CVXR 1.0-15

  • Revert clarabel requirement and use enhance rather than import until really necessary (Issue 142).
  • Update return codes for user_limit etc to be infeasible_inaccurate to match CVXPY for gurobi
  • Add an S3 print method for result from solve().
  • Move upper_tri_to_full to C++
  • Drop use of R6 classes
  • Address bug in copying Power object (Issue 145).

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.
