In CVXR: Disciplined Convex Optimization

CVXR 1.0-14

• Address further inefficiency in use of diagonal matrices in qp2quad_form.R
• Add initial interface to clarabel solver

CVXR 1.0-13

• Address inefficient processing of cones for MOSEK (Issue 137 reported by aszekMosek)
• Fix extract_quadratic_coeffs to use sparse matrix and sweep in place for better memory use (reported by Marissa Reitsma)

CVXR 1.0-12

• Rmosek to be removed from CRAN, so moved to drat repo
• Cleaned up some problematic Rd files shown in CRAN results

CVXR 1.0-11

• Being more careful about coercing to dgCMatrix via (as(as(<matrix>, "CsparseMatrix"), "generalMatrix"))
• Modify all class inheritance checks to use inherits()

CVXR 1.0-10

• Now requiring the updated scs 3.0 as an import

CVXR 1.0-9

• Now importing ECOSolveR version 0.5.4 and higher
• Added fixes for Matrix 1.3 update
• Somewhat better typesetting for Power class documentation (Issue #86)

CVXR 1.0-8 to 1.0-3

• Conforming to CRAN suggestions on non-CRAN packages, but no actual changes.

CVXR 1.0-2

• Added exponential cone support for MOSEK and uncommented associated test.
• Added JSS publication DOI.

CVXR 1.0-1

• Many small fixes to solver interfaces
• Reference semantics for Parameter
• Warm start for OSQP and updates to solver cache
• Solver parameter defaults explicit now
• New tests added for solver combinations

CVXR 1.0

• Major release implementing reductions, many new solvers.

CVXR 0.99

• Bug fix: duplicated integer and boolean indices.
• Bug fix: correct typo in constraint specification to GLPK.
• Added tutorial articles based on v0.99 to CVXR website on using other solvers, integer programming, MOSEK and GUROBI examples.

CVXR 0.98-1

• Minor typographical fixes.

CVXR 0.98

• Dropped delay_load parameter dropped in reticulate::import_from_path, per changes in reticulate.

• Cleaned up hooks into reticulate for commercial solvers.

CVXR 0.97-1

• Minor typo and documentation fixes.

CVXR 0.97

• Added LPSOLVE via lpSolveAPI
• Added GLPK via Rglpk
• Added MOSEK
• Added GUROBI
• Bug fix: issue #25. All CVXR expressions retain dimensions. Culprit was drop = FALSE (in function Index.get_special_slice) as suspected.

CVXR 0.96

• Added a note that CVXR can probably be compiled from source for earlier versions of R. This is issue #24

• Using pkgdown. This also addresses issue #23

• Bug fix: issue #28 Function intf_sign (interface.R) was unnecessarily using a tolerance parameter, now eliminated.

CVXR 0.95

• Updated Solver.solve to adapt to new ECOSolveR. Require version 0.4 of ECOSolveR now.

• Updated unpack_results to behave exactly like in CVXPY. Added documentation and testthat tests. Documented in Getting Faster Results article.

CVXR 0.94-4

• First CRAN release 2017-11-20.
