Release Notes: Space could be added after some non-whitespace symbols immediately followed by inline boxes. Under certain circumstances, custom characters were ignored in CSS3 margin box content. Some temporary files were not removed when using the fpdf output method. All of these problems have been fixed.
Release Notes: The number of custom characters is no longer limited to 256 symbols per file. Characters with AI, SA, SG, and XX line breaking classes no longer result in notice messages.
Release Notes: A large number of layout engine fixes and improvements were made.
Release Notes: An experimental CSS handling module was added.
Release Notes: Several minor changes in tables / textarea rendering routines. Proxy support is out-of-the-box now (provided you have the curl extension installed).
