Abstract: An overview of opacity calculations performed during the past decade is presented. Attention is given to envelopes and interiors, equations of state, atomic data, line profiles, and mesh points. Results for a Cepheid model are presented. The solar radiative interior, solar abundances, hydrogen and helium, and contributions from the different elements are discussed. Work over the past decade has led to major revisions in envelope opacities, by factors as large as 3 or 4. There are also some revisions in results for deeper layers, which are important but not so pronounced. A comparison of the work of two opacity research groups, OPAL from the Lawrence Livermore National Laboratory and the international OP project, is given.
