+# jigsawR 0.4.0
+
+## New Features
+
+* **SNIC superpixel puzzle type** with image-aware boundary segmentation and
+  synthetic mode for use without input images (#80)
+* **Voronoi puzzle type** using Fermat spiral cell generation (#42)
+* **Random shape puzzle type** via Delaunay triangulation (#41)
+* **ggplot2 integration**: `geom_puzzle_rect()`, `geom_puzzle_hex()`,
+  `geom_puzzle_conc()`, `geom_puzzle_vor()`, `geom_puzzle_rnd()`,
+  `geom_puzzle_snic()` layer functions with `stat_puzzle()` and
+  `theme_puzzle()` (#54)
+* **Fusion rendering** for all puzzle types including voronoi and random,
+  with `fusion_style` and `fusion_opacity` parameters (#68)
+* **`fill_direction` parameter** for spatial color ordering across piece fills
+* **`fill_palette` parameter** for ggpuzzle geom functions
+* **`show_labels` parameter** for ggpuzzle label display
+* **Min/max tab size constraints** for all puzzle types (#41, #42, #76)
+* **Tabsize normalization** with unified formula and defaults across all
+  puzzle types
+* **Rcpp C++ optimizations** for Bezier curve computation and SVG path
+  translation
+* **RNG batch optimization** integrated into puzzle generators (#65)
+* **Cached segment extraction** for ~40x faster coordinate parsing
+* **Quarto documentation site** with dark mode toggle and gallery pages
+  (#62, #69)
+
+## Shiny Application
+
+* Dark mode support with CSS contrast improvements
+* SNIC puzzle type in navigation
+* Nested accordion UI with slider enhancements (#75)
+* Fusion styling updates without regeneration
+* Voronoi and Random puzzle types in UI (#41, #42)
+* Tab size constraint controls
+
+## Bug Fixes
+
+* Fixed blank PNG rendering in Quarto with `theme_puzzle()` addition
+* Fixed Y-axis inversion for voronoi/random `fill_direction`
+* Fixed fusion edge rendering with lower Bezier resolution for dashed edges
+* Fixed missing boundary strokes and edge segment tracking for voronoi/random
+* Fixed offset parameter wiring through geom functions
+* Fixed blank images when `ggplot()` has no data
+* Fixed gradient test compatibility with ggplot2 4.0 S7 objects
+* Fixed PILES keyword tokenization and row/column piece lookups
+* Fixed size parameter order standardized to `c(height, width)`
+* Fixed `%||%` operator to use rlang
+* Resolved 15 pre-existing test failures
+* SNIC: handle non-matrix labels, platform-robust adjacency tests
+
+## CI/CD
+
+* Full R-CMD-check matrix: windows, macOS, ubuntu (release, devel, oldrel-1)
+* Quarto site publishing workflow
+* Shiny app deployment workflow
+* RCDT archived package handled via `Remotes` field
+* Increased CI timeout for oldrel-1 source compilation
+
+## Documentation
+
+* Quarto documentation site with API/ggpuzzle side-by-side tabsets
+* Responsive SVG embedding with `htmltools`
+* Gallery pages with fusion group examples
+* README redesigned as attractive entry point (#63)
+* GPL-3 license boilerplate expanded
+
+## Internal
+
+* Split `unified_renderer.R` into modular renderer files
+* Consolidated duplicated code across tessellation puzzle types
+* CRAN compliance remediation (#81-#85)
+* Namespace cleanup and performance refactoring
+* Test suite expanded to 2,200+ tests
