Version 2.1l represents an update to the atomic data which includes the iron and oxygen inner shell data which was presented in 2004 Ap. J. Supp. 155, 675, along with the line data for iron from Chianti 5 and features from version 2.1kn6. Recent updates include fixes to buge in the routines associated with xstar2xspec. These caused numerical problems on 64 bit machines, and also resulted in errors when large grids of models were run. Versions 2.1l, 2.1lnx, etc. have not yet been completely tested and so have not been put into the standard release.
