Concatenate (Optional in) is deprecated in 4.1 what's the best alternative?

Hi,

I use a lot of “Concatenate (Optional in)” in my workflows. It seems to be deprecated in 4.1.

Should I just combine many “Concatenate” into 1 large metanode?

Any suggestions would be great.
Thanks,

Hey there,

You can use the normal concatenate node and add in option(dynamic) ports now. It’s a very nice feature. Refer to the Technical section of the What’s New in Knime page:
