Dear Colleague,
 
Some updates to DL_MESO 2.7 have been made and are now available for registered 
users to download as a revised version of the package (2.7 rev 05). You do not 
need to re-register for this update if you have previously registered for 
an earlier form of version 2.7: the revised package can be downloaded from the 
same location as before and decrypted using the same password. If you would 
like to use version 2.7 but have not yet registered for this version (e.g. if 
you have previously registered for version 2.6), please do so via the link from 
the DL_MESO website at www.ccp5.ac.uk/DL_MESO
 
Changes made to DL_MESO include bug fixes in the LBE code for Swift free-energy 
interactions (specifically the parameters used for local equilibria for 3D 
lattices, gradient calculations and implementations of Inamuro and kinetic 
boundary conditions) and Lishchuk wall wetting forces, an additional error 
message in the DPD code to catch missing "finish" directives in FIELD files 
when defining molecules, a bug in the Java GUI when reading wall interaction 
parameters from the input file lbin.sys and a correction to the expression for 
the exact Slater-type smeared charge potential in real space in the user manual. 
(Many thanks are due to Martin Bates at the University of York for the 
correction to the charge potential expression, Karel Sindelka at ICPF in Prague 
for the suggestion of the additional error message, and Ehsan Kian Far at the 
University of Manchester for identifying the LBE code bugs and suggesting 
fixes.) Additional updates to the user manual have also been made.
