Cvxgrp Scs Versions Save

1. Exponential cone projection now about 50x faster!
2. GPU version working again!
3. More testing.

Return ability to reuse workspace and update problem parameters.

Mostly under the hood refactoring and cleanup.

SCS 3.0 release. Some features:

1. Add support for quadratic objectives.
2. Add support for the box cone.
3. Improve reliability and robustness of acceleration.
4. Improve PSD cone projection.
5. Adapt the scale parameter on the fly.
6. Many under the hood stability and speed improvements.

Release 2.1.4.

Improved GPU indirect solver.

Bump to version 2.1.2.

Adds SCS() macro which adds scs_ prefix by default to all public functions. Various Windows fixes.

Release SCS 2.0.0. This includes several changes, most notably:

• Add an acceleration outer loop, this dramatically improves performance on most problems (that we tested).
• Acceleration requires LAPACK, so this is now linked against by default (instead of optionally as before).
• Since acceleration improves performance we have tightened to default tolerance from 1e-3 -> 1e-5, and also increased the default max number of iterations from 2500 -> 5000.
• Break out the interfaces for other languages to different repos.
• Add some C testing capabilities.
• Some internal renaming of functions and variables
