For a full list of known issues, see the issue tracker.

Installation Notes

• Starting with DOMPDF 0.6.0 the dompdf.php script will no longer allow conversion of HTML document on the local file system that are located outside of the path specified by DOMPDF_CHROOT
• If you are installing DOMPDF on top of an existing installation you should remove any existing font metrics. This can be done manually or through the sample website (www/fonts.php).
• When upgrading to a new version of DOMPDF you must replace dompdf_config.inc.php with the new one. To simplify the upgrade process you can store your configuration settings in dompdf_config.custom.inc.php (which does not need to be overwritten).

DOMPDF 0.6 Roadmap

• Improve Unicode support
• Improve page breaks inside or outside tables
• Improve support for CSS float
• Reduce memory usage
