System 97 is now released.

[Richard M. Stallman <RMS@MIT-OZ>]

Documentation for System 97 is in OZ:SRC:<L.DOC>SYS97.MSG.
I have been using system 97 for a month, and it is pretty solid.
Make sure you use a band that uses microcode 257!
Good sources of these are CADR1 and CADR18.

The current version is 97.6.

The most interesting improvements are:

 A new Common-Lisp-compatible package system.

 An improved undo facility,
  the best an editor has ever had.

 Incremental band saving:
  save just the differences between your world
  and the system you loaded, in a small partition.

There are some incompatibilities, mostly due to Common Lisp,
 so make sure you read SYS97.MSG.
