Big Faceless PDF Library 2.10.3
The ability to write Linearized (also known as "Web optimized") PDFs was added. The PageExtractor class was rewritten completely; it is now faster, better, and works with rotated documents. A problem which caused increased memory usage when using a PDFReader in a single thread was fixed. The difference can be significant, so anyone in this situation is encouraged to upgrade. Significant improvements were made to the behavior and appearance of the Viewer, giving more reliable results across the board.
