Release Notes — Line Segmentation & connectNulls Support

Highlights

• Line & Area Segmentation via null gaps — Lines and area series can now be visually broken into discrete segments by inserting null entries into your data array. This enables accurate representation of missing data, maintenance windows, trading halts, and session boundaries without hacking around the data model.
• connectNulls option — A new connectNulls boolean option on line and area series lets you toggle between bridging over null gaps (legacy behavior) or rendering true visual breaks (new default). Works with both array and columnar data formats.
• WebGPU shader-level gap detection — NaN/null gap awareness is now built directly into the line vertex shader and area vertex generation, ensuring GPU-side rendering correctly handles discontinuous data with zero CPU overhead per frame.
• Sampling bypass for gapped data — The data pipeline automatically detects null gaps and bypasses the sampling stage to preserve segment boundaries, preventing gaps from being silently dropped during downsampling.
• New exchange-gaps example — A fully interactive demo showcasing exchange maintenance gaps, connectNulls toggling, multi-asset outages, and trading session concatenation.
