There's also Indigo Renderer and the open source LuxRender:

Note that Lux isn’t spectral anymore. The older version is though.
Funny, I added the original implementation of spectral rendering to Lux and then they took it out :D
Why did they remove it?
I have no idea (it wasn't exactly the same project, LuxCore vs Lux), and PBRT, on which Lux was based, later moved to full spectral rendering.

I guess they feel they'd rather reduce register pressure a bit than support it.
