NetSurf 3.5 is primarily a bugfix release. It contains several fixes and clean-ups to front end code, as well as an improvement to URL parsing. We recommend all users upgrade to NetSurf 3.5. NetSurf is a free, open source web browser. It is written in C and released under the GNU Public Licence version 2. NetSurf has its own layout and rendering engine entirely written from scratch. It is small and capable of handling many of the web standards in use today. The NetSurf project was started in April 2002 in response to a discussion of the deficiencies of the RISC OS browsers that were available at the time. NetSurf has been developed continuously ever since. The latest features and bug fixes have always been available immediately to users through the project’s autobuilder. NetSurf had become the most widely used browser on RISC OS well before NetSurf’s first release, version 1.0, on 17th May 2007. Development builds have continued to be more widely used than release versions by RISC OS users.
