New features:

  • TensorFlow: Seamless TensorFlow data pipeline integration, standard U-net architecture in phi.tf.standard_networks, CUDA resampling operator
  • Improved support for point clouds and sampled fields (SampledField), RK4 advection
  • Symbolic field math, Noise field to replace math.randfreq()
  • Support for STICKY / NO_SLIP domain boundaries and moving/rotating obstacles
  • Web interface: Quad view, improved color maps and more configuration settings, configurable axis order using physics_config.x_first()

Breaking changes:

  • Change in math.resample() for 'constant' boundaries. This affects only values sampled close to the boundary.
  • Inflows now use antialiased geometry by default.
  • (minor) Removed keyword arguments from Field.at() and Field.sample_at().
  • (minor) Scene.copy_calling_script() now has different keyword arguments.
  • (minor) GeometryMask only holds one Geometry and behaves in line with AnalyticField.
  • (minor) math.resample(): No longer accepts boundary 'zero' as an alias for 'constant'.

Deprecations:

  • load_state(): Use build_graph_input() instead.
  • buoyancy(): Use density * -gravity * factor in conjunction with Field.at() instead.
  • StaggeredGrid.from_scalar(): Use Field.at() instead.
  • world.add_all(): Use world.add() instead.
  • Dataset.add(), Dataset.remove(): Mutable datasets are not supported.
  • Geometry.value_at(): Use Geometry.lies_inside() instead.
  • union_mask(): Use mask(union()) instead.

This is the last official version with Python 2 and Python 3 support.
