Version 1.1: this now includes models that experience quasi-homogeneous evolution at the lowest metallicities of Z=0.001 and 0.004. The version and results are outlined in:

• Eldridge & Stanway, 2012, MNRAS, 419, 479. The effect of stellar evolution uncertainties on the rest-frame ultraviolet stellar lines of C IV and He II in high-redshift Lyman-break galaxies.
• Eldridge, Langer & Tout, 2011, MNRAS, 414, 3501. Runaway stars as progenitors of supernovae and gamma-ray bursts.
• Stanway et al, 2014, MNRAS, 444, 3466. Interpreting high [O III]/H β ratios with maturing starbursts.

Version 1.0: this was the first version of the code. The models and synthesis code are outlined in the following papers:

• Eldridge & Stanway, 2009, MNRAS, 400, 1019. Spectral population synthesis including massive binaries.
• Eldridge, Izzard & Tout, 2008, MNRAS, 384, 1109. The effect of massive binaries on stellar populations and supernova progenitors.
