Subject: NCSA X Mosaic 0.5 released
X-Md4-Signature: 73d08d8c8e9930840fefb9989bfe91ac
By the power vested in me by nobody in particular, alpha/beta version
0.5 of NCSA's Motif-based networked information systems and World Wide
Web browser, X Mosaic, is hereby released:


This release of X Mosaic is known to compile on the following

  SGI (IRIX 4.0.2) 
  IBM (AIX 3.2)
  Sun 4 (SunOS 4.1.2 with stock X11R4 and Motif 1.1).

Binaries for these platforms are available on in
/Web/xmosaic/binaries-0.5.  More binaries will be supplied as I am
able to find other Motif-configured platforms to use (DEC MIPS
probably within the next half hour).

Although this is alpha/beta software, I'm looking more for feedback on
design and functionality than bug reports right now -- down the road
the bulk of the program will be rewritten in C++ anyway, so don't take
the current code too seriously.  But bug reports are welcome too.  New
releases will probably come out about every 7-14 days until 1.0

A list of current and future capabilities of X Mosaic follows this
