+## [1.0.8] - 2026-06-16
+
+### :rocket: Added
+
+- Add `-Dpi` parameter to `New-AbrDiagram`, allowing the raster output resolution (PNG/JPG) to be set directly via the Graphviz `dpi` graph attribute instead of being fixed at the Graphviz default of 96
+- Add `-IconWidth`/`-IconHeight` parameters to `Add-HtmlNodeTable`, allowing the rendered icon size in a node's HTML table to be set explicitly instead of being derived solely from the source image's pixel dimensions

 ## [1.0.7] - 2026-05-02
