Changelog

Sourced from Gridap's changelog.

[0.20.8] - 2026-06-01

Added

• Added type-stable methods to tensor_contraction and Base.permutedims(::MultiValue, perm): pass the arguments by Val. Since PR#1301.
• Added compose_glues and compress_adaptivity, which are tools that can be used to compress a mesh hierarchy (several levels of refinement) into a single adapted model. Since PR#1309.

Fixed

• Fixed bug for Raviart-Thomas on AppendedTriangulations. Since PR#1302.
• Fixed type instability in Cartesian mesh constructor. Since PR#1304.

Changed

• Changed how tagging works to improve compilation times and allow for nested derivatives involving more than one triangulation. Since PR#1297.

[0.20.7] - 2026-05-12

Added

• Added reindex_free_dof_ids(space, algorithm) to reorder the free DOFs of a FESpace for bandwidth/profile/fill-in reduction. Supported algorithms: :rcm (Reverse Cuthill-McKee), :sloan (wavefront minimisation), and :coordinates (sort by spatial coordinates, for Lagrangian spaces). An externally computed permutation vector can also be applied directly via reindex_free_dof_ids(space, free_dof_ids). Since PR#1299.

Changed

• Minor generalisation of return_value for LinearCombinationMap. Since PR#1298.

[0.20.6] - 2026-05-05

Added

• Make compute_facet_owners(...) more flexible, allowing the user to provide a function to select the owner from neighboring cells. Since PR#1291.

Fixed

• Fixed type instability for tensor operations between MultiValue and scalars. Since PR#1293.
• Fixed type instability in basis construction when user gives a non-concrete output type. Since PR#1294.
• Reverted most changes from PR#1277, which were having unnexpected consequences, in favour of simpler changes. Since PR#1290.

[0.20.5] - 2026-04-28

Fixed

• Fixed a bug for autodiff with empty target triangulation, see Issue#1288 . Since PR#1289.
• NewtonRaphsonSolver now correctly handles already-converged initial states and reports non-convergence properly. Previously crashed with @unreachable when starting residual was ~0. Now checks initial convergence and throws informative error instead of assertion failure. Since PR#1285.
• NLSolver now checks convergence status before returning solution. Previously, when nlsolve() failed to converge, the unconverged last iterate was silently returned. Now throws an informative error with iteration count and residual norm. Since PR#1283.
• Fix a bug where external types were not correctly parsed with generated functions in Polynomials, see Issue#1286. Since PR#1287.

[0.20.4] - 2026-04-23
