Stable Release
This marks the end of the restructuring changes. This means it includes the change of the solution type to AbstractVectorOfArray, moves out the noise processes and uses the new noise process interface, adds the "refined" problem types, adds mass matrices, finalizes the callback interface, finalizes the linear/nonlinear interface, and throws in some general patches. This is marked as stable as these have been in the list of changes since the beginning, and now are complete. The only other known future changes are
- linear operator types
- problem conversions/promotions
The first is a new future related to PDEs and thus it's DifferentialEquations 3.0 material, and will be non-invasive to add. Problem conversions/promotions would be nice, but not a priority right now so maybe 3.0 material. Should be non-disruptive too when that finally comes. So this sounds like a good stable place to set 1.0.0!
