Elegant users forum

Version 20.0 of elegant has been released on our web site at http://www.aps.anl.gov/asd/oag/software.shtml, for
all platforms except OS-X (which will follow shortly).

In addition to several bug fixes, some significant new features are available: A new element (MBUMPER) was added to permit simulation of
time-dependent multipole kickers. The undulator kick map (UKICKMAP) element now includes synchrotron radiation effects. Orbit and
trajectory correction now uses SVD. Computation and optimization of resonance driving terms is now supported.

For details, see the manual at http://www.aps.anl.gov/asd/oag/manuals/ ... egant.html

Several users have reported a bug in elegant 20.0 that impacts orbit correction under some cases (apparently response matrix generation during optimization).

This bug is confirmed and is under investigation.
