Item 1. 
========================


ATOMDB Version 1.2.0 Released

The CXC announces the release of ATOMDB v1.2.0, consisting
of new atomic data and calculated spectra.  For complete details,
check out the revised ATOMDB website http://cxc.harvard.edu/atomdb.
This release contains new wavelengths for the Ni L-shell lines, using
NIST data, as well as additional data for the lithium-like ions of Ne,
Mg, Si, and S, also based on new NIST data and HULLAC calculations by
Duane Liedahl.  We have also included many more references, using the
popular ADS bibcode format.  The ATOMDB website includes for the first
time a list of density-dependent lines, comparisons of ATOMDB spectra
to other common spectral codes such as Raymond-Smith and SPEX, as well
as updated documentation describing the ATOMDB and its components APEC
and APED.
