nloptr 2.2.0 – Aymeric Stamm

A new version of the nloptr package has been released!

This release fixes a breaking bug which affects nloptr and its reverse dependencies and brings some minor tweaks and corrections along the way:

Minimal patch for build against nlopt 2.9.x (#176, @jaganmn): specifically, the issues were that (i) nlopt versions 2.9.x had one less algorithm in the enum list, namely NLOPT_LD_LBFGS_NOCEDAL was removed in these versions and put back in 2.10 and (ii) we were using inst/include in which we copied nlopt headers conditionally to build the package (e.g. listing it in PKG_CPPFLAGS) resulting in possible version conflicts.
Fix the 2 failed tests by adding one more termination criterion.
Update GHA workflows to latest versions.
Fix reverse LinkingTo dependencies by (i) unconditionally copying headers to inst/include and (ii) fixing cmake path search (#179, @astamm).
Fix for newly broken kergp package due to wrong usage of if statement inside paste() which works differently than when used inside c() (#180, @astamm).
Update artifact action to v4 (#174, @eddelbuettel).
Correcting some of the unit tests in test-banana (#167, @aadler).
Correcting some of the unit tests in test-global-wrapper (#166, @aadler).
Update the code in nloptr.c for compatibility with the R API, efficiency, and formatting (#169, @aadler).
Bugfix: ranseed expects an unsigned long but was passed as an integer, thus reducing the range of random seeds. It is now passed as a double and converted to a long (#169, @aadler).
Since v2.1.1: Fix the issue One of the unit tests for the isres() algorithm was failing on some CRAN builds because convergence is stochastic with slightly different results even with the same fixed seed prior to calling the function.
