Beta version 0.10 of Mosaic, NCSA's X/Motif-based networked
information systems browser, including full source code and binaries
(for SunOS 4.x, SGI IRIX 4.x, AIX 3.2, and DEC Ultrix), is now at in /Web/xmosaic:


NCSA Mosaic provides a consistent and easy-to-use hypermedia-based
interface into a wide variety of information sources, including
Gopher, WAIS, World Wide Web, NNTP/Usenet news, Techinfo, TeXinfo,
FTP, local filesystems, Archie, telnet, tn3270, and others.  A list of
changes made since version 0.9 follows this canonical features list:

 o Support for accessing documents and data through Gopher, WAIS,
   World Wide Web, FTP, NNTP/Usenet news, Techinfo, TeXinfo,
   Telnet, tn3270, Archie, NCSA DMF, local files, and other sources.
 o Friendly X/Motif user interface.
 o Color and monochrome default X resource settings.
 o Multiple independent toplevel windows.
 o History list per window (both 'where you've been' and 'where you
   can go').
 o Global history with previously visited locations visually distinct;
   global history is persistent across sessions.
 o Hotlist/bookmark capability -- keep list of interesting documents,
   add/remove items, list is persistent across sessions.
 o Personal annotations with GUI annotation entry dialog; annotations
   can later be edited or deleted, and hyperlinks to existing annotations
   are inlined into subsequent accesses of an annotated document. (Note:
   any document from any server via any access method can be
 o Audio (voice) annotations with GUI for controlling recording process
   (SGI and Sun only).
 o Support for recognizing and handling GIF, JPEG, TIFF, audio, AIFF,
   DVI, MPEG, MIME, XWD, RGB, PostScript documents and forking
   off appropriate viewers.
 o Transparent and automatic uncompression of compressed (.Z) and
   gzip'd (.z) files.
 o Inlined images in formatted (HTML) text: X bitmaps and GIF images
   can be included anywhere inside a document, and can act as hyperlink
   anchors. Image files themselves can be located anywhere on the
 o Binary transfer mode, for pulling down arbitrary binary files and
   saving them to local disk without viewing them.
 o In-document search capability.
 o Fully 8-bit clean for formatted and plain text.
 o Options for new window per document (aka TurboGopher interface)
   -- always, or via middle mouse button.
 o On-the-fly font and hyperlink style selection.
 o Many common document and data source choices accessible via
 o Keyword search capability (for WAIS, Gopher, Archie, etc.).
 o Cut and paste formatted text into other X windows.
 o Smart handling of documents too big for single X window -- virtual
   document pages via inlined hypertext.
 o Save/mail/print documents in several formats.
 o Online hypertext help and FAQ list.
 o No config or resource file installation required; self-contained
 o Extremely customizable.
 o Integrated with NCSA Collage and NCSA DTM to broadcast
   documents into real-time networked workgroup collaboration

A list of changes made from version 0.9 to version 0.10 follows:

 o Support for <IMG> tag: inlined images in HTML documents.
    o Handles X bitmap and GIF formats so far.
    o New resource, colorsPerInlinedImage, can be used to restrict
      color use of inlined images -- default is 50.
    o Image files can be located anywhere on the net (pointed to by
      URL); image data is cached in memory for fast display and
    o Example of inlined bitmap:
      <IMG SRC="file://">
    o Example of inlined image serving as anchor:
      <A HREF="">
      <IMG SRC="file://"> </A>
 o Better support for acting as binary file retrieval client.
    o Each window can either be in binary transfer mode or not;
      resource binaryTransferMode controls startup value (default
      is 'False', and you probably don't want to change this). A
      toggle button in the Options menu allows changing on the fly.
    o If a window is not in binary trasfer mode, data files with
      unrecognized types will be displayed in the window as either
      plain text or HTML (depending on the server type), as before.
    o If a window is in binary transfer mode, data files with
      unrecognized types will be dumped to a local file after being
      transferred over as binary data.
    o Regardless of whether a window is in binary transfer mode or
      not, files with recognizes types (images, sound, etc.) will be
      handled as usual, and uncompression will be transparent as
    o The whole point of all this is to allow the user to select on the
      fly how a given file of an unrecognized type is to be handled.
    o Because files are currently typed by filename extension,
      binary transfer mode should generally be kept off, otherwise
      it will screw up things like WAIS searches pretty badly. Also,
      since Gopher does things differently from everyone else,
      things are different there too.
    o Setting one of the multimedia resources to the text string
      "dump" will cause files of that type to be dumped to local
      disk as though in binary transfer mode.
    o See
      for a more thorough discussion of these issues.
 o Audio annotations for Sun's with /usr/demo/SOUND/record (or
   something similar) are now enabled. Resources
   recordCommandLocation and recordCommand are used to specify the
   command used to record sound; theoretically, this approach can be
   used on any platform with appropriate hardware and software,
   although SGI Indigo & Sun Sparcstation are the only two that I know
 o Search capability within documents: enter search term, scrollbar
   jumps to match and match is highlighted; repeat as desired.
 o Enhanced support for various Gopher types, including binary files
   and CSO phonebooks (sorry, phonebooks aren't supported yet, but at
   least now an error message shows up).
 o Spaces converted to +'s in keyword queries now.
 o Scrollbar arrows now increment a reasonable amount when viewing
   large documents.
 o Anonymous FTP password is now always user@host.domain,
   enabling access to every strange FTP server out there that I know of.
 o Pattern-matching to determine file type based on file name now uses
   caseless string compare.
 o Better default visited anchor color for non-SGI color displays.
 o Messages from libwww now show up in pop-up dialogs like they
 o Telnet never gets asked to use unrecognized -l flag.
 o Tar files are now always retrieved to local disk (and not displayed).
 o Replacement (and better) Archie interface.
 o Mail Developers window is cleared on each use.
 o New resource trackVisitedAnchors; can be used to turn off tracking
   of visited anchors altogether.
 o Better transparent uncompression support:
    o Gzipped (.z) files are now recognized and uncompressed on
      the fly (as well as .Z files, as before).
    o New resources uncompressCommand (default 'uncompress')
      and gunzipCommand (default 'gunzip').
 o As usual, little bugfixes and cleanups.

Finally, thanks *again* to everyone who's been contributing comments
and bug reports -- keep 'em coming!
