2.3

[holl-]

Features

• Higher-order fluid solver (experimental)
• Dual dimensions to represent matrices
• Sparse matrices (experimental)
• More built-in neural network architectures
• Neighborhood search (experimental, non-jittable)
• Tracing linear functions has been improved and is now part of the public API via math.matrix_from_function()
• Sparse ILU factorization
• General 2D line plots for tensors with 1 spatial + a vector dimension
• Dataclasses can now be used as arguments in jit_compile, functional_gradient, etc.
• The newly added resample now replaces Field.at as the preferred resampling function
• Jax COO sparse matrix support

Breaking changes

• math.map now returns multiple tensors for functions that have multiple outputs
• Sparse matrix generation via jit_compile_linear now returns a sparse matrix
• Removed unpack_dims alias. Use unpack_dim instead.
• PointCloud.color has been replaced by a new color argument in plot()
• PointCloud.mask() has been replaced by field.mask()
• Exchanged argument order for max_iterations and x0 in Solve()

Deprecations

• HardGeometryMask and SoftGeometryMask have been deprecated in favor of field.mask()
