Dear all,

BDSIM V1.6 is now tagged and released in the git repository. You can find the code, 
update instructions and a list of changes at the following links:

http://www.pp.rhul.ac.uk/bdsim/manual/history.html#v1-6-0-2021-06-16

Some of the most interesting new features are even more options to 'paste' on 
biasing to different volumes; control over which trajectory variables are written out;
bdskim - a skimming tool; and a new command /bds/samplers/view to make sampler 
viewing easier.

=====================================================
New Examples
=====================================================

More detailed worked examples have also been added to cover the most common 
workflows, with each listing a brief set of topics covered at the top. See:

http://www.pp.rhul.ac.uk/bdsim/manual/examples.html#worked-examples

=====================================================
CVMFS - A Public Installation
=====================================================

There is now a setup of BDSIM on the worldwide accessible CERN Virtual Machine
File System (CVMFS), which is commonly used at many high energy physics
labs and universities. Details can be found in the manual here:

http://www.pp.rhul.ac.uk/bdsim/manual/installation.html#centos-7-with-cvmfs-access

and the root directory is: /cvmfs/beam-physics.cern.ch/bdsim/

To use this, you must have cvmfs accessible and source a single script. All the tools
and commands will then be available.

Currently, this software will work for any CentOS7 machine and includes a complete
environment including BDSIM, Geant4 with the Qt visualiser, ROOT, IPython and our
various python utilities.  

=====================================================
Custom Geometry
=====================================================

A Python package worth highlighting is pyg4ometry. Also started at Royal Holloway,
this is a package to aid in the preparation and conversion of custom geometry that 
can be used in Geant4 and FLUKA. Separate from BDSIM, but useful for custom GDML 
elements as well as converting FLUKA geometry to GDML. Furthermore, conversion
from select CAD formats is provided too. Simple pieces of geometry can be written 
in a Python script, checked for overlaps, visualised (including seeing any overlaps) 
and exporting in an afternoon. See:

This email list is used only on occasion for BDSIM releases and news. I will attempt
