NEWS

• 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).

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

• 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)

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

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

• Now requiring the updated scs 3.0 as an import

• 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)

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

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

• 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

• Major release implementing reductions, many new solvers.

• 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.

• Minor typographical fixes.

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

• Cleaned up hooks into reticulate for commercial solvers.

• Minor typo and documentation fixes.

• 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.

• 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.

• 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.

• First CRAN release 2017-11-20.
