whats-new.rstPreviously,
set_xindexsilently ignored any extra variables returned by custom indexes'create_variablesmethod, only adding variables that matched the original coordinate names. This prevented custom indexes from providing additional computed variables, limiting their usefulness for advanced indexing scenarios like weather forecasting where derived coordinates are needed.This change modifies
set_xindexindataset.pyto add all variables returned bycreate_variables(), not just those matching coordinate names. The implementation simply iterates through all returned variables instead of filtering by coordinate names.The fix enables custom indexes to provide computed variables while maintaining full backward compatibility. Existing code continues to work unchanged, but custom indexes can now return additional variables that will be properly added to the dataset, resolving the silent ignoring behavior that was confusing to users.
