clarabel 0.11.3

• clarabel_control() defaults now match Clarabel.rs exactly. Several had fallen behind upstream:
  • Chordal decomposition is now enabled by default for semidefinite programs: chordal_decomposition_enable, chordal_decomposition_compact and chordal_decomposition_complete_dual are TRUE, and chordal_decomposition_merge_method is "clique_graph". On a semidefinite program with a decomposable sparsity pattern this is dramatically faster — on a banded example with a 120x120 semidefinite cone, 0.007 seconds against 422 seconds. Two consequences: the dual variables reported for semidefinite constraints are not in general the same as before, and data updates are blocked when a decomposition actually takes place. Linear, quadratic and second-order cone problems are unaffected and remain updatable. Pass chordal_decomposition_enable = FALSE for the previous behavior.
  • reduced_tol_infeas_abs is now 5e-12, not 5e-5, matching upstream since Clarabel.rs v0.10.0. Smaller means less margin required, so the previous value was stricter than upstream; the change makes AlmostPrimalInfeasible and AlmostDualInfeasible marginally easier to reach on borderline problems.
  • direct_solve_method is now "auto", not "qdldl", matching upstream since v0.11.0. This build links only the QDLDL solver, so "auto" resolves to the same code path and results are unchanged.
• Removed two direct_solve_method options that never worked: "cholmod" (never existed in Clarabel.rs; it is a Clarabel.jl option) and "mkl" (requires a Pardiso feature this build does not enable). The accepted values are "auto" and "qdldl".
• Corrected the documented defaults for tol_ktratio (1e-6, was documented as 1e-7) and iterative_refinement_reltol (1e-13, was documented as 1e-12). The code was already correct; only the help page was wrong.

clarabel 0.11.2

• Added persistent solver API for warm starts: clarabel_solver(), solver_solve(), solver_update(), solver_is_update_allowed()
• Robustified Rust interface: type coercion, error handling, CscMatrix validation, and regex ordering fixes
• Switched all R-side error messaging to cli::cli_abort() with markup
• Upgraded savvy crate from 0.8.13 to 0.9.2
• Added examples to clarabel_control() and solver functions
