Thank you for your message and your interest in our models. Our most recent 
available model files can be downloaded from:

http://www.bruzual.org/cb2007_models/

or

http://www.bruzual.org/cb07/

The models in the Updated_version_2012/ subdirectory are identical
to the models in the original_version_2007/ except that the accompanying
*.color files have been updated to include more filters and more model
properties are listed.

These models include the final prescription of Marigo & Girardi
(2007-2008, A&A) for the TP-AGB evolution of low- and intermediate-mass
stars (this produces significantly redder near-IR colors, and hence
younger ages and lower masses, for young and intermediate-age stellar
populations). The models are still preliminary in the sense that we are
also: (1) implementing new libraries of high-resolution spectra in the
optical (the MILES and IndoUS libraries; these will be offered as two new
options to be selected as alternatives to STELIB); and (2) implementing
updated (Padova 2008) stellar evolutionary tracks. The file CB07_models.pdf
includes some details of these models.

In this directory you will also find a new version of the /src directory
of our official 2003 software release, in the file src.tgz, which includes
several improvements and bug fixes relative to the initial version.

These models are not fully public yes, so please refer anyone interested
in using them directly to us. We are of course interested in your
feedback. Please let us know, especially if you have any criticism.

With best wishes,

Stephane & Gustavo
