Version 1.0 of NCSA Mosaic for the X Window System, a networked
information systems and World Wide Web browser, is hereby released:


Changes since beta version 0.13 include:

o Added new resource, gethostbynameIsEvil, for Sun's that
coredump when gethostbyname() is called to try to find out what
their own names are. (Command-line flag is -ghbnie.)
o Explicitly pop down all dialog boxes when document view
window is closed, for window managers too dull to do so
o Better visited anchor color for non-SGI's.
o Added .hqx and .uu to list of file extensions handled like .tar files.
o Added 'Clear' button to Open box, to allow more convenient
cut-n-paste entries of URL's.
o New resource 'autoPlaceWindows'; if set to False, new document
view windows will not be automatically positioned by the
program itself (but it's still up to your window manager just how
they're placed).
o Command-line flags -i and -iconic now have desired effect (new
resource initialWindowIconic can also be used).
o Gif-reading code is a little more bulletproof.
o Obscure infinite loop triggered by extra space in IMG tag fixed.
o Eliminated nonintuitive error message when image can't be read
(inlined NCSA bitmap is indication enough that something's not
right for authors, and readers can't do anything about bad images
in any case).
o Obscure parsing bug (for constructs like <ADDRESS><A
HREF=...>text<A></ADDRESS>) fixed.
o Fixed mysterious stupid coredump that only hits Suns.
o Fixed stupid coredump on URL's like '://'.
o Fixed buglet in handling rlogin URL's.
o New support for Solaris/SYSVR4 (courtesy
o Better support for HP-UX 8.x and 9.x (courtesy
o Better support for NeXT (courtesy
o Some miscellaneous portability fixes (courtesy
o Miscellaneous bug fixes and cleanups.
