While it's nice that web developers don't seem to be using the build type info in the user agent string in their code, user agent parsing code is still very brittle. Some browsers, like Firefox, have had buildtype characters in the user agent string for many years, so parsing code can handle things like "Firefox/14.0a2". But Chrome hasn't ever changed its version format, so we're worried about breaking user agent parsers. _______________________________________________ webkit-dev mailing list [email protected] http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
