clarabel 0.11.3 (2026-08-23)
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 (2026-03-01)
- 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

savvy crate from 0.8.13 to 0.9.2
