The ability to control when output occurs has been enhanced and now is consistent with other objects in MOOSE that utilize the "execute_on" parameter (e.g., UserObject).
MooseEnums have been around for a few years in MOOSE. They are useful anytime you need to create a list of options for your custom objects. MooseEnums automatically verify that a supplied option matches an item in the list (case-insensitive). MOOSE has full support for using them with the InputParameters class as well.
We added a new feature to the phase-field module for reading data from image and stacks of images. The original purpose for this feature was to generate mesh from micro-structure data, as shown in the image.
Highlighting or coloring output in MOOSE is now easy to use. There are several color macro names that can be inserted into any stream object.
