-Release theme:
-Introduced the QuestPDF Previewer tool - a hot-reload powered, cross-platform program that visualizes your PDF document and updates its preview every time you make a code change. You don't need to recompile your code after every small adjustment. Save time and enjoy the design process! (available only for dotnet 6 and beyond)
-
-Other changes:
-- Improved default word-wrapping algorithm to better handle words which do not fit on the available width,
-- Introduced new word-wrapping option 'WrapAnywhere' that wraps word at the last possible character instead of moving it into new line.
+Implemented support for the text shaping algorithm that fixes rendering more advanced languages such as Arabic. 
+Improved exception message when SkiaSharp throws the TypeInitializationException (when additional dependencies are needed).
+Fixed: a rare case when the Row.AutoItem does not calculate properly the width of its content.
+Fixed: the QuestPDF Previewer does not work with content-rich documents.
