                      ------ OUT NOW ! ------


The latest version of the CCP4 Suite for protein crystallography is
now available on the CCP4 anonymous ftp server (ccp4a.dl.ac.uk or
148.79.112.134 -  cd pub/ccp4). The CCP4 Suite is mirrored at
rosebud.sdsc.edu (directory /pub/sdsc/xtal/CCP4 ), but please
allow some time for the mirror site to be upgraded to the new
version.

The new version includes a significant addition to the MTZ format,
namely the use of Missing Number Flags (MNF) to indicate missing data.
Most programs now read and write MNFs, and it is recommended that
MNFs are incorporated into existing data files using the jiffy MTZMNF.
With a policy for handling missing data, it is now straightforward
(and strongly recommended) to work with complete datasets, i.e. to
include all reflections up to the high resolution limit whether
or not the corresponding datum is present (see the UNIQUE documentation
for more details). A Users' Guide to MNFs can be found at
http://www.dl.ac.uk/CCP/CCP4/user.html

In addition to improvements to existing programs, there are a
number of new programs. In particular, have a look at:

1) RESTRAIN from the Birkbeck group: refinement program including,
                                     amongst many options, TLS refinement.

2) REFMAC from Garib Murshudov: Maximum Likelihood refinement program.

3) SOLOMON from Jan-Pieter Abrahams and Kevin Cowtan: density modification 
                                     program using solvent flipping.

4) XDLDATAMAN, XDLMAPMAN from Gerard Kleywegt: manipulation and reformatting
                                     of data and map files.

Details of all the changes can be found in the CHANGES file in the
top-level directory ($CCP4).
