🚀 New Features

• External dashboard windows: Open multiple independent dashboard windows from the Start Menu for multi-monitor setups. Each window has its own widget layout with geometry persisted automatically.
• Auto-hide toolbar: New option to collapse the toolbar with a smooth animation when the dashboard is visible, maximizing screen space for widgets.
• Axis range configuration: New dialog for Plot, MultiPlot, and FFT Plot widgets to customize X/Y axis ranges. Reset button restores zoom and axis ranges simultaneously.
• MCP protocol support: API server (port 7777) now speaks Model Context Protocol (JSON-RPC 2.0) in addition to the legacy protocol, enabling AI agent integrations (e.g. Claude). 182 tools, 2 resources.
• Vector & scalar support in frame parser (#281): Frame parser can now handle mixed scalar/vector data, automatically expanding a single packet into multiple frames (e.g., batched sensor data with 120 samples in one packet).
• Cursor tracking and tooltips: Gauge, Bar, and Accelerometer widgets now show interactive crosshair cursors and value tooltips on hover.
• Overhauled gyroscope and accelerometer widgets: Redesigned visuals with direction indicators (↔ ↻ ↕) on gyroscope labels, improved zoom behavior distinguishing touchpad vs. mouse wheel, and better layout.
• RC Plane Simulator example: New example project demonstrating multi-frame batched sensor parsing with the gyroscope and accelerometer widgets.

🐛 Bug Fixes

• Dashboard shown instantly on first frame: Removed 500 ms delay and fixed a race condition where the first frame's dashboard configuration was wiped on connect.
• GPS altitude bug: Fixed inverted NaN check that caused valid altitude values to be silently discarded.
• UDP memory leak on Windows: Reuse a single buffer for UDP datagrams instead of allocating per datagram, eliminating heap fragmentation at high frequencies.
• Frame parser reset on new project: Creating a new project now correctly resets the frame parser code to the default template.
• Frame parser false positives: Evaluation check now tests multiple frame argument types to avoid incorrectly flagging valid parsers as broken.
• Console ANSI colors: Debug messages now respect the ANSI colors/VT-100 user setting instead of always rendering color codes.
• Plot rendering with NaN/infinity: Non-finite values in plot widgets are now validated and skipped to prevent rendering artifacts.
• API rate limit enforced: Fixed rate limit enforcement (was 10,000 msg/sec, now correctly 200 msg/sec). Added batch request validation with 256-item limit.
• Project Editor modification flag: Resetting the frame parser via button or shortcut now correctly marks the project as modified.
• Fix Gyro Widget rendering incorrect values: Address latest comment in issue #296 by redesigning the widget.

Full changelog: v3.2.1 → v3.2.2

This patch release fixes a critical bug in hexadecimal frame delimiter detection that was introduced in v3.2.0.

🐛 Critical Bug Fix

• Fixed Hexadecimal Frame Detection (#335): The frameStart and frameEnd sequences were incorrectly swapped when using hexadecimal delimiters, causing frame detection to fail completely. This affected all projects using hexadecimal frame delimiters (‎app/src/JSON/Frame.cpp).

Thanks to @SvenNouwens for reporting this issue!
