Version 2.50.1 - #615: SVG2: Support a chain of uri() filters in the "filter" property (John Ledbetter, Sven Neumann). - #483: Support CSS selectors for attribute matching, like rect[attr^="prefix"] - #554: Fixed the geometry_for_layer() APIs to not ignore the passed viewport. - Fixed CSS "import" so it allows only files from the same base directory (Lars Schmertmann). - #623 - The pkg-config files (*.pc) do not define the 'svgz_supported' and 'css_supported' variables anymore. These variables were hardcoded to 'true' and unchanged since 2011. - #624 - The source repository no longer produces a librsvg-uninstalled.pc file.
