In the latest release, there are only a few minor but important bug fixes. However, users can enjoy a new promising method for catchment area calculation from DEM named 'Multiple Triangular Flow Direction', which has been contributed by Thomas Grabs. SAGA's developers welcome any help from the community in working through the bug list more systematically.
