Siesta Bethe-Salpeter

Dear Developers
Is there a Siesta release that is able to calculate absorption spectra as was done and published in Phys. Rev. B 92, 075422 (2015) - Cubic-scaling iterative solution of the Bethe-Salpeter equation for finite systems ?

Best Regards.

Dear Luca,

I am sorry to say, but there is no such SIESTA version.

Best regards,
