This release includes several new pieces of functionality and some significant API changes:

  • Updated to Python-3 (exclusively) and SymPy-1.1
  • Renamed symbol types: DenseData->Function, TimeData->TimeFunction, PointData->SparseFunction
  • Introduction of a Grid class that provides the defaulting behaviour for space and time dimensions
  • Enable completely generic operators without explicit substitution of spacing variables
  • Addition of explicit start/end values for dimension iterations for operator invocation
  • Removed fixed dimensions with hard-coded loop bounds
  • Improvements to YASK backend resulting in functional acoustic operators (both forward and adjoint)
  • Addition of new seismic example notebook using Dask for shot-level parallelism

Minor changes:

  • Now using nbval to test notebooks
  • Separating Function and Symbol types in internal hierarchy
  • Make Constant a Symbol, not Function
  • Added ability to switch backends at runtime
  • Lots of internal refactoring...
