ECOS v2.0.4 released

[staticfloat]

Hello there, I've been going through updating binary dependencies on Homebrew; is there a reason to disallow ECOS v2.0.4? Can we relax the version constraint at all?

[mlubin]

@tkelman, mind bumping the windows binaries?

[tkelman]

I'm getting what looks like a test failure on win32

The failing test was added in the most recent commit - https://github.com/embotech/ecos/commit/359537187c20122059d3c93a219b3785797ef7a9. May be worth compiling on 32 bit Linux to see if it's not just a Windows problem.

@mlubin what's the status on this? am I slash should I be using the new version of ecos for my experiments?

[mlubin]

Everything should already be bumped to 2.0.4?

[chriscoey]

ok so this issue can be closed?

[mlubin]

Well except for the windows binaries
