Make fm_try_callstack() more robust against large callstack sizes; solves “C stack” crash issue for inla() error reporting (version 0.2.0.9007)
Fix fm_bbox.fm_mesh_2d() bug for "S2" and "M2" manifold meshes (version 0.2.0.9008)
Fix bug in fm_rcdt_2d_inla() that lead to ignoring the quality.spec argument (version 0.2.0.9009)

Remove long deprecated inla.mesh etc legacy methods; need to explicitly convert old objects. Retaining the inla.mesh etc class suffixes for now. (version 0.2.0.9001)

Add print methods for fm_basis and fm_evaluator objects (version 0.1.7.9003)
Add fm_manifold_get() generic method to extract manifold information from general objects, so that external objects can implement their own manifold information storage (version 0.1.7.9005)
Add fm_crs_plot() method for plotting fm_crs objects with optional graticules and Tissot indicatrices (version 0.1.7.9010)

Add loc plotting option to geom_fm.fm_mesh_2d and modify the ggplot mapping interface for interior and boundary segments in the same method (version 0.1.7.9009)
Add format="loc" argument to fm_as_sfc.fm_mesh_2d() for converting mesh node coordinates to sfc_POINT format (version 0.1.7.9009)

Update documentation and vector coordinate inputs to fm_lattice_2d() to clarify input interpretation and ensure correct boundary orientation (version 0.1.7.9001)
Add some length unit handling to fm_crs_bounds() (version 0.1.7.9008)
Add control argument max_batch_size to fm_bary.fm_mesh_2d(), that can be supplied via fm_basis(), for optional override of the default maximal batch calculation size, see #14 (version 0.1.7.9011)

Remove sp objects from fmexample data. Use fmexample_sp() to access them if needed (version 0.1.7.9004)
Move sp dependency to Suggests, and remove inlabru dependency (version 0.1.7.9006)
Further sp use protection (version 0.1.7.9007)
Increased deprecation warning and error messages for old unsupported methods

Fix regression bug in fm_manifold() that made it ignore all but the first given type options. See #16 (version `0.1.6.9001)
Fix plot.fm_mesh_2d vectorisation bug (version 0.1.6.9002)
Add new fm_subdivide() method for fm_mesh_2d meshes (version 0.1.6.9003)

Fix for hiding away-facing triangle edges in plot.fm_mesh_2d() and lines.fm_segm().
Fix duplicated fm_unify_coords.sf() method. Thanks to Pablo Paccioretti for debugging and reporting, see #13 (version 0.1.5.9001)
Use batched fm_bary.fm_mesh_2d() computations for data sizes of 2e5 and upwards. This improves performance of fm_basis()/inla.spde.make.A() for large data sets, see #14 (version 0.1.5.9002)
Automatically convert raw sfc samplers objects to sf objects in fm_int.list() (version 0.1.5.9003)
Detect and warn about unsupported use of fm_segm objects in fm_int.list() (version 0.1.5.9004)

Add fm_CRS() support for terra objects (version 0.1.5.9006)

Fix bug in fm_matern_sample() that prevented the use of a non-NULL loc argument. For earlier versions, the workaround is to make a separate call to fm_evaluate() after calling fm_matern_sample().
Improve speed of fm_block_log_shift() by an order of magnitude for multi-block cases.
Fix bug in plot.fm_mesh_2d for meshes with 2D coordinate storage (version 0.1.4.9002)

Fix bug in fm_rcdt_2d_inla() that gave different defaults for the extend and refine arguments when equal to TRUE, that should be treated the same as list() (version 0.1.2.9001)
Fix bug in fm_rcdt_2d_inla() to properly update n basis counter element when removing unused vertices. (version 0.1.2.9002)
Fix bug giving a spurious warning about inconsistent is.bnd for empty fm_segm objects, and inconsistent grp vector lengths. (version 0.1.2.9003)
Convert some of the old potentially unsafe C++ pointer methods to type safe C++17 features

Various documentation improvements, in particular for INLA compatibility
Modify mesh refinement tests to directly check the refinement criteria instead of the specific mesh result, to account for differences in floating point behaviour on M1 processors.
Modify tests of non-mesh-generation features to use precomputed meshes or meshes with stable properties
Protect against invalid tv inputs
Revert from \text{} to \textrm{}, as AMS extensions are only supported from R 4.2.2 (https://www.stats.bris.ac.uk/R/doc/manuals/r-devel/R-exts.pdf 2023-08-24, page 90), and CRAN oldrel for macOS is 4.2.0, not 4.2.3
