Version 16.0 of elegant has been extensively modified from previous versions, although few changes should be noticed by users. This is largely due to code changes required for parallelization. A parallel version will be released in the near future. Users may note that particles in output files are sorted by particle ID, which was not the case in past versions.
In addition, several significant new capabilities have been added, including coupled twiss parameter computation and determination of s-dependent momentum aperture.
Here is a summary of what's changed since release 15.4.1. For details and references, see the specific entries in the manual.
