SAGA 7.3.0 Simple Filter tool Unknown option 'MODE'

[mapninja]

Looks like MODE & RADIUS Parameters changed to KERNEL_TYPE & KERNEL_RADIUS?

Not a qgis bug -- try the "saga Nextgen" plugin if you need compatibility with different saga versions

[mapninja]

I'm curious about this not being a QGIS bug? Maybe it's a QGIS Mac Packager bug? I mean, SAGA version 7.3 is being packaged with the nightlybuild, right?

[PeterPetrik]

QGIS 3.16 on macOS is packaged with PROJ6 library. To be able to compile SAGA with this version, we have packaged SAGA 7.3.0. Unfortunately, QGIS on other OS have older SAGA versions, notably OSGeo4W contains SAGA 2.3. SAGA notoriously changes the arguments and API to the algorithms (even in patch releases), and therefore it is impossible to maintain the QGIS core SAGA plugin compatible with all versions. To solve this difficult issue, we propose to use SAGA-nextGen plugin (https://plugins.qgis.org/plugins/processing_saga_nextgen) instead of the core SAGA plugin. For the long term solution, it would be best to remove the SAGA core plugin from QGIS core completely, and leave the saga processing algorithms for the QGIS community plugins.
