
- Added Whittaker-Shannon fractional delay filter example and the eps keyword
- Added safeguards to prevent chart instability during execution
Signal Analyser — Stability & Correctness
- Resolved a number of issues related to data alignment, scaling, and detector behaviour, particularly when using playbackoffset.
- Fixed CZT detrending exceptions, SG scaling behaviour, and false data clipping warnings
- Improved analytics reliability, including NaN/Inf handling
- Corrected analytics display issues and analyser setting reload behaviour
Algorithm & Analysis Constraints
- BLW tracker now enforces Nyquist-compliant upper frequency limits at lower sampling rates
Deployment & SDK
- Resolved an exception when deploying fixed-point FIR filters in the Arm wizard
- Corrected amplitude scaling issues in fixed-point spectral analysis
