 Fixed minor bug exposed by [#2441](https://github.com/ERGO-Code/HiGHS/issues/2441) in Highs::setSolution() for a sparse user solution when the moidel is empty, and only clearing the dual data before solving with modified objective in Highs::multiobjectiveSolve() so that user-supplied solution is not cleared.
 
+Prompted by [#2463](https://github.com/ERGO-Code/HiGHS/issues/2463), the HiGHS solution and basis files now match data to any column and row names in the model, only assuming that the data are aligned with column and row indices if there are no names in the model. This requires a new version (v2) of the HiGHS basis file. Basis files from v1 are still read, but deprecated. Now, when writing out a model, basis or solution, column and row names are added to the model - previously they were created temporarily and inconsistentyly on the fly. If the model has existing names, then distinctive names are created to replace any blank names, but names with spaces or duplicate names yield an error status return.
