Here's a summary of changes from the last few months: It's been a long time since the last changes summary post, and a lot has happened since, including Google Summer of Code and ports to new operating systems, so there's a lot to get though here. The new ports are native front ends for AmigaOS and BeOS/Haiku. I'll provide more information about them in a separate post. The Google Summer of Code (GSoC) activity has been a great success. Our students have completed the new HTML5 parser, vastly overhauled the GTK front end, implemented PDF export, added print functionality to the GTK version and split bits of NetSurf out into separate libraries, for ease of maintenance and use by other projects. It's worth mentioning Hubbub before listing the key changes that have happened, as it may be unclear what it does. HTML5 defines exactly how an HTML parser should work when faced with broken HTML, as well as valid HTML. The part about handling broken HTML is based on how the mainstream browsers cope with invalid input. So with Hubbub, we treat broken HTML (i.e. most of the web) like the mainstream browsers. Before Hubbub, NetSurf used an XML parser to parse HTML, but now we actually use a true HTML parser for HTML. So certain instances of valid HTML are now also handled correctly, where they weren't before. The upshot of this is that bugs causing a huge variety of different problems are now fixed. Here's a few examples: Pages that didn't render at all: http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.42.3243 Pages that appeared completely mangled: http://uk.wii.ign.com/ Pages where the text stopped part way down: http://www.ndt-ed.org/GeneralResources/MaterialProperties/UT/ut_matlprop_... Pages where random JavaScript code appeared on the page: http://www.youtube.com/ and many more.
