The CBFlib release at

   http://www.bernstein-plus-sons.com/software/CBF

has been upgraded to CBFlib_0.7.7 subrelease 0.7.7.4 of 6 May 2007.

For those used to CBFlib_0.7.6.1, this is a major revision, with
an implementation of byte offset compression, and extension of
the packed compression, support for reading with f90 routines,
support for 3d images, and much faster I/O.  A draft of the
latest draft imgCIF dictionary (version 1.5.2) is included
and can also be seen at

   http://www.bernstein-plus-sons.com/software/CBF/doc

For those who have already been using CBFlib_0.7.7, the changes
in this version are to correct an error in the ordering of dimensions
in some image writes, and adjust the ordering of dimension
declarations versus the actual array declarations to work with
more f90 compilers.  The draft dictionary has been updated
too include the latest suggestions from the recent discussion
on the imgcif list.

Our thanks to:

   W. Kabsch for the f90 implementation of A. Hammersley's
byte offset compression and the initial F90 code to read
CBFs,
   J. P. Abrahams and CCP4 for permission to incorporate the
logic of packed_c.c into CBFlib under the gnu open source licenses,
   E. Eikenberry for a very fast C-implementation of byte offset
compression and for helpful suggestions in speeding things up
in general,
   H. Powell for pointing out the need to reorder the F90 declarations
   A. Hammersley and J. Wright for many helpful suggestions, especially
with respect to beam centering and real arrays,
   and these people and many other members of the community for testing
and suggestions and a great deal of patience as we work though problems.

   Bug reports, comments and suggestions would be much appreciated.
