This is a patch release that fixes several bugs:

In particular, #197 fixes a critical bug introduced in v2.4.0 that prevents certain large optimizations from running with SNOPT.

v2.4.0

pyOptSparse v2.4.0 release notes

This is a minor release that adds mdolab-baseclasses as a dependency. It should be automatically pip-installed from PyPI if it is not available locally.
No other user-facing changes are expected, but see #193 for full details. To be clear, external optimizers (SNOPT, IPOPT and ParOpt) do not have hard-coded default values (and have never had them hard-coded), but this is now explicitly stated. We do not maintain an options list so please refer to the documentation for each solver for details. For these optimizers, there is no options checking so it is up to each optimizer to decide how to handle unrecognized or invalid option names/values. This is again the same behaviour as before, but we have removed the misleading options table on the documentation site since we do not use those information.

Other minor changes:

  • Documentation updates (#186, #188)
  • Added missing offset attribute to integer dvs (#192)
