deformula 0.1.3 (2026-09-17)

Dropped the SystemRequirements: C++11 declaration and the Rcpp::plugins("cpp11") attribute. Support for requesting C++11 has been removed from R, and the request was flagged as obsolete by the CRAN checks.
Removed the unused cpp11 entry from LinkingTo.
Fixed the integration of integrands that take negative values (#2). Nodes were compared with the zero threshold without taking the magnitude, so every negative contribution was silently discarded; deformula.moneone(function(x) x, -1, 1) returned 0.5 instead of 0. An integrand that is negative over the whole range lost every node, so the sum never converged and the reported error was stop("Unknown error code.").
Fixed the convergence test so that an integral whose value is zero converges instead of running until max.iter.
Reaching max.iter and encountering non-finite values are now reported through the message component. Previously both raised stop("Unknown error code.").
