// CHANGELOG

Shipped recently

Track updates and new features.

v1.4.0

React PDF Highlighter Plus v1.3.0

2026-07-04

Verso Design System

Every highlight type restyled on a shared token set

•New light + dark color, radius, shadow, and typography tokens
•Text, Area, Freetext, Image, Drawing, Shape, SignaturePad restyled
•Color dropdowns, lucide icon set, rotate for image/drawing

PDF Export Overhaul

Exported PDFs now match what you see on screen

•SVG image highlights are rasterized (previously silently dropped)
•Rounded corners on Text/Area/Freetext/Image/Drawing exports
•Per-type object-fit: images stretch to fill, drawings keep aspect

Transparent Signatures & Drawings

Ink-only rendering, matching shape highlights

•No more white card behind a signature or freehand drawing
•Signature/drawing now reads over the page like an arrow or box

Simpler Draw & Shape Tools

No more pre-draw configuration panel

•Removed the color/width panel and on-canvas control bars
•Draw or place a shape first, then adjust it from its own toolbar
•Shapes commit on release; drawings commit when you finish; Escape cancels

Smoother Zoom

Fewer, coalesced re-rasters while wheel/pinch zooming

•A notch train now commits once instead of on every notch
•Eliminated a redundant second re-raster per zoom gesture

Highlight Duplication Fix

A same-page highlight no longer renders multiple times

•Fixed a page-grouping bug that stacked overlapping copies
•Previously made translucent highlights look solid/opaque

Technical Changes

• Updated `react-pdf-highlighter-plus` from v1.2.0 to v1.3.0
• Deduplicated page grouping in `group-highlights-by-page`
• `exportPdf`: SVG rasterization, rounded-rect fills, per-type object-fit compositing
• Removed `FloatingActions` pre-draw options panels and on-canvas Drawing/Shape control bars
• Wheel-zoom: longer commit-coalescing delay, no-op guard, removed a redundant scale re-application

v1.3.0

React PDF Highlighter Plus v1.2.0

2026-06-29

Hue-Preserving Dark Mode

Pages recolor at render time (OKLab) instead of a CSS invert filter

•Colors keep their hue; embedded photos keep their pixels
•Configure via theme.darkModeColors { background, foreground }
•Highlights stay readable; LeftPanel gains a mode prop

Citations

Turn any quote into a precise highlight with getTextPosition

•Whitespace-insensitive matching with a fuzzy fallback

Speak the document and follow each sentence

•Highlights + auto-scrolls to each sentence as it's read
•Play / pause / seek / speed / voice transport
•Pluggable TTS engine (browser voice now, cloud later)

Zoom, Smooth Scroll & Deep Linking

Pinch zoom, animated scroll, and ?page=N links

•Pinch / ctrl(⌘)+wheel zoom, smooth via GPU transform
•scrollToHighlight animates and respects reduced-motion
•initialPage + onPageChange for deep links

Faster Loading & Stability

Progressive loading, caching, and render fixes

•PdfLoader: range loading, auth headers, document cache
•Fixed a React-root render warning + a memory leak
•Less re-rendering while scrolling annotated documents

Technical Changes

• Updated `react-pdf-highlighter-plus` from v1.1.4 to v1.2.0
