"URI handler, a important bug fix in the FTP plugin, and a cookies server\n"

"<li> Designed and implemented a dpi protocol library (libDpip.a in /dpip).\n"
"<li> Ported the bookmarks, download, file, https, ftp and hello plugins,\n"
"     plus the dpid daemon and the rest of the source tree to use it.\n"
"<li> Improved the dpi buffer reception to handle split buffers (This was\n"
"     required for handling arbitrary data streams with dpip).\n"
"<li> Fixed a serious bug with the FTP plugin that led to two downloads\n"
"     of the same file when left-clicking a non-viewable file.\n"
"<li> Improved the accuracy of the illegal-character error reporting\n"
"     for URLs.\n"
"<li> Added dpi/downloads.cc (Default FLTK2-based GUI for downloads dpi).\n"
"<li> Added \"./configure --disable-dlgui\" to build without FLTK2-GUI\n"
"     downloads.\n"
"<li> Fixed dpip's tag syntax and its parsing to accept any value string.\n"
"<li> Added DOCTYPE parsing (for better bug-meter error messages).\n"
"<li> Fixed bookmarks dpi to escape ' in URLs and &<>\"' in titles\n"
"     (BUG#655).\n"
"<li> Added a check for malicious image sizes in IMG tags.\n"
"\n"
"<li> Added a datauri dpi to handle \"data:\" URIs (RFC-2397).\n"
"<li> Moved the cookies management into a dpi server: cookies.dpi.\n"
"<li> Removed the restriction of only one dillo with cookies enabled!\n"
"<li> Added \"./configure --disable-threaded-dns\" (for some non\n"
