Yes, this is a side effect of the timing of the two releases.  SOME
of the fixes (those that seemed appropriate, and were done early
enough) are already part of the 4D35 release.

For cases where the bug fixes don't affect files that are on the
4D35 tape (try 'versions long 4D35' to get the list) you should be
able to install them.  Because some of the files on 3.3.3 might
overwrite files on the 4D35 tape, you should probably re-install
the 4D35 tape AFTER installing 3.3.3, making sure that you do
a 'set neweroverride' first.  Note that this is definitely NOT
something we would recommend (installing 3.3.3 on a 4D35), just a
comment on what would need to be done.

The 4.0 IRIX release has full support for the 4D35, so there won't be
a 4D35 product in that release.  There may be a maintainence tape
for the 4D35, containing support for the audio hardware, and maybe
(I don't know) some of the 3.3.3 changes.  It depends on the timing
with 4.0, etc.


As usual, these are only my opinions, not official SGI statements...
(Got to put one of those in every month or so!)

Life would be so much easier if we could just look at the source code.
