[Qgis-user] SAGA Mac OSX in QGIS 2.8.2

Thu Jun 4 07:23:26 PDT 2015

Yes, it's probably a parameter change not accounted for.  I bundle SAGA 2.1.4, and it looks like Processing uses 2.1.3 descriptions unchanged, even in the latest Processing.  I thought Processing supported 2.1.4, but maybe that's just a placeholder until changes (like this) are figured out.
