 # Comparing subsolvers for nonlinear least squares in JSOSolvers
 
-Migration note (JSOSolvers ≥ 0.11): subsolvers are now selected with a Symbol via the `subsolver` keyword. Replace any old usages like `trunk(nlp, subsolver_type = CglsSolver)` with `trunk(nlp; subsolver = :cgls)`. See `JSOSolvers.trunkls_allowed_subsolvers` and `JSOSolvers.tronls_allowed_subsolvers` for the list of accepted symbols.

 This tutorial showcases some advanced features of solvers in JSOSolvers.
